AMSOIL Synthetic Lubricants / Amsoil Source of the World's Best Synthetic Lubricants

A. J. Amatuzio (President of Amsoil): Our company makes the best lubricants in the world, period, and challenges anyone or any other company to prove us wrong! That wont happen because our competitors know it's true.

A. J. Amatuzio, announced that the phrase "The First in Synthetics" is now a part of the Amsoil registered trademark. No other oil company in the world can now claim this.

A. J. Amatuzio explained how this all came to be Amsoil INC. He applied to have "The First in Synthetics" registered and was told that he must prove to the Trademark officials, with documentation, that Amsoil INC. was the first, historically. They also said by claiming to be first he must also mean Amsoil is the best in quality and performance.

So Mr. Amatuzio had to convince them that they had better products than any other oil company in the world. Amsoil began to present comparison documentation and test results backing up the claim that Amsoil hands down was and is the best. The trademark officials accepted the documentation to allow Amsoil to use "First" in part of their trademark.

The process still was not through yet. The trademark officials now required the government to notify all other oil manufactures that would be impacted by the decision, so they would have the right to abject before the decision would be official. They were all notified in writing and given 90 days to voice their opinions, object, or comment on this. After 90 days not one manufacture in the entire world responded.

Amsoil not only convinced the trademark office that Amsoil was the first historically, but also convinced them that Amsoil is the first in quality, and performance and still no other competitor objected!

What Bobby Unser had to say about Amsoil at the 30th anniversay convention.

Indy car racing legend Bobby Unser attended the AMSOIL 30th anniversary convention and stated that he has used AMSOIL motor oils in all his vehicles for many years, including all his race cars. In fact, he said all of today's high level racers use synthetic motor oils because the engines simply demand the higher quality of synthetics. Bobby got up on stage and told about how his race car differentials could not survive more than one race up Pikes Peak without needing to be rebuilt, until he started using AMSOIL. Then his differentials went all race season without needing to be rebuilt. This experience in Bobby's early years of racing began his long relationship with AMSOIL in all his race cars. Bobby went on to say that "AMSOIL is the Best Lubricant made, the Standard to which all others are judged.

Bobby Unser explained to us recently how AMSOIL was responsible for the complete absence in gear box related failures. "When you walked in the garage you may have seen a container labeled as Valvoline, Texaco or whoever the sponsor was but that's not what was in the bottle, It was AMSOIL. They would clean the bottles out and put amsoil in. - Bobby Unser Sr in the new "A.J. Amatuzio - An American Success Story (the 1.5 hour film on the history of AMSOIL).

Every single synthetic oil company today copied AMSOIL! They Copied AMSOIL! But they will never have the quality and performance AMSOIL has because they can't" - Bobby Unser Sr.

Bobby Unser 3-time Indy 500 Winner, 35 overall Indy Car wins, & 13-time Pikes Peak Hill Climb Winner.

There are several major NASCAR and other famous racing teams that use AMSOIL in their race cars yet the oil sponsors logo on the hood and quarter panels is not what is in the vehicle! They want you to believe it is, but it isn't.

Fact is, every successful major race car in the world uses synthetics, and most of them use AMSOIL synthetics. We know exactly who these racing teams are but are not permitted to advertise who they are because they have such a large amount of money at stake with their sponsors wanting the public to believe they are using the brand of oil that is advertised on the car.

Bobby Unser explained to us recently how AMSOIL was responsible for the complete absence in gear box related failures. "When you walked in the garage you may have seen a container labeled as Valvoline, Texaco or whoever the sponsor was but that's not what was in the bottle, It was AMSOIL" - Bobby Unser Sr in the new "A.J. Amatuzio - An American Success Story (the 1.5 hour film on the history of AMSOIL).

"Every single synthetic oil company today copied AMSOIL! They Copied AMSOIL! But they will never have the quality and performance AMSOIL has because they can't" - Bobby Unser Sr.

Back in 1972, the American Petroleum Institute's rating was first applied to a remarkable synthetic motor oil. It was the first of it's kind to meet auto service requirements, and it was formulated by Amsoil.

Since then Amsoil has produced a complete line of synthetic lubricants, capturing the attention of giant oil companies. And no wonder! Natural impurities in petroleum oil shorten it's life, and contribute to engine wear. There are NO IMPURITIES IN Amsoil... It's unique molecular design creates a product with amazing durability. Long lasting Amsoil synthetic motor oil doesn't boil away in extreme heat, and remains fluid in extreme cold. Amsoil synthetic motor oil is impervious to both hot and cold temperature operations. What¹s more, you don¹t have to change the oil as often because AMSOIL runs cleaner and lasts far longer than conventional motor oils.

The corporate giants who once said "it'll never catch on" now produce synthetic oil of their own. But none has the benefit of Amsoil's thirty years' of research and development. Switch to Amsoil synthetic motor oil... First of it's kind... The Pioneer.

So now you ask about other motor oil manufacturers. Well on the back of every bottle of Amsoil's Series 2000 0W-30, Amsoil's Series 2000 20W-50 and Amsoil's Heavy Duty Diesel Oil Series 3000 5W-30 have independent lab testing results posted on the label. Now if any of this info wasn't 100% accurate Amsoil would have a lot of explaining to do because the other brands of oil listed on their label would be taking Amsoil to court yet in 30 years this has never happened. The FTC has never filed a false advertising claim against Amsoil and Amsoil has been recommending 25,000 mile or changes since 1972!

Below are the graphs on the back label of these Amsoil products. The smaller the wear scar (the number) the better it protects your engine. The high the number the worse it protects your engine.

Mobil will not and does not recommend or guarantee 25,000 mile or one year oil drain intervals like Amsoil 5W-30, 10W-30, or 10W-30. Amsoil now has a motor oil recommended for 35,000 mile or one year. Series 2000 0W-30. You wont find anything like a extended drain interval on Mobil's bottle but it's written on every bottle of Amsoil motor oil. So Mobil's long time tag line of "Nothing Outperforms Mobil 1" is actually a lie. Our tests prove it!

One of the most important functions of motor oil is to capture and suspend contaminants and wear particles, preventing premature wear on an engine’s internal parts. Acting alone, motor oil would quickly become saturated with these contaminants and wear materials and would require very frequent changing, perhaps as often as every 500 miles, in order to effectively guard against wear. It is an engine’s oil filter which allows motor oil to last for an extended period of time.

The Amsoil Advantage
Many of today’s conventional oil filters make use of pleated paper or cellulose as their filtration media. Although these filters usually display good flow characteristics when new, they tend to become obstructed fairly quickly. In addition, these conventional filters exhibit limited capacity, longevity and ability to catch fine particles.

Amsoil Super Duty Oil Filters (SDF) are designed for maximum efficiency, capacity and longevity, while meeting the high flow demands of modern engine designs. In fact, with its advanced filtration media composed of a special Cellulose, Synthetic and Glass Blend, Amsoil SDF Oil Filters have over a 75 percent better combined efficiency/capacity rating than other popular oil filters as tested according to industry standards. Amsoil SDF Filters are also approximately 65 percent efficient at removing 10 micron particles. In addition, Amsoil SDF Filters are designed for extended drain intervals of 12,500 miles or six months (whichever comes first), making them ideal for use in conjunction with premium Amsoil Synthetic Motor Oils.

Amsoil By-Pass Filtration
Advanced engine designs place tough demands on an engine’s full-flow filter, most of which are capable of efficiently filtering out only coarser wear particles, generally greater than 20 to 25 microns. However, approximately 60 percent of engine wear is caused by particles in the 5 to 20 micron range. These tiny particles closely match the precision clearances between critical engine components, entering the spaces between bearings, rings and other components and damaging metal surfaces, altering tolerances, fatiguing components and generating additional debris. For the ultimate in filtration efficiency and wear protection, Amsoil offers the Spin-On By-Pass Oil Filter.

The Amsoil By-Pass Oil Filter provides the best possible filtration on the market, protecting against wear, oil degradation, rust and corrosion. Situated outside the main line of oil circulation, the Amsoil By-Pass Filter works in conjunction with the full-flow filter, thoroughly filtering 10 percent of the oil at a time and removing wear-causing contaminants down to less than one micron in size. The Amsoil By-Pass Filter effectively filters all the oil in a six quart system in about five minutes at an average speed of 45 mph.

Water enters motor oil as a combustion by-product or as a condensate. When it contaminates motor oil, it can cause serious engine damage by causing metal surface rust and corrosion, which increases friction and wear and deteriorates the close-fitting tolerances between engine components. It can also react with other contaminants to form corrosive acids, which also damage metal components. The Amsoil By-Pass Filter effectively removes up to a pint of damaging water, significantly increasing the time oil can be safely left in the engine.

The effectiveness of the Amsoil By-Pass Filter lies in its construction. Its high-capacity filtration medium is a special blend of virgin wood and cotton fibers, formed into discs, stacked and compressed. The center tube is all-steel, perforated for oil flow and wrapped with a fine mesh cotton screen. Each filter includes a mounting unit with a spin-on filtering cartridge, connected by hoses to engine ports. The entire by-pass system fits into most cramped engine compartments, allowing quick and easy access. Particles sized down to less than one micron are trapped and removed, while the filter’s thirsty cellulose fibers remove water.

By-Pass Filter Accessories:
The Amsoil Dual Remote Oil Filtration System allows an Amsoil Super Duty Oil Filter and an Amsoil Spin-On By-Pass Filter to be attached onto a remote mount, providing easy access for both filters. Remote placement of the Dual Remote system allows larger oil filters to be used and increases oil sump capacity.

The Amsoil Dual-Guard Filtration System links two Amsoil By-Pass Filter elements together for engines with sump capacities greater than 20 quarts. For detailed info on Duel By-Pass Filtration Systems Click Here.

Amsoil makes some of the best oil filters in the world. Regular oil filters you can pick up at your local parts store can filter in the range of 25 to 35 microns. Amsoil Ea oil filters do this in the range of 3 to 10 microns! They are also recommended for 25,000 miles or 1 year which ever comes first. Click here to see independent lab testing of how Amsoil Ea Oil Filters stand up against the competition.

Amsoil also has high efficiency filtration system that filter down to 1 micron and virtually eliminate engine wear. Oil change can be extended far beyond 25,000 miles with these systems. Using oil analysis then tells you when your oil needs to be changed. Many people are going 75,000 to 100,000 miles before needing to change there oil.

Know the Facts
Amsoil Saves You Money!

Amsoil extended drain intervals mean fewer oil changes,
long term savings and convenience

Example:

Conventional motor oil companies recommend 3,000-mile drain intervals

Conventional 10W-30 Motor Oil *(40 quarts needed for 25,000 miles)	@ $1.50/qt. x 40 =	$60.00
8 Standard Oil Filters	@ $4.00 per filter x 8 =	$32.00
	TOTAL	$92.00

Amsoil recommends 25,000-mile/1-year drain intervals

$36.50

* Comparison based on 25,000 miles driven per year and 5-quart oil capacity, with one quart top-off for filter change.

You save $36.00 per year using Amsoil premium quality synthetic motor oil and oil filters. And at Amsoil's Preferred Customer prices, you save $47.50!

Even if you drive only 12,000 miles per year, the cost for Amsoil is the same as you pay for petroleum oil now! (Of course being a Preferred Customer you'd still save money.) But you still get better protection, lower engine temperatures, easier cold-weather starts and less engine wear. All of these benefits add up to an engine that will last longer and need fewer repairs. Change your oil and filter today and in six months change the filter again. That's it! What could be more convenient and good for your vehicle, too

A good friend of mine (Michael Stevens) recently converted his 98 Ford F-150 and his 98 Ford Expedition over to AMSOIL. He was changing his oil every 2 months because of the mileage both vehicles were being driven by his wife and himself. He was going to a local quick lube station and being charged $30 for every oil change.

I asked Mike what he was spending a year on oil changes alone. We added it up. $30 for each vehicle every 2 months. That's $60 every 2 months. x that by 6 and your looking at $360 a year on oil changes!

Now even if he had been changing the oil himself he'd still be spending around $300 a year doing this.

Mike is a Preferred Customer and receives all his Amsoil products at Dealer Cost. (The prices shown are Preferred Customer prices, which are around 20% to 30% below retail prices. He is paying under $5.00 a quart. He needed 6 quarts for both trucks. That's 12 quarts of 5W-30 for under $5.00 a quart, x 12 = $54.60. Then he purchased an Amsoil EA Oil Filter Part# Ea34 for the F-150, Under ($7.50) and a Ea11 for the Expedition also under $8.00. That's $15.25. The Amsoil Ea Oil Filters are recommended for 12,500 miles or 6 months of service. So he'll need to change just the filters 6 months from now and replacing just the oil that was in the filters. So that is $15.25 for the 2 filters and half a quart added to each vehicle at under $5.00 a quart. Mike is now spending $89.65 a year in stead of the $360 a year he was spending.

That's a savings of $270.35!

Along with switching his engines over, (a 4.2L in the F-150 and 5.4L in the Expedition) he switched both transmissions over and the rear ends as well. (The rear ends will never need fluid replacement again)

Now he was changing his transmission fluid at the manufacturer recommended intervals of every 30,000 miles. He said he was taking the vehicles to the quick lube to have this service done. They charge $89.99 for a filter and fluid replacement. (This means dropping the transmission pan, changing the filter and the fluid that was in the pan) This type of service still leave around 50% of the old transmission fluid in the torque converter.

Now they charged $169.99 for a complete transmission fluid change. (This the same as above but also remove the old fluid that is in your torque converter as well.) This is by far the best service because it removes all the old fluid. The first service is in a way like only doing half a oil change. You can see why the second is better.

So every year he would spend the $169.99 and have both of his vehicles transmissions flushed and refilled. That's $339.98 a year!

Now Amsoil's Automatic Transmission Fluid (ATF) is recommended for 3 times the vehicle manufacturers recommended service length. There is no time limit of this fluid. So you can leave it in for 3 x what the vehicle manufacturer recommends instead of changing it once a year.

The Fords are recommended for transmission fluid changes every 30,000 miles. With Amsoil's ATF Mike is now going 90,000 miles between transmission fluid changes! He's using 14 quarts for both vehicles. That's 28 quarts total at a Preferred Customer price under $6.00 a quart x 28 = $165.20

Now Mike was spending $339.98 a year! After 3 years that's $1019.94!!! With Amsoil Mike is only spending $165.20 in 3 years! Mike is doing the complete transmission fluid changes himself. (No special tools are required what so ever.)

Mike is saving over $854.74.
Even if he has someone else change the fluid he is still saving over $700.00. Plus his gas mileage has improved!

Ten Reasons Why You Should Switch to Amsoil

Offers the latest technology for today's engines.

Dramatically extends oil change intervals.

Less oil used with extended drains means less oil disposed.

Increases fuel economy as much as 2 - 5%.

Reduces engine temperatures by as much as 25 degrees F.

Provides dependable extreme cold start protection.

Offers the world's finest engine and oil filtration.

Reduces oil consumption and harmful emissions.

Provides state-of-the-art additive systems and base oil stocks.

Provides the most comprehensive and knowledgeable staff in the industry to answer questions.

How Do I Know The Test Results Are Real?

Amsoil runs hundreds of tests to determine how their oils compare to others in the industry. Then they request independent labs to perform the tests again in order to verify the results by a third party.

That might not mean a whole lot to you. You might however, find it interesting to note that, Amsoil posts the results of the four ball wear test (shown above) on the label of every bottle of Series 2000 0W-30, Series 2000 20W-50 and Series 3000 5W-30.

If the results had been falsified or tampered with in anyway, wouldn't one of these big oil companies be taking Amsoil to court? Wouldn't Mobil be suing Amsoil INC for everything they are worth? Yes they would. As you know from the info posted above Mobil took Castrol to court because of false advertising.

Through out the years since 1972 not one company is suing Amsoil over these test results. Doesn't that say something about the test results? What about the fact that the FTC is going after all these oil additive manufacturers left and right, but hasn't ever contacted Amsoil.

The results speak for themselves.

Amsoil Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional, synthetic and synthetic blend 10W-30 motor oils were subjected to a series of motor oil tests.

Seven tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature / High Shear Test (HTHS) measures a lubricants viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high temperature service. Pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricants reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) indicates the degree to which a lubricant can impact cold weather starting. The impressive test results show Amsoil Synthetic 10W-30 Motor Oil outperformed the competitors in nearly every test.

Extends Oil Life
The Thin Film Oxygen Uptake Test (TFOUT) is used to evaluate engines oil's ability to resist heat and oxygen breakdown when contaminated with oxidized / nitrated fuel, water, and soluble metals such as lead, copper, iron, manganese and silicon. This test is designed to mimic the operating conditions of a gasoline engine.

Amsoil 10W-30 Synthetic Motor Oil has superior heat and oxidation resistance to control sludge deposits and extend oil life. Engines stay clean for maximum protection and oil changes are reduced, saving time and money.

The higher the number the better.

Protects Hot Engines
The High Temperature / High Shear Test measurers a lubricants viscosity under severe high temperature and shear conditions that are similar to severe service applications in an engine. In order to prevent wear, it is important for a lubricant to maintain it's protective viscosity level under severe operating conditions.

Amsoil 10W-30 Synthetic Motor Oil does not "shear back" and thin out like other motor oils. Its superior viscosity stability provides unsurpassed bearing protection for dependable engine operation, especially during hot operating conditions.

Maximizes Fuel Economy, Reduces Oil Consumption and Emissions
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions.

Amsoil 10W-30 Synthetic Motor Oil resists high temperature volatilization (evaporation) better than other motor oils. Amsoil Synthetic Motor Oil maintains peak fuel efficiency reduces oil consumption and emissions.

The lower the number the better.

Improves Cold Temperature Startup
The pour Point Test determines the lowest temperature at which a lubricants will flow. The lower a lubricant's pour point, the better protection it provides in low temperature service.

Unlike conventional oils that solidify in cold temperatures, Amsoil 10W-30 Synthetic Motor oil remains fluid down to -58* F. Amsoil Synthetic Motor Oil helps engines turn over easier and flows quickly to engine parts for critical start-up protection. Engines start faster and wear is greatly reduced for extended engine life.

Controls Acid Formation
Total Base Number (TBN) is the measurements of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil's TBN, the more effective is in suspending wear-causing contaminates and reducing the corrosive effects of acids over an extended period of time.

The high TBN of Amsoil Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminations and acids, providing superior protection and performance over extended drain intervals.

Helps Engines Start Easier
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and start ability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures.

The low cold crank viscosity of Amsoil Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.

Seven tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant's viscosity under severe operating conditions.

The impressive test results show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test.

Thin-Film Oxygen Uptake (ASTMD-4742)

The Thin-Film Oxygen Uptake Test evaluates the oxidation stability of lubricating oils. A mixture of the test oil and chemistries found in gasoline engine operation (oxidized/nitrated fuel, soluble metals and distilled water) are placed in a test vessel, which is pressurized with oxygen and placed in a heated bath. Anti-oxidant breakdown is evident when the oxygen pressure in the vessel rapidly decreases. At this point, the induction time (break point) of the oil is recorded. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil had the highest induction time of all the tested oils. In fact, it didn't reach its break point in over 500 minutes of testing.

The superior oxidation stability of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively resist the formation of engine deposits and sludge, keeping engines running clean and efficient and extending oil life. It also resists thickening, maintaining its superior wear protection and lubricating properties and maximizing fuel efficiency.

High Temperature/High Shear (ASTM D-4683)

The High Temperature/High Shear Test measures a lubricant's viscosity under severe high temperature and shear conditions that resemble highly-loaded journal bearings in fired internal combustion engines. In order to prevent bearing wear, it is important for a lubricant to maintain its protective viscosity under severe operating conditions. The minimum High Temperature/High Shear viscosity for a 30 weight oil is 2.9 cP. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil surpasses this minimum standard and displayed the highest High Temperature/High Shear viscosity in the group.

The superior viscosity retention of AMSOIL Synthetic 10W-30 Motor Oil in the face of severe temperature and shear conditions allows it to provide continuous, unsurpassed protection for engine bearings, extending equipment life and preventing wear.

NOACK Volatility (ASTM D-5800)

The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. A maximum of 15 percent evaporation loss is allowable to meet API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 10W-30 Synthetic Motor Oil outperformed its nearest competitor by over 30 percent.

The extremely low volatility of AMSOIL Synthetic 10W-30 Motor Oil allows it to maintain its superior protective and performance qualities throughout extended drain intervals, even when faced with severe operating temperatures. In addition, oil consumption and emissions are minimized and fuel efficiency is maximized.

Pour Point (ASTM D-97)

The Pour Point Test determines the lowest temperature at which a lubricant will flow when cooled under prescribed conditions. The lower a lubricant's pour point, the better protection it provides in low temperature service. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the lowest pour point of the tested oils.

The low pour point of AMSOIL 10W-30 Synthetic Motor Oil allows it to maintain its fluidity in extremely low temperatures, reducing drag on moving vehicle parts, providing critical engine components with quick, essential lubrication and easing startup in cold temperatures. Wear is greatly reduced and equipment life is extended.

Total Base Number (ASTM D-2896)

Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the highest TBN of the tested oils.

The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and performance over extended drain intervals.

Cold Crank Simulator (ASTM D-5293)

The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and start ability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. 10W motor oils are tested at -25°C and must have a viscosity below 7000 cP to pass. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil is well below the maximum requirement, while many of the competing oils barely pass.

The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.

Four Ball Wear (ASTM D-4172)

The Four Ball Wear Test determines the wear protection properties of a lubricant. Three metal balls are clamped together and covered with the test lubricant, while a rotating fourth ball is pressed against them in sliding contact. This contact typically produces a wear scar, which is measured and recorded. The smaller the average wear scar, the better the wear protection provided by the lubricant. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil produced the smallest wear scar of the tested lubricants.

AMSOIL Synthetic 10W-30 Motor Oil provides unsurpassed protection against engine wear. Equipment life is extended, and repairs, downtime and expenses are reduced.

AMSOIL INC. has been the leader in synthetic motor oil formulation since its introduction of the world's first API rated synthetic motor oil in 1972. By specializing exclusively in the synthetic lubricant technology, AMSOIL is able to optimize the most advanced chemistries available. The "Genuine Synthetic PAO Formulated" designation displayed on AMSOIL packaging indicates that the oils are formulated with Polyalphaolefin (PAO) synthetic base stocks. This chemistry is the industry's premier base stock technology. Unlike conventional mineral-based chemistries, AMSOIL PAO base stocks contain fully saturated, hydrogenated molecules and are free of wax and other impurities. Combined with an exact balance of premium additives, it delivers superior hot and cold temperature performance, resists oxidation and acid formation and provides long-term wear protection. AMSOIL "Genuine Synthetic PAO Formulated" oils have shattered the parameters of the most rigorous industry testing and set the standard for all other motor oils.

The Truth About Oil Changes

The whole point of using a premium synthetic oil is peace of mind. I like knowing that I can trust the oil in my car to protect my engine. I like knowing that 100,000 miles down the road, I won’t necessarily have to start looking for another vehicle (unless I’m ready). I also like knowing that when 20,000 miles rolls around, I still have a few thousand miles left to find time to change the oil.

I used to be a pretty regular 3,000 mile oil changer. I had a very hard time believing that an oil could possibly last longer than 5,000 or at best 7,000 miles. Changing at 3,000 miles was very safe and “assured” me of no mechanical breakdowns (I thought!).

When I started looking at synthetics, my perspective changed a little. I figured, if I was going to go out and buy a $25,000 new car, I wanted to get the most for my money. Just protecting against breakdown for a hundred thousand miles wasn’t enough. I don’t take my car to the mechanic and hope he doesn’t break it. I take my car to the mechanic so that he can make it better. The same can be true of your oil.

Let’s talk about oil changes first. If it’s necessary to change oil every 3,000 to 5,000 miles, then so be it. We should just do it, and accept that it’s an integral part of keeping our vehicles from breaking down. But, if it’s not necessary, why do it? Just because our Dad did? My Dad used to listen to 8-track tapes too. Now we’ve got these nifty little CD’s that sound clear as a bell and last pretty much forever. Am I going to listen to 8-track tapes? Probably not. I don’t change my oil every 3,000 miles anymore either.

Why Do We Change Our Oil?

There are only a few basic reasons why it is necessary to change your oil, and they all, in the end, have to do with decreased protection of your engine and decreased performance. If these elements can be minimized, then there would be little or no reason to change the oil.

OIL CHANGES: Part 1:

First, all oil breaks down. That generally will include basestocks and additives. Without focusing on performance characteristics, the most significant difference from one oil to another is how quickly breakdown occurs. Although there are many factors that contribute to the breakdown of an oil, heat is one of the most important. Depletion and decreased effectiveness of oil additives is also important, but that will be discussed later.

Petroleum oil begins to break-down almost immediately. A high quality synthetic, on the other hand, can last for many thousands of miles without any significant reduction in performance or protection characteristics. Synthetics designed from the right combination of basestocks and additives can last indefinitely with the right filtration system.

As alluded to above, the first major difference between petroleum and synthetic oil is heat tolerance. Flash point is the temperature at which an oil gives off vapors that can be ignited with a flame held over the oil. The lower the flash point the greater tendency for the oil to suffer vaporization loss at high temperatures and to burn off on hot cylinder walls and pistons. The flash point can be an indicator of the quality of the base stock used. The higher the flash point the better. 400 degrees F is the minimum to prevent possible high consumption.

Today’s engines are expected to put out more power from a smaller size and with less oil than engines of the past. Therefore, the engines run much hotter than they used to. That puts an increased burden on the oil.

Even the best petroleum oils will have flash points only as high as 375 and 420 degrees F. For today’s hot running engines, this may not be nearly enough protection. Just about any synthetic you come across will have a flash point over 430 degrees. High quality synthetics can have flash points over 450 degrees (Every Amsoil synthetic oil has a flash point of over 450 degrees F with some exceeding 475 degrees). As a result, you will see little noticeable breakdown due to burn-off.

Just as important is the way in which petroleum and synthetic oils burn off. As a refined product, petroleum oils molecules are of varying sizes. Thus, as a petroleum oil heats up, the smaller molecules begin to burn off. Since the ash content in most petroleum oils is very high, deposits and sludge are left behind to coat the inside of your engine. In addition, as smaller particles burn off, the larger, heavier molecules are all that is left to protect the engine. Unfortunately, these larger particles do not flow nearly as well and tend to blanket the components of your engine which only exacerbates the heat problem.

Synthetic oils, because they are not purified, but rather designed specifically from the ground up for lubrication purposes, are comprised of molecules of uniform size and shape. Therefore, even if a synthetic oil does burn a little, the remaining oil has the same chemical characteristics that it had before the burn off. There are no smaller molecules to burn-off and no heavier molecules to leave behind. Moreover, many synthetics, have very low ash content. As a result, if oil burn-off does occur, there is little or no ash left behind to leave sludge and deposits on engine surfaces. Obviously, this leads to a cleaner burning, more fuel efficient engine.

As a side note (as it really has little bearing on when to change your oil), synthetics do a much better job of “cooling” engine components during operation. Because of their unique flow characteristics, engine components are likely to run 10 to 30 degrees cooler than with petroleum oils. This is important, because the hotter the components in your engine get, the more quickly they break down.

OIL CHANGES: Part 2: Additive Depletion

It is true that the additives in many oils begin breaking down after only a few thousand miles. What needs to be recognized is that there are different quality “grades” of additives just as there are different quality grades of just about any other product that you buy. There are also different combinations of additives that tend to work for better and for longer when combined than when used individually.

Making a blanket statement that additives in oil die after only 2 to 3,000 miles is like saying that automobile tires will only last for 30,000 miles. To be sure, there are plenty of tires on the market that can only last for 30,000 miles, and then they’re toast. But, there are many tires on the market nowadays that will last over 75,000 miles.

The same scenario holds true for motor oils. Many oil companies are using the same additives in their oils as all of the other companies because they are cheap. That’s why the oil costs less. You get what you pay for. If they were willing to spend the money on top-quality additive packages for their oils, every synthetic on the market would be recommended for extended drain intervals, and they would all be more expensive. The technology has been around for years. The problem is that oil companies make more money selling a cheaper grade oil and making sure that you change it more often.

Mobil 1 is actually working on a 25,000 mile synthetic oil as we speak. They’ll probably introduce it in the next couple of years.

Viscosity Retention -- Shear stable viscosity index improvers help Amsoil synthetic motor oils maintain their viscosity in the range appro-priate to each grade over extended drain use. Conventional oils formulated with easily sheared viscosity index improvers often drop out of viscosity specification relatively quickly -- sometimes even before the end of a 3,000-mile oil drain interval. Viscosity loss leaves oils incapable of protecting engines from metal to metal contact and wear in high temperatures.

Contaminant Control -- Dispersants keep contaminants, including combustion by-products, suspended in oil. The rate of dispersant depletion depends on the motor oil's additive treat-rate and the oil's contaminant load. Premium synthetic motor oils are formulated with high additive treat rates specifically to allow extended drain intervals.

Acid Control -- Total Base Number (TBN) describes the acid neutralization ability of an oil, with higher TBN oils providing longer lasting acid neutralization. Most passenger car motor oils are formulated with 6 or 7 TBN. Many synthetic motor oils are formulated with 9-11 TBN. All Amsoil synthetic oils have TBN levels of 11 or better.

OIL CHANGES: Part 3: Oil Contamination

There is also the issue of contamination. Oil will be contaminated in three major ways. One will be through debris that comes in through the air intake. Once it makes it through the air filter, it ends up in your oil. Once in your oil, it starts damaging your engine.

The second source of contamination will be metal shavings from the inside of your engine. The lesser the quality of the oil, the higher percentage of these shavings because there will be more metal to metal contact inside the engine.

The third source of contamination will be from combustion by- products. Combustion by-products will generally raise the acidity of your oil, which causes corrosion in your engine. In addition, they will be left behind as the engine oil burns off and will collect on the inside of your engine as deposits. To maintain the viability of your oil as well as protection of the engine, the contaminants have to be removed/neutralized.

OIL CHANGES: Part 4: Air Filters

One of the best ways to help with this process is to keep most of the contaminants from ever getting inside the engine in the first place. That’s where your air filter comes in. Conventional paper air filters are pretty worthless. How many times have you removed your air filter for replacement only to find that you could write your name in the dust that collected around the air intake? That’s just the stuff that was left behind. Imagine the amount that actually ended up inside the engine.

Part of the problem is that traditional paper filters do not fit all that snugly in the air intake compartment. They’ve improved, but they’re still not great. More importantly, though, they let way too much debris shoot right through the filter element itself. As a side-note, they are not all that good at allowing for good air flow either.

You see, as a compromise to allow enough air flow for your engine to run “properly”, surface type air filtration media have to allow certain sized particles to flow through. If they made the filtration media any more tightly woven, not enough air would pass through quickly enough to keep your vehicle running. As a result, most paper filters (even when new) won’t catch anything smaller than about 20 to 40 microns.

That’s pretty small. The only problem is that 60% of engine wear is caused by particles between 5 and 20 microns (mainly because there is so much more of it). If you don’t keep that stuff out, it’ll eat away at your engine.

Consider an alternative air filtration device which is more like a sponge (actually, it’s foam). Because foam is “squishy” it can be made slightly larger than the air intake compartment so that when installed it fits very snug with no room for air to by-pass the filtration unit.

In addition, it has millions of “tiny” channels through which air can flow, but these channels are not straight channels. They twist and turn through the filtration media. Air can pa
