Diesel Oil Viscosity Grade Has
Significate Inpact On Fuel Economy
Diesel fuel is a major expense for fleets
across the country, accounting for up to 50 percent of total operating costs. Therefore,
reducing fuel consumption is key to increasing operating profits. Improving fuel economy
is also a top priority for truck manufacturers in response to government regulations to
lower exhaust emissions.
In order for a
vehicle to maximize fuel efficiency, frictional losses in the engine must be cut to a
minimum. Fuel economy improves when more energy goes to propelling the vehicle and less
energy is used overcoming mechanical friction in the engine, including oil film resistance
between moving parts. Friction reduction must be maintained throughout changes in speed,
pressure, shear stress, contact geometry and temperature.
In passenger
vehicles, significant frictional loss occurs in the valvetrain. Oils formulated with
friction modifiers play an important role in improving fuel economy by reducing boundary
friction. However, frictional losses in the valvetrains of heavyduty diesel engines are
much less consequential. Instead, most frictional loss occurs in the piston assembly and
bearings, which usually operate under full film and mixed hydrodynamic lubrication
conditions where rubbing surfaces are separated by an oil film.
The viscosity grade
of diesel lubricants has a profound impact on friction and fuel consumption in heavy-duty
diesel engines. Higher viscosity oils provide adequate wear protection, but create
increased resistance to movement and higher frictional losses. Lower viscosity oils reduce
frictional losses, but unless they’re formulated with the right additive packages,
they may not be able to provide adequate wear protection, especially in high soot
conditions.
High-temperature/high-shear
(HT/HS) viscosity ratings, indicating changes in motor oil viscosity in high temperature
and shear conditions, is also important in the areas of fuel economy and wear protection.
In general, the lower the HT/HS rating, the better the fuel efficiency. However, if
it’s too low, wear protection is compromised. Today’s premium synthetic base
stocks and high-quality additives allow diesel oil formulators to blend low viscosity
lubricants that offer optimum HT/HS viscosities, excellent wear protection and maximum
fuel efficiency.
Recent laboratory
bench tests from Infineum show synthetic SAE 5W-30 heavy-duty diesel lubricants provide
significant increases in fuel economy over SAE 15W-40 Group II reference oils in both
steady state (motorway) and transient (city) driving conditions.
The level of fuel
economy improvement when using a lower viscosity lubricant depends on such factors as
engine design, operating conditions, drive cycle and fuel quality. However, even modest
gains in fuel efficiency are invaluable to fleet operators looking to cut expenses and
increase profits.

Service Life
In light-duty diesel engines, non-turbocharged
diesel engines, heavy-duty diesel engines, turbocharged diesel engines: drain oil at
intervals up to twice or more the oil drain interval length recommended by the engine
manufacturer if extended drain intervals are supported by the findings of a used oil
analysis program, or six months, whichever comes first.

gasoline engines and in marine craft and infrequently used gasoline automotive engines:
drain oil at intervals up to three times longer than those recommended by the engine
manufacturer or one year, whichever comes first.
In turbocharged passenger car gasoline
engines: drain oil at intervals up to twice the drain interval length recommended by
the engine manufacturer or one year, whichever comes first.
In high performance or racing engines:

Change AMSOIL Full-Flow Oil Filters at 12,500
mile or six month intervals, whichever comes first, in gasoline engines. In diesel
engines, change AMSOIL Full-Flow Oil Filters at 7,500 mile or six month intervals,
whichever comes first. Change other manufacturers' filters at the engine manufacturer's

Fleet Tests: Wear
Protection
AMSOIL synthetic
diesel oil’s protective chemistry was tested in fleets of Detroit Diesel, Cummins and
Caterpillar engines. The results show AMSOIL chemistry protects engines from ring
deposits, ring wear, ring breakage, bore polishing and liner wear better than other
chemistries do. Better protection provides significant savings through lower rates of oil
consumption, a longer period until first overhaul and longer engine life.
The test fleets
include 45 vehicles equipped with Detroit Diesel 6V-92TTA engines with an average 350,000
test miles per vehicle; 10 vehicles equipped with Cummins NTC-350 engines with 220,000
test miles per vehicle; 21 vehicles equipped with Caterpillar 3406 DITA engines with
220,000 test miles per vehicle. All results shown are averages.

Ea Oil filters
are recommended for 12,000 miles when installed on a diesel engine. These filters filter in
the range of 10 microns vs. your off the shelf oil filter which filters in the range of 25
to 30 microns.

AMSOIL recommends 3 times the oil drain
interval of the vehicle manufacturer, when using AMSOIL's diesel oil in a diesel engine.
Oil analysis has shown that 20,000 miles is the normal mileage reached before the oil
analysis recommends changing the oil.
If your interested in even longer oil
change intervals AMSOIL By-pass filtration system is what your looking for. Click Here for details. This
system uses your regular oil filter, but also uses a large secondary filter. Your normal
oil filter will be changed at 7,500 miles and the larger secondary filter will be changed
at 20,000 to 25,000 miles or when ever a oil analysis recommends changing. The benefits of
this system are that wear virtually is illuminated inside the engine because the larger
by-pass filter, filters down to 1 micron! This keeps the oil analytically clean and allows for extend oil
drain intervals. 100,000 miles and longer are normal for a vehicle with a by-pass
filtration system installed.

AMSOIL also manufacturers Air filters that will last the life
of your vehicle. They only need to be cleaned every 20,000 to 25,000 miles. They flow just
as good as K&N filters do but filter much more of the air entering your engine, also
extending the life of your vehicle. Gas mileage is also improved with this filter.
AMSOIL
2 stage Air filters are made for the Chevy Duramax, Ford Power Stroke, & Dodge
Cummins Diesel engines.
AMSOIL's ATF fluid is
recommended for 3 times the vehicle manufacturer recommended interval. It's engineered to
provide outstanding high temperature protection as well as superior cold weather service.
Shifts will become smoother and transmission temperatures will drop.
If your interested in your automatic transmission not
slipping between shifts AMSOIL's Powershift transmission fluids will illuminate it. The
fluid doesn't allow the clutches to slip between shifts improving the transmission
performance and lengthening it's life. Heat is greatly reduced. Shifts become much firmer. Click
