Q. I have read the NOACK tests
and the "3,000 miles oil change" fallacy. I have been using the AMSOIL Series
2000 0W-30 synthetic oil, AMSOIL SDF-29 filter and AMSOIL Air Filter. I have been
following directions cleaning and re-using the air filter on a once-a-year basis and
changing the oil filter twice a year. I leave the oil in for the full year. That amounts
to between 5,000 and 6,500 in the one year period.
I have recently purchased a brand new 2001
Pontiac Grand Am with the 3.4L engine. I also have purchased the GM Factory extended 6/60
warranty. I received the warranty book and read it. Much to my surprise I find the
following reference under "Your Responsibilities" in the book:
"YOU must properly maintain the covered
VEHICLE which includes, but is not limited to, changing the engine oil at a minimum of
every 3,000 miles or as recommended by the vehicle manufacturer. If requested, proof of
required service, including receipts and work orders showing date and mileage of the
VEHICLE at the time of service must be presented to US in the event of a FAILURE or
CLAIM."
Because of this I fear switching to the AMSOIL
0W-30 synthetic oil and oil filter and leaving it in the engine for the full year or
35,000 miles thus risking voiding the factory warranty. Is there anything you can do to
contact GM and convince them of the fallacy of the 3,000 mile oil change and convince them
to use and recommend AMSOIL synthetic oil in their cars? They are convinced enough to use
Havoline "extended" drain interval antifreeze, why won't they see the advantages
of AMSOIL synthetic 0W-30 oil?
A. The language in the extended
protection plan was written by an insurance company, and is definitely intended to
intimidate you into changing your oil every 3,000 miles. They are doing everything they
can to try to limit their liability for claims and create “wiggle” room. What’s
new!
All of the vehicle OEMs in the U.S. have agreed that a warranty cannot be denied because a
customer was using any brand of motor oil at any length drain interval unless an engine
failure was directly attributable to the oil or drain interval. For example, if your
radio, power steering unit, air conditioner, etc., broke down, they could not void the
warranty that covers those items because you were changing your engine oil at 6,500 miles
or one year. If it is not an oil related failure, they cannot void the warranty. The law
supports this position.
If your engine failed, and the manufacturer denied your warranty for repair due to your
using extended drain intervals, then you would submit your claim to the AMSOIL Technical
Services Department for handling. (See the
AMSOIL
Limited Warranty.) Our staff will analyze the oil, and if we are able to provide
documentation that proves the source of the problem was other than the oil, and that in
turn allows your claim to be processed under the original warranty, then we will. If no
proof can be assembled regarding the source of the problem, our insurance adjustor will be
dispatched to resolve the claim. A warranty claim being denied because of the use of
extended drain intervals is an extremely rare occurrence. That’s because motor oils
do not cause engine failures … dirt, glycol and other mechanical problems do.
Ironically, in Europe the auto manufacturers recommended drain intervals are from
12,000-18,000 miles using petroleum products, and are moving even higher. In the U.S., it
has been published that auto manufacturers are also going to be moving toward extended
drain intervals of up to 15,000 miles in the not too distant future. G.M. is currently
moving toward a system that tells you when to change your oil based upon a computer
program that evaluates your driving habits. Some other car companies are planning on
having an on-board oil analyzer to tell you when to change your oil. This will allow for
shorter drains for poorer quality oils and longer drains for higher quality oils, where
G.M.’s system will not distinguish between the two. As these changes develop, so will
the language in owner’s manuals as well as extended warranty policies.
You’ve used our products successfully for 7 years, drive extremely low
miles per year, and are following all of our directions for air filter
cleaning and oil filter changing. You have our warranty coverage to fall
back on in the unlikely event of an engine failure that is not covered
by your vehicle warranty. I hope you will not be intimidated by the
language in your extended warranty policy and will continue to use the
highest quality and best performing products that you can, AMSOIL.
