General Questions and Answers
Can I use AMSOIL AFF 0W-40 in my new 4-stroke
Absolutely! AMSOIL AFF 0W-40 was specifically
formulated for use in small, hard working 4-stroke engines. AFF
is ideal for 4-cycle snowmobiles, ATV's, personal watercraft,
4-stroke boat motors, lawn equipment etc...
Can I use AMSOIL AFF 0W-40 in my car or truck?
YES. AMSOIL AFF 0W-40 can be used in
in any gasoline 4-stroke automobile engine. Recommended change
intervals are at 7500 miles, or 6 months. AMSOIL AFF can also
be used in diesel powered cars or trucks, with change intervals
as recommended by your vehicle manufacturer.
How long have AMSOIL Synthetic Lubricants been on the market?
AMSOIL introduced the first synthetic motor oil with an API (American
Petroleum Institute) Service Classification in 1972. Since that
time, AMSOIL has varied and expanded its product line.
What are AMSOIL Synthetic Motor Oils?
AMSOIL Synthetic Lubricants are fuel efficient, extended life
lubricants manufactured from select synthetic base stocks and
special purpose additives. These lubricants provide improved overall
performance characteristics when compared to conventional petroleum
Can AMSOIL Synthetic Motor Oils be used in any engine?
Certainly, AMSOIL Synthetic Motor Oils may be used in any mechanically sound
gasoline or diesel fueled engine. Basically, that means they are
excellent for use in any vehicles engine.
Will AMSOIL Motor Oils void the warranty of a new vehicle?
Absolutely not! Manufacturers warranties are based upon
the use of oils meeting specific API Service Classifications,
for example, SJ/CF. (AMSOIL lubricants meet the current API Service
requirements and, thus, are perfectly suited for use in any new
vehicle without affecting the validity of the new vehicle warranty.)
Are AMSOIL Motor Oils All-Season Oils?
Synthetic oils are made to protect and perform better than petroleum
oils at both high and low temperature extremes. Thats why
every jet engine in the world is lubricated with synthetic oil.
AMSOIL Motor Oils have extremely low pour points and flow readily
at extremely low temperatures for easier winter starting and significantly
reduced engine wear. At high temperatures, no conventional motor
oil can compare to the overall protection AMSOIL Synthetic Motor
Oils provide. Thats extremely important for todays
turbocharged and small, non-turbocharged engines!
Will using AMSOIL Synthetic Motor Oils improve fuel economy?
Tighter government regulations and increases in engine manufacturers
demands are calling for more fuel efficient lubricants. AMSOIL
Synthetic Motor Oils reduce friction and drag better than petroleum oils,
resulting in significant fuel economy increases. In a recent 1.2
million mile demonstration, AMSOIL Lubricants showed a 4.5% increase
in gas mileage. Other tests have shown increases of as much as
15% under certain weather and driving conditions. Yet, because
every vehicle is different, as are driving habits and conditions,
it is difficult to accurately project an exact increase.
Are AMSOIL Motor Oils compatible with other motor oils?
Yes. AMSOIL Synthetic Motor Oils are compatible with all other synthetic
or petroleum motor oils.
Why are AMSOIL Synthetic Motor Oils capable of extended drain intervals?
AMSOIL Synthetic Motor Oils are highly resistant to the destructive
effects of heat, and do not break down like petroleum oils. This
means that AMSOIL Motor Oils can provide much longer drain intervals
than conventional lubricants.
Will AMSOIL Synthetic Motor Oils decrease oil consumption?
Yes. When used in mechanically sound engines, AMSOIL Motor Oils
can reduce oil consumption. Under test conditions, a reduction
of as much as 42% was demonstrated for prolonged periods. However,
this should not be taken to mean that AMSOIL Synthetic Motor Oils are cure-alls
for engines that consume oil because of mechanical problems.
Is there a recommended procedure for changing to AMSOIL
There are no special requirements; however, in older vehicles
or those with high mileage, it may be advisable to use AMSOIL
Engine Flush first. This will ensure that the engine is clean
and free of any accumulated contaminants which might have an effect
on the service life of AMSOIL Motor Oils. In all cases, it is
good judgement to install a new AMSOIL Super Duty Full-Flow Oil
Filter (SDF) every time you change oil.
Should Oil Additives or After Market Products be added
to AMSOIL Motor Oils?
No, they are not necessary! AMSOIL Synthetic Motor Oils
are properly formulated under the strictest Quality Control procedure
to provide superior lubrication performance.
