Q. Can I use AMSOIL AFF 0W-40 in my new 4-stroke 
     snowmobile?
A. 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...

Q. Can I use AMSOIL AFF 0W-40 in my car or truck?
A. AMSOIL AFF can most certainly be used in cars or trucks but 
    it is not our first choice for automotive applications. We offer
    a full line of automotive oils. AFF is specifically formulated for
    small recreational 4-stroke engines, and is an excellent
    choice for 4-Stroke outboards, ATVs, lawn equipment, snow
    blowers etc….

Q. How long have AMSOIL lubricants been on the market?
A. 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.

Q. What are AMSOIL Synthetic Motor Oils?
A. 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 oils.

Q. What are AMSOIL Synthetic Blend Motor Oils?
A. AMSOIL Synthetic Blend Motor Oils are a blend of synthetic 
    fluids and petroleum oils. They are combined to form an
    all season motor oil that demonstrates many of the
    performance features of synthetic lubricants.

Q. Can AMSOIL Motor Oils be used in any engine?
A. Certainly, AMSOIL Motor Oils may be used in any
    mechanically sound gasoline or diesel fueled engine.
    Basically, that means they are excellent for use in any
    vehicle’s engine.

Q. Will AMSOIL Motor Oils void the warranty of a new vehicle?
A. 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.)

Q. Are AMSOIL Motor Oils All-Season Oils?
A. Synthetic oils are made to protect and perform better than 
    petroleum oils at both high and low temperature extremes. 
    That’s 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. That’s extremely important for
    today’s turbocharged and small, non-turbocharged engines!
 
Q. Will using AMSOIL Motor Oils increase gas mileage?
A. Tighter government regulations and increases in engine 
    manufacturers’ demands are calling for more fuel efficient
    lubricants. AMSOIL Motor Oils reduce friction and 
    drag better than petroleum oils, resulting in significant fuel
    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.

Q. Are AMSOIL Synthetic Motor Oils and petroleum motor oils
    compatible?
A. AMSOIL synthetic motor oils are fully compatible with all
    petroleum motor oils, and there is no danger in mixing the
    two. Mixing AMSOIL and petroleum oil, however, is not a
    recommended as a general practice. Performance and long
    drain intervals will be sacrificed and the oil should be
    promptly changed, at maximum, within the next 3,000 miles.
 
Q. Why are AMSOIL Motor Oils capable of extended drain
    intervals?
A. 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.
 
Q. Will AMSOIL Motor Oils decrease oil consumption?
A. Yes. When used in mechanically sound engines, AMSOIL
    Motor Oils can rfeduce 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 Motor Oils are “cure-alls”
    for engines that consume oil because of mechanical
    problems.

Q. Is there a recommended procedure for changing to AMSOIL
    Motor Oils?
A. 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 Absolute Efficiency Oil Filter (EaO) every time
    you change oil. Should Oil Additives or After Market Products
    be added to AMSOIL Motor Oils? No, they are not necessary!
    AMSOIL Motor Oils are properly formulated under the
    strictest Quality Control procedure to provide superior
    lubrication performance.

Q. What types of synthetic base oil fluids does AMSOIL use?
A. As the developer of the world's first API qualified synthetic
    motor oil in 1972, AMSOIL has gained more experience than
    any other oil company in formulating automotive synthetic
    lubricants. AMSOIL draws on this experience to formulate 
    its products using a full range of synthetic base oil and
    additive technologies. AMSOIL will not be locked into any
    single base oil strategy. Performance is the bottom line.
    There are new types of base stocks being introduced, and
    there are additives that work best in one base stock or
    another. As technology changes, equipment changes and  
    the demands on lubricants evolve, AMSOIL will incorporate
    new base oil and additive chemistries if and when those new 
    chemistries will enhance the performance of AMSOIL
    products. Currently, each AMSOIL lubricant is formulated
    with the synthetic base oil or combination of base oils best
    suited to that lubricant’s application demands. They are 
    optimized using the most  advanced premium synthetic base
    oils. Although AMSOIL has publicly stated that its XL motor
    oils are Group III based and its other motor oils are PAO
    based, specific formulary information beyond that is 
    exclusive and proprietary. AMSOIL views synthetic base oils
    the same as it views additives. Each has its unique set of
    properties, and AMSOIL, based on its extensive experience,
    combines them differently for superior  performance in 
    any given application or operating condition (gasoline,
    diesel, racing, transmission, gear, extended drain, extreme
    temperature, etc.).

Q. I have a 2001 Ford F-350 Pickup with a Powerstroke Diesel
    with 7000 miles. I'm getting ready to change over to
    synthetic oil. What AMSOIL motor oil would you recommend
    to use?
A. AMSOIL Series 3000 5W30 Heavy Duty Diesel Oil is our
    premium top of the line product. While there are best uses
    for both our Series 3000 and our AMSOIL 15W40 Diesel
    and Marine Oil, Series 3000 is our recommendation for the
    Ford Powerstroke engine. It surpasses the API Energy
    Conserving Rating requirements designed to provide 
    significant fuel savings. It has highly effective anti foam
    agents to prevent oil foaming. Series 3000 offers better 
    protective film at higher temperatures than conventional
    SAE 40 oils while retaining fluidity at subzero temperatures.
