Why are AMSOIL synthetic motor oils capable of 25,000 mile / once-a-year oil changes?

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 oil.

 

Can AMSOIL synthetic motor oils be used in any engine?

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.

 

Is it true that switching to AMSOIL or other synthetic oils will void my warranty?

Absolutely not. In 1975, the US Congress enacted the federal Magnuson-Moss Act to regulate written consumer product warranties. An examination of the law reveals warranties remain intact when AMSOIL Synthetic Lubricants are used. Click HERE for the full details.

 

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 vehicle without affecting the validity of the vehicle warranty.

 

How long have AMSOIL synthetic lubricants been on the market?

In 1972 AMSOIL introduced the first synthetic motor oil with an API (American Petroleum Institute) Service Classification. 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 oils.

 

Will AMSOIL 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 Motor Oils are “cure-alls” for engines that consume oil because of mechanical problems.

 

Will synthetic motor oil clean the sludge from my engine and plug the oil filter and passageways?

Absolutely not. Switching from petroleum oil to AMSOIL in routinely maintained vehicles will not cause clogged oil filters or passageways, regardless of mileage. Sludge, which is caused by poor quality oil and neglected maintenance practices, would have to be present in significant amounts to plug oil filters and passageways. If this excessive amount of sludge is present in an engine, it is just a matter of time before oil filters and passageways clog, regardless of the installation of AMSOIL.

 

Are AMSOIL synthetic motor oils and petroleum motor oils compatible?

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.

 

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. 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!

 

Do new cars require a break-in period with petroleum before you switch them to synthetic?

AMSOIL Synthetic Motor Oil can be used during break-in trouble free. In fact, vehicles such as Dodge Viper and Chevrolet Corvette come factory filled with synthetic oil. Since most new vehicles come filled with petroleum oil, it only makes good sense to change to AMSOIL at the first scheduled oil change interval. New engine components generate high levels of wear metals and can contain contaminants from assembly. By allowing the engine to operate with the petroleum oil until the first oil/filter change interval, the wear metals and contaminants are removed prior to installing AMSOIL.

 

Is it true that installing AMSOIL or other synthetic oils will cause my engine to leak oil?

In modern vehicles, there is no risk of AMSOIL motor oil leaking. In fact, AMSOIL motor oil is fully compatible with modern seal materials. It is properly formulated to condition seals, keeping them pliable to prevent leakage.

 

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

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?

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.

 

Can AMSOIL motor oils be recycled?

AMSOIL synthetic oils can be recycled in the same manner as a petroleum-based motor oils. Synthetic oils can also be used in furnaces designed to burn waste oils.

 

What types of synthetic base oil fluids does AMSOIL use?

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. It is this extensive experience that provides the ability to maximize product performance through use of a full range of high-performance synthetic base oils, most notably polyalphaolefin (PAO). AMSOIL views synthetic base oils the same as it views additives, with each having its own set of unique properties. AMSOIL engineers its lubricants with the synthetic base oil or combination of base oils best suited to a specific lubricant’s application demands (gasoline, diesel, racing, transmission, gear, extended drain, extreme temperature, etc.).

 

AMSOIL INC. maintains an unwavering commitment to provide products that outperform the competition and deliver maximum benefits to all AMSOIL customers. Performance is the bottom line.

 

What are AMSOIL synthetic blend motor oils?

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.

 

Is there a recommended procedure for changing to AMSOIL motor oils?

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 aftermarket 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.
