I heard that new cars require a break in period with petroleum before you switch them to synthetic. How long should this break in period be?

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.

Will using AMSOIL Engine Flush in motorcycle engines damage the wet clutch?

It may soften clutch materials to the point where clutch packages could be damaged, and is not recommended for this application.

Can AMSOIL Motor Oils be recycled?

Regarding used synthetic oils, they 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.

Why does AMSOIL say to change the AMSOIL SDF Oil Filter at six months regardless of the mileage. I have only gone 5,000 miles and figure that I could go the whole year without changing it and be good.

Once an engine is run with new oil, byproducts of combustion are introduced into the oil. These byproducts are harmful chemicals that continue to degrade the integrity of the motor oil as well as the oil filter media even though the engine may be off. This is why a time limit is published as well as mileage. Short trip driving can be just as detrimental to motor oil and filters as high mileage use, and even more so in some cases. It’s possible that the oil is still intact at the end of the published time limit, but oil analysis would be needed to verify this. Heavy trucks use this practice regularly, however in small sump capacity engines, the cost of the test is nearly as much as the cost of an oil change.

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?

AMSOIL Series 3000 5W30 Heavy Duty Diesel Oil is AMSOIL's premium top of the line product. While there are best uses for both the Series 3000 and the AMSOIL 15W40 Diesel and Marine Oil, Series 3000 is AMSOIL's 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.

What is the actual oil weight for the following suspension fluids: STL - Shock Therapy Light and STM - Shock Therapy Medium

Shock Therapy Light corresponds to a 5 wt. and Shock Therapy Medium corresponds to a 10 wt.

What are the correct dilution ratios for BriteSide T6 Cleaning Concentrate?

	Task 1	Task 2	Task 3	Task 4	Task 5	Task 6
Capfuls	Full Strength	16	8	4	2	1
CC's	Full Strength	142	72	36	18	9

 

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 AMSOIL's first choice for automotive applications. AMSOIL offers 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….

How long have AMSOIL 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 oils. 

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. 

Can AMSOIL Motor Oils be used in any engine?

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. 

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. 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! 

Will using AMSOIL Motor Oils increase gas mileage?

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 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 Motor Oils are compatible with all other synthetic or petroleum motor oils. 

Why are AMSOIL 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 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. 

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 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 Motor Oils are properly formulated under the strictest Quality Control procedure to provide superior lubrication performance.
