General Questions and Answers
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?
It is recommended that you use either AMSOIL Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD) or AMSOIL Synthetic 15W-40 Heavy-Duty Diesel and Marine Motor Oil (AME) for this diesel application. HDD is the preferred choice for better fuel economy, cold weather performance and mixed gasoline and diesel engine fleets. It provides better protection compared to conventional 15W-40 mineral based oils with its superior film strength and enhanced anti-wear additives. AMSOIL AME is a premium oil that matches many manufacturers viscosity recommendations. It outperforms competitive 15W-40 oils and is a lower cost option compared to AMSOIL HDD.

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

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 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.
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 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.
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.
I am considering replacing the petroleum oil with AMSOIL synthetic oil in an engine that has 50,000 miles on it. I have heard that synthetics might clean the engine and cause plugging of the oil filter and passageways. Is this true?
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.
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.
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.
Situation: AMSOIL INC. has been informed that some AMSOIL Dealers and their customers have experienced problems with their local Ford Dealership service department when bringing in the new AMSOIL Universal ATF for installation in their Ford vehicle transmission. They have been told that: A) You cannot put a Mercon V labeled transmission fluid in a Mercon application. B) That you cannot put a Mercon labeled transmission fluid in a Mercon V application (this is true). C) That you cannot put a dual usage labeled ATF product in the Mercon application or the Mercon V application. Since the new AMSOIL Universal Transmission Fluid is labeled dual usage, recommended for both Mercon and Mercon V applications, some Ford Dealership service managers are telling their customers that if they put the AMSOIL Universal ATF product in their transmission it will void their transmission warranty.
Answer: At least one oil companys ATF product with a Mercon V rating does not also meet Mercon performance requirements. This has apparently caused a great deal of confusion about allowing Mercon V ATF to be back serviceable in Mercon applications. The AMSOIL Universal ATF has been formulated to meet or exceed both the Mercon and Mercon V specification, as well as G.M. Dexron III and Chrysler ATF+4. It is fully supported through documented testing. It is recommended for and can be used in ALL of the applications listed on the label. PERIOD.
If someone is misinformed on this issue and actually denies a manufacturers warranty coverage because of the use of AMSOIL Universal ATF Fluid in one of the applications for which it is recommended by AMSOIL INC., the AMSOIL Warranty coverage would apply. The consumers transmission would be repaired under the AMSOIL Warranty. AMSOIL INC. and our insurance company will legally pursue the dealership or the manufacturer to recover our costs. AMSOIL INC. would not make the recommendations on our label, or issue this statement, if we were not completely confident of our position on this matter. While we cannot control what individuals say about this subject, we can and do insure that consumers can use our product with complete confidence and without risk.
