Our research told us that there was a difference in the quality of engine oils.
  As we began to develop our business plan, we knew we wanted to be associated with only the very best performance products, and in doing so, we clearly came to realize that there were two significantly clear leaders in terms of performance and overall market share:  Mobil1, which comes from the factory in more top performance cars than any other synthetic, and of course Amsoil.  The very first synthetic for automotive use was developed by Amsoil in the 60's, and began to be sold as the first synthetic motor oil in 1972.  Amsoil has been the clear leader of unsurpassed quality ever since.  Industry accepted tests prove that Amsoil uses the very best blend of chemicals. 

We also understood that potentially millions of dollars and billions of gallons of unnecessary lubricant service is wasted when maintenance is not done when fluids really need changing.  We want to be an environmentally friendly company and add value to our customers in multiple ways.  For 35 years AMSOIL has known and guaranteed an oil change interval of 25,000 in non-severe service, and 15,000 or more using analysis in severe operating conditions.  We then learned that the first synthetic motor oil was engineered in the United States back in 1972 by Amsoil.  Since the development of the first synthetic, Amsoil continues to offer unsurpassed quality.  
Today, top European manufacturers are providing synthetic oil with extended service intervals of greater than 15,000 miles.  While there are many synthetic choices today, the first synthetic continues to provide data that it is a superior lubricant.  That same company continues to provide more strides and leads innovation in product development around many advanced lubricants used today.  What is the preferred oil our company chooses to distribute and install in our customer cars and business fleet vehicles?  Amsoil.

"Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and has followed the Amsoil lead with introductions of synthetic motor oils of their own.  They spend millions of dollars advertising their "new" and "revolutionary" products.  No one, however, can match Amsoil experience and technological know-how.  And no one delivers products like Amsoil.  Accept no substitutes - Amsoil is The First in Synthetics.

Frequently Asked Questions

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.  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. 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?

A. 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.

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 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.

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 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.

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.

Q.  Should Oil Additives or After Market Products be added to AMSOIL Motor Oils?

A.  No, they are not necessary! AMSOIL Motor Oils are properly formulated under the strictest Quality Control procedure to provide superior lubrication performance.
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. 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.

Q. 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?

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

A. 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.
