About AMSOIL Synthetic Oil

AMSOIL synthetic oils dramatically outperform conventional petroleum motor oils. They reduce friction, heat and wear for maximum power, performance and efficiency. In addition, AMSOIL synthetic oil resists high temperature burn-off, chemical breakdown and sludging which keeps engines cleaner. It's outstanding low temperature fluidity provides fast, dependable winter starts and immediate startup protection. The result: reduced automotive maintenance and repair. AMSOIL Synthetic Oils exceed the most demanding world-wide performance standards and meet warranty requirements for all domestic and imported passenger cars, both turbo-charged and non turbo-charged. Up to 35,000-mile or 1-year oil drain intervals.

 

Mixing AMSOIL With Other Oils

AMSOIL synthetic oil is fully compatible with conventional petroleum oils, so you may feel free to top them off with petroleum based oils or top off petroleum based oils with AMSOIL. However, keep in mind that mixing AMSOIL with other oils will reduce its effectiveness and will shorten oil drain intervals. Also, be sure to only mix like viscosity grades.

 

What Viscosity Should You Use?

In most cases you can simply go with the manufacturers' recommended viscosity grade. However, there is an exception (isn't there always?). AMSOIL Series 2000 0w30 has been designed specifically to be used for applications which recommend 5w30 or 10w30 viscosity grades. You will notice by looking at the technical specs for each oil that the 0w30 synthetic oil has a very high viscosity index which indicates that it will maintain its viscosity through a wide range of temperatures and extreme conditions.

Also note that its operating temperature range is quite broad. If you were to take a look at our comparison chart you would see that this range is broader than the 5W or 10w30 of most other brands of oil.

In addition, the extremely high quality synthetic base stocks and long life additives which are used in our Series 2000 oils ensure that they will maintain their high performance qualities over thousands of trouble-free miles (35,000 miles with the 0W-30, as opposed to 25,000 with our 5W and 10w30 motor oils).

However, if you decide not to go with our Series 2000 oils, you can rest assured that you will still be pleased with the performance of our standard synthetic, hp and motorcycle oils (5w20, 5w30, 10w30, 10w40, 20w50).
