Synthetic Motor Oils Outperform Conventional Lubricants

1. Superior Wear Protection . . . Engines Last Longer

In the Four Ball Wear Test (ASTM D 4172) AMSOIL Synthetic 10W-30 Motor Oil outperforms the leading synthetic and petroleum motor oils. 

2. Improves Fuel Economy

AMSOIL synthetic lubricants have been credited with significant fuel economy improvement. In a fuel economy test with Class 8 trucks, AMSOIL synthetic diesel oil and drivetrain fluids combined to produce up to an 8.2 percent improvement.*

*SAE J1321 Joint TMC/SAE Fuel Consumption Test Procedure - Type II. 

3. Easier Cold Starts

AMSOIL synthetic motor oils stay fluid at remarkably low temperatures.

60 percent of engine wear occurs during initial start-ups. AMSOIL motor oils flow freely for fast delivery to critical engine parts. 

4. Superior High Temperature Performance

Reduced friction means cooler operating temperatures. Excessive oil temperatures can be reduced by 20 to 50 degrees when using AMSOIL motor oils. 

5. Reduces Deposits on Critical Engine Parts

Engines run cleaner, perform better.

Results of high temperature test. AMSOIL, on the right, was the only oil that did not show formation of sludge or deposits. 


6. Reduces Oil Consumption

Tests show the superior thermal stability of AMSOIL Synthetic 10W-30 (ATM) Motor Oil withstands the higher operating temperatures of today’s engines better than conventional products.

With AMSOIL, only 4.86% vaporizes, compared to much higher percentages with competing motor oils. The result: better fuel economy and wear protection with AMSOIL 10W-30 Motor Oil. 

7. Lower Cost, More Convenience

Motorists value savings. With AMSOIL Synthetic Motor Oils, 25,000-mile/one-year oil changes save time and money. With all the added performance benefits of AMSOIL synthetics, fuel economy, reduced oil consumption and better wear protection, your savings add up every mile you are on the road. 

8. Jet-Age Technology

Only synthetics can stand up to the extreme performance demands of a jet engine.  Every jet engine in the world uses synthetic engine oil. 

9. The First in Synthetics

In 1972, AMSOIL formulated the world’s first American Petroleum Institute certified synthetic motor oil.  With more than 30 years experience manufacturing and marketing synthetic motor oils, AMSOIL has been a consistent leader on the forefront of lubricant technology. 

10. Environmental Benefits, Too!

Fewer oil changes means less waste oil, fewer filters, less packaging to dispose of, and a better future for our children.
