Gasoline Motor Oils

Choose between AMSOIL’s main three lines! The Best Performer on the market which is the Signature Series for best performance and protection. Also popular is the value line of XL (Extended Life) for those who like to change oil more often but still have a better oil than the competition. The third is the OE line which was designed for service centers or generally for our customers wanting AMSOIL in a 2nd vehicle. It’s priced to compete with the so called synthetics which are labeled “Fully Synthetic” you find on the shelves. The OE is a 100% synthetic priced for vehicles which oil changes will be more frequent.

Also listed is our products for specific use, older products still available and specialty formulations.
