2. 02

   

   XL Synthetic

   Up to 20,000 miles or one year in normal service

   A step up from conventional without the Signature Series interval. Strong cold flow, OEM-spec coverage, and a price that pays back on the second change. Severe service (commercial or fleet use, excessive idling, or frequent towing, hauling, plowing or dusty driving) calls for a shorter interval: AMSOIL lists up to 12,000 miles or one year. Follow AMSOIL’s severe-service recommendation or your manufacturer’s interval.

   Best for: Newer vehicles under warranty, mixed fleets, cost-conscious households
