About 5W-30 Synthetic-Blend Motor Oil
AMSOIL Synthetic-Blend 5W-30 combines conventional and synthetic base oils for drivers who want a step up from conventional oil. It is an option to compare when your vehicle calls for 5W-30 and an API/ILSAC-licensed oil.
Before you choose
Confirm 5W-30 and the required API or ILSAC specification in your owner’s manual, and follow the manufacturer’s oil-change interval.
How is synthetic blend different from 100% synthetic?
A synthetic blend mixes conventional and synthetic base oils. AMSOIL’s 100% synthetic lines are formulated for higher protection and longer intervals; compare both against your manual and driving. Ask Jeff for help gathering the right product information.
