About 5W-20 High-Mileage Motor Oil
This 5W-20 High-Mileage formulation is intended for the maintenance needs of engines with accumulated miles. It gives you a purpose-built alternative to compare with AMSOIL’s other gasoline oil lines while retaining the viscosity your engine requires.
Before you choose
Check that your engine calls for 5W-20 and meets the product’s listed application requirements. Investigate persistent oil loss, leaks, or warning lights with a technician; oil selection is only one part of maintenance.
Is high-mileage oil a substitute for an engine repair?
No. A high-mileage formulation can be part of your maintenance routine, but it does not replace diagnosis of leaks, abnormal oil consumption, or mechanical problems.
