AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil

Understand this product

Extended-Life motor oil is designed around a boosted additive system and synthetic base oils for drivers considering longer service intervals. Its purpose is to maintain protection over the service period defined in the product documentation.

Review every condition attached to an extended interval, including time, mileage, operating severity and filter requirements. The first applicable limit controls the service plan.

Product selection and maintenance

Start with the component and its manufacturer’s requirements, then compare the exact product and grade. A product name or category is useful for browsing but does not establish compatibility.

The listed grade is 5W-30. This identifies one selection requirement; it does not replace the performance specification or component application. Compare this exact grade, rather than another grade in the same family, with your manual.
