Why do high-mileage engines need their own motor oil ?
As vehicles age, the focus shifts from performance to protecting their engines and components. High-mileage motor oils include additives to combat seal degradation with seal conditioners, keep oil consumption down, and eliminate sludge build-up within the engine. Top brands will also include extra detergents to clean away deposits and reduce oil burn-off, along with modifiers to lengthen the time between changes and oil top-ups. Although normal motor oil will help, when cars enter their twilight years, switching to high-mileage oil will help lubricate and clean the engine, helping avoid larger issues down the line.
The AMSOIL Difference
As one of the best synthetic motor oil brands in the country, our range of high-mileage synthetic motor oils delivers a proven formula to keep your engine moving. Our formula comes with enhanced anti-wear additives and a boosted detergent and dispersant package to prevent build-up.

Frequently Asked Questions
No Dumb Questions, Just Dry Dipsticks
When does an engine become high mileage?
An engine is considered high mileage at 75,000 miles or more. This 75,000-mile threshold is not to say that your engine is going to fail, but rather it has reached a point where wear-and-tear items such as belts and seals may need to be replaced and where oil consumption may increase due to sludge and build-up.
Can I still use normal motor oil if my engine is nearing high mileage?
Yes, you can still use normal motor oil if your engine is nearing high mileage. However, it is best to switch to high mileage once you tick over the 75,000-mile mark, as it offers the sludge-removal and cleaning properties that come with it. If you do not, you may see a continued decrease in performance and increased oil burning in your engine.
Does high-mileage motor oil work in European engines?
Yes, high-mileage motor oil can work with European engines, but you need to do the extra work to ensure it meets the required European specifications rather than just the API standards. The issue surrounds the very sensitive European engine emissions systems which can require a specific additive within the motor oil to work. If you have a European model, it is best to chat with an Amsoil oil expert to ensure the specific high-mileage oil we carry is compatible with your engine.
