AMSOIL High-Mileage Synthetic Motor Oil

AMSOIL High-Mileage Synthetic Motor Oil is formulated for vehicles that have accumulated significant kilometres and may benefit from an engine oil designed specifically around the needs of older engines. High-mileage vehicles can present different lubrication challenges as seals, deposits and internal components age through years of service.

Designed for Older Engines

An older engine does not automatically require a thicker oil. The correct viscosity and specification should still be selected according to the engine and its operating requirements. A dedicated high-mileage formulation instead provides an option engineered around the conditions commonly encountered as engines accumulate kilometres.

Like any engine oil, a high-mileage lubricant must continue to protect against wear, deposits, heat and lubricant breakdown. Using a quality synthetic oil can help maintain dependable lubrication while supporting the continued service of an otherwise healthy older engine.

Choosing Oil for a High-Mileage Vehicle

Age or kilometres alone should not override the lubricant requirements of the engine. Check the required viscosity and performance standards before selecting a product. The AMSOIL Oil Standards Guide can help explain common engine-oil classifications, while the AMSOIL Vehicle Product Finder can identify suitable AMSOIL products for specific vehicles.
