Extended Life "XL" Motor Oils

AMSOIL XL Extended Life Synthetic Motor Oils provide better wear control, high- and low-temperature protection and increased fuel economy compared to conventional oils. Formulated with extended-drain boost technology, AMSOIL XL Synthetic Motor Oils provide superior performance for up to 10,000-miles/six months, or longer when recommended in owner’s manuals or indicated by electronic oil life monitoring systems.

Cost conscious business owners and fleet managers benefit from the extended drain intervals and wear protection of high quality AMSOIL XL Synthetic Motor Oils. Frequent oil changes are costly, time consuming and inconvenient, longer drain intervals reduce costs (labor, used oil disposal, facility demands) and improve environmental image.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, the First in Synthetics®, to do the best job protecting your engine.
