Whether you want the best possible wear protection, a quality synthetic oil at a lower initial price or something in between, we formulate an AMSOIL synthetic motor oil for you.

Advanced Protection

OEAMSOIL OE Synthetic Motor Oil helps provide better wear control, high- and low-temperature protection and increased fuel economy compared to conventional oils. The oil drain recommendations for many of today’s vehicles extend well beyond the traditional 3,000-mile (4,800-km) interval, some up to 12,000 miles (19,300 km) with electronic oil life monitoring systems. AMSOIL OE provides excellent protection and performance for the entire length of the original equipment manufacturer’s (OEM) recommended drain interval.
