Extended drain intervals between oil changes
AMSOIL Applauded for Extended Drain Technology AMSOIL founder A.J. Amatuzio coined the phrase "extended drain intervals" back in 1972 with the introduction of AMSOIL 10W-40 Synthetic Motor Oil, formulated for 25,000-mile/one-year drain intervals. Not only was AMSOIL motor oil the first synthetic oil to pass American Petroleum Institute (API) service requirements, AMSOIL INC. was the only motor oil company promoting oil drains beyond 3,000 miles.

Synthetic motor oils resist chemical breakdown and sludging
AMSOIL synthetic motor oils resist chemical breakdown and sludging which keeps engines cleaner. They have been specifically designed not to oxidize, volatilize or shear back, resulting in a motor oil that lasts longer than conventional petroleum motor oils. While petroleum motor oil manufacturers recommend oil changes every 3,000 miles, AMSOIL synthetic motor oils protect engine components up to 35,000 miles or 1 year, dramatically extending oil change intervals.
