Over thirty-five years ago, 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.
Today, AMSOIL offers a complete line of extended life oil and filters for most gasoline and diesel powered vehicles and equipment.
EAO Oil Filters (25,000-mile/one year.) & EAA Air Filters (100,000-mile/four year.)
Designed for extended life are recommended for extended interval drains.The Introduction of AMSOIL Ea filter line has placed AMSOIL at the forefront of the filtration world. The nanofiber technology used in Ea Filters is new to the auto/light truck market, and available only from AMSOIL. These revolutionary new filters were the beginning of a filtration overhaul at AMSOIL.
