25,000 Miles Without An Oil Change Using AMSOIL

I was always told to change my oil every 3,000 miles if I wanted to properly maintain my vehicle. How is it possible to drive 25,000 miles without an oil change using AMSOIL?

AMSOIL is designed to a much higher paradigm and has outstanding features and benefits compared to those contained in refined conventional oils.

AMSOIL Signature Series Synthetic Motor Oil is guaranteed to run 25,000 miles or one year in mechanically sound engines in normal service; 15,000 miles or one year in severe service. In fact, some AMSOIL diesel oils carry drain interval recommendations of up to 50,000 miles. AMSOIL coined the phrase “extended drain interval” and it’s been validated by nearly 40 years of industry testing and millions of over-the-road miles.

AMSOIL Synthetic Motor Oils provide extended drain performance because they resist breakdown better than conventional petroleum oils. AMSOIL Synthetic Motor Oils are formulated to prevent the formation of performance-robbing deposits and resist volatilization (burn-off), which alters viscosity and increases oil consumption. Finally, AMSOIL Synthetic Motor Oils’ superior additive packages, a key element in the oil’s ability to function, holds up under engine stresses, remaining serviceable for the full recommended drain interval.
