Built to Resist Breakdown and Protect Against LSPI
Extended-Life Synthetic Motor Oil maintains its fluidity (viscosity) under extreme conditions. Some oils break down and significantly increase in viscosity after extended periods of high-temperature operation, causing excessive oil consumption, engine deposits, accelerated wear, and difficult cold starts. AMSOIL Extended-Life resists oil breakdown, ensuring protection in extreme temperatures.
Extended-Life is fortified with a boosted additive package that neutralizes acids and resists sludge, corrosion, and carbon deposits. The extra protection provides peace of mind knowing your vehicle is getting premium protection and the convenience of extended drains.

Yes, Extended-Life is compatible with conventional and other synthetic motor oils. However, mixing other oils will shorten the oil's life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
