Amsoil offers three different levels of synthetic motor oil designed for the kind of driving your gasoline powered vehicle is used for.
Signature Series Synthetic Motor Oil
AMSOIL Signature Series Synthetic Motor Oil represents the pinnacle of lubrication science.
It is the result of over 40 years of synthetic lubricant engineering.
Signature Series provides 75 percent more engine protection against horsepower loss and wear than required by a leading industry standard.*
XL Synthetic Motor Oil
Protection-boost technology maintains maximum wear protection for up to 10,000-mile/six month drain intervals, or longer when recommended in owners' manuals or indicated by oil life monitoring systems.
Excellent for high-mileage vehicles. Save time, money and effort.
OE Synthetic Motor Oil
AMSOIL-engineered for today's sophisticated engines. Advanced synthetic technology resists chemical breakdown for maximum wear protection (and peace of mind) well beyond the traditional 3,000-mile oil change interval.
