AMSOIL Motor Oils
AMSOIL Premium Synthetic Motor Oils are premium oils designed for those who demand the absolute best lubrication for their engines.
AMSOIL revolutionized the automotive world with its introduction of the first synthetic motor oil to meet American Petroleum Institute service requirements. Today, AMSOIL is the recognized leader in synthetic lubricant technology. With three premium synthetic motor oil lines available, everyone from casual motorists to hardcore performance enthusiasts can experience the many benefits of AMSOIL synthetics throughout the drain interval they prefer.
AMSOIL synthetic motor oils reduce friction, resulting not only in enhanced performance and protection, but helping increase fuel efficiency as well. With less resistance to internal moving parts, engines are able to operate at peak efficiency and deliver maximum mpg.
By controlling friction and heat more effectively than conventional oils, AMSOIL synthetic motor oils significantly reduce the rate of component wear and failure. During cold starts when most wear occurs, they remain fluid to circulate and deliver almost immediate lubrication to critical engine parts.
AMSOIL synthetic motor oils’ low coefficient of friction allows more energy to reach the vehicle’s wheels, maximizing power and performance. Their sophisticated chemistries reduce oil consumption and inhibit sludge formation for a cleaner, more efficient engine.
AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972.
Trust the extensive experience of AMSOIL - The First In Synthetics® to do the best job protecting your engine.
