Upgraded Protection For Diesel Power
You paid extra for the diesel power needed to hook onto the heavy stuff.
AMSOIL synthetic technology helps you get your money’s worth of power and fuel efficiency for years to come. We built our diesel oils from the ground up. They handle soot and provide more advanced protection against wear and oil consumption compared to conventional lubricants. Combined with premium fuel additives that keep high-pressure injectors clean and lubricated, AMSOIL synthetic lubricants provide complete protection and performance through the life of your truck.
During heavy use and even abuse, AMSOIL synthetic lubricants provide your work truck maximum protection, even when you need to stretch the miles between oil changes to get the job done.
AMSOIL synthetic diesel oils provide outstanding wear protection while resisting oil consumption, helping hard-working diesel engines last longer. They withstand high-temperature breakdown to help prevent harmful deposits from forming while remaining fluid in sub-zero temperatures for easier cold starts and fast circulation.
AMSOIL premium protection eliminates the worry associated with occasional overdue oil changes and enables independent business owners to confidently finish the job.
Independent testing shows AMSOIL Heavy-Duty Synthetic Diesel Oil delivers 4X more protection against wear than required by Detroit Diesel’s standard*. In the same test, AMSOIL Signature Series Max-Duty Synthetic Diesel Oil provides 6X more wear protection than required by the standard*.
