AMSOIL for diesel trucks
Diesel pickups and heavy-duty trucks depend on more than engine oil. This page organizes the main AMSOIL categories for engine, fuel system, filtration and drivetrain maintenance.
Build the maintenance plan around the whole truck
Start with the correct diesel engine oil, then look at fuel-system care, filters, transmission fluid and differential gear oil. The exact products depend on your engine, transmission, axle specifications and operating conditions.
Diesel Additives
Products for injector cleanliness, lubricity, cetane and cold-weather fuel concerns.
Filters
Find oil, air, fuel and heavy-duty filtration options.
Transmission Fluid
Match the fluid to your specific transmission requirements.
Gear Oil
For differentials and gearboxes that work under towing and hauling loads.
Heavy-duty commercial trucks
For buses, commercial trucks and other heavy-duty on-road applications, AMSOIL provides a dedicated lookup path separate from the light-truck guide.
