Diesel and Marine
AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is a premium diesel oil that provides excellent performance in all types of diesel engines where highly effective control of wear and deposits is vital. Engineered with heavy-duty dispersant/detergent additives, its Total Base Number (TBN) of 12 neutralizes acids and controls soot thickening from exhaust gas recirculation (EGR) and blow-by to protect against corrosion, cylinder bore polishing (wear), varnish and sludge deposits.
AMSOIL XL Synthetic Motor Oil for gasoline and diesel engines are the choice for those who want to do something extra for their vehicle. Its boosted formulation delivers extra cleaning power, outstanding wear control, excellent high- and low-temperature protection and exceptional fuel economy.
AMSOIL Heavy-Duty Synthetic Diesel and Gasoline Motor Oil are formulated for hard-working equipment. It is engineered to provide 4X better wear protection than required by the Detroit Diesel DD13 Scuffing Test for Specification DFS 93K222, giving you the edge to keep trucks and equipment operating at peak performance.
