AMSOIL Synthetic Blend
15W-40 Diesel Oil

A blend of high performance synthetic base stocks, natural base stocks, and advanced additives. It provides outstanding performance and protection over extended drain intervals in light and heavy-duty diesel engines. Fuel efficient formula for both gasoline and diesel engines.

Extended drain capability reduces downtime and oil expenses. Twelve TBN formula fights corrosion. AMSOIL 15w-40 Blend resists oil breakdown in your engine from heat, blow-by chemicals and oxygen longer than conventional oils.

Reduces friction and drag so your engine will reduce fuel consumption while reducing wear and improving performance.
