15W-40 Diesel Motor Oil, Triple Protection Formula, 5 Gallon Pail

This diesel engine oil, formulated with a 15W-40 viscosity, delivers outstanding wear protection to extend the lifespan of a broad range of heavy-duty engines—from diesel pickup trucks and tractors to tractor-trailers. It employs advanced additive technology to ensure superior engine cleanliness throughout the oil drain interval, safeguarding against the harshest conditions found in both modern, low-emission engines and older, hard-working diesel engines. The 15W-40 formulation provides deposit control that maintains engine cleanliness for peak performance and longevity. It effectively supports the durability of emissions control systems in vehicles equipped with diesel particulate filters and after-treatment systems. Additionally, it offers enhanced protection against viscosity loss from shear and improved oil aeration compared to earlier versions. This product is an excellent choice for on-highway fleets, general hauling, construction, agriculture, public transport operators, and diesel pickup trucks, including high-power vehicles that require resistance to increased heat and stress.
