Full synthetic 15w-40 diesel engine oil with Triple Protection Plus technology protects against wear, oil breakdown, deposits, and improves low-temperature flow. Exceptional wear protection for longer life in a wide range of heavy-duty engine applications — from pickup trucks to tractors to semi rigs.
Increased shear stability for better viscosity control and optimal engine oil pressure. Enhanced fuel economy capability of 1. 5 percent without compromising engine protection or durability compared to 15W-40 oils. Multi-functional dispersant additives provide an enhanced level of protection against the effects of soot, dirt, and other contaminants compared to previous formulation.


Recommended for use in all super high-performance diesel applications, including low emission engines.



Engineered to provide exceptional performance in engines operating under severe service conditions including towing and hauling under high temperatures.

Controls engine wear 37 percent better than the maximum wear requirements in API CK-4 engine wear tests. Ideal for on-highway fleets, and agricultural machinery, construction, and diesel pickup trucks — including high-power vehicles that require resistance to heat and stress.
