Fully Synthetic Diesel Engine Oil specifically formulated for extended drain service in the most demanding applications requiring API CK-4 Service Category. It is also well suited for the latest
OEM EPA 2010 compliant on-highway and Tier 4 non-road diesel engines equipped with after treatment devices such as Diesel Oxidation Catalysts, Particulate Filters and Selective Catalytic
Reduction systems or previous model year diesel engines. Exceeds the highest API SN gasoline engine performance as well.

Blended with partial Polyalphaolefins (PAO) base stocks and a state-of-art additive package, the oil continues to provide long drain service in conventional engines by promoting longer engine life and reduced component wear by providing higher oil film thickness, better wear performance and improved oxidation control at higher temperatures. API CK-4 oils deliver improved soot-handling and shear stability performance in all engines.
