Engineered for pre-2007 diesel engines in on-road applications as well as all model year diesel engines in off-road applications. High 12 TBN controls acids from combustion blow-by and EGR. Additives control soot thickening, oxidation and wear. Extended drain capabilities reduce downtime and motor oil expenses.

Engineered for pre-2007 diesel engines in on-road applications as well as all model year diesel engines in off-road applications. Also engineered for all gasoline engines recommending API SL specifications including turbo-charged vehicles. Provides superior wear protection and fuel efficiency.

For use in both diesel and gasoline engines. Ideal for applications where the extra protection of a higher-viscosity oil is desired. The higher viscosity may help reduce motor oil consumption in equipment experiencing higher than normal oil usage rates while running lower viscosity lubricants.

For use in both gasoline and diesel engines. Offers multi-functionality and wear protection. Ideal for applications where the extra protection of a higher-viscosity oil is desired. Excellent for motor homes and older vehicles, as well as many types of modern equipment and compatible with some motorcycles.
