SAE 15W-40 Heavy-Duty Diesel and Marine Oil

15w-40 synthetic oil

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.

Series 3000 5W-30 Synthetic Heavy Duty

5-w30 synthetic diesel oil

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.

10W-30/SAE 30 Synthetic Heavy-Duty Diesel Oil

Exceeds both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Provides outstanding performance in pre-2007 diesel engines in on-road applications as well as all model-year diesel engines in off-road apps. Also recommended for gasoline engines requiring API SL or previous specifications.

Premium Protection 20W-50 Synthetic Motor Oil

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.
