Pennzoil Long-Life® Gold Diesel SAE 15W-40 Motor Oil provides premium quality service in both diesel (with API CH-4 or lower requirement) and gasoline engines (with API SL or lower requirement), and are specially formulated for heavy-duty diesel engines operating both on and off highways. Newly designed low emission diesel engines actually tend to produce more soot. However, this soot is captured in the engine oil and does not go out to the exhaust.
Pennzoil Long-Life® Gold Diesel SAE 15W-40 Motor Oil contains the latest development in dispersant technology to resist oil thickening caused by this soot. The dispersant minimizes sludge formation and effectively keeps particles in suspension to extend filter life.
Pennzoil Long-Life® Gold Diesel SAE 15W-40 Motor Oil is universal oil. It is recommended for all trucks and off-road diesel engines (such as heavy duty construction equipment, mining equipment, oil field engines, diesel powered coastal vessels, generator sets and farm equipment. It is ideal for mixed-fleet operation as it enables using only one oil for both diesel and gasoline engines. Always refer to the vehicle’s manual for the correct viscosity choice.
