Pennzoil Long-Life® Diesel Turbo SAE 20W-50 Motor Oil provides premium quality service in both diesel (with API CF-4 or lower requirement) and gasoline engines (with API SG 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® Diesel Turbo SAE 20W-50 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® Diesel Turbo SAE 20W-50 Motor Oil is recommended for both on and off-road heavy duty applications that require up to API CF-4/SG Service levels. Always change oil as specified by engine manufacturer to maintain your warranty.
