Kendall® Super-D 3 Diesel Engine Oil, SAE 15W-40, is a premium quality universal  eet engine oil designed for use in on-highway diesel trucks and off-highway diesel equipment, as well as in passenger cars and light trucks with either diesel or gasoline engines. It is recommended for use both in EGR-equipped diesel engines and in older, non-EGR diesel engines. It also will provide excellent protection for gasoline engines for use in mixed commercial  eets. Super-D 3 SAE 15W-40 is formulated with advanced additive technology to provide outstanding wear protection, soot control and bearing corrosion protection. Outstanding soot dispersancy protects against abrasive wear and soot-induced oil thickening, and ensures good low-temperature pumpability even with soot-laden oil. High dispersancy-detergency and a high alkaline reserve (TBN) provide extra protection in extended drain or severe service intervals, and in EGR-equipped engines. Super-D 3 SAE 15W-40 meets or exceeds the performance requirements of API Service Categories CI-4 and SL, API CI-4 PLUS, and leading OEM speci cations and worldwide standards for diesel engine oils. It is backward serviceable for use where API CH-4 or earlier “C” category engine oils, or the concurrent earlier OEM speci cations, are speci ed.
