SUPER-D® 3 DIESEL ENGINE OIL 20W-50
Universal Fleet Engine Oil
Kendall® Super-D 3 Diesel Engine Oil is a high-quality SAE 20W-50 universal fleet engine oil designed for use in on-highway diesel trucks, off-highway diesel equipment, passenger cars and light trucks with diesel or gasoline engines operating in moderate to hot climates.
With advanced additive technology, Super-D 3 SAE 20W-50 provides engines with outstanding wear protection, soot control, and bearing corrosion protection. Because Super-D 3 has excellent soot dispersancy, it excels at protecting engines from soot-induced oil thickening and ensures low-temperature pumpability. Additionally, Super-D 3’s high dispersancy detergency and high alkaline reserve (TBN) help protect engines used in extended drain and severe service intervals.
Super-D 3 SAE 20W-50 meets or exceeds the performance requirements of API Service Categories CH-4 and SL. Though Super-D 3 is recommended for use in newer, low-emission diesel engines, it is backward serviceable in applications that require API CG-4 or earlier "C" category engine oils.
