POWER-D® ENGINE OIL 15W-50
PREMIUM UNIVERSAL FLEET ENGINE OIL
Phillips 66® Power-D Engine Oil is a premium synthetic blend fleet engine oil suitable for on-highway diesel trucks, off-highway diesel equipment, passenger cars, and light trucks with either diesel or gasoline engines, making it great for mixed fuel type fleets. This universal engine oil offers excellent protection for EGR-equipped and older, non-EGR diesel engines.
This high-quality engine oil uses advanced additive technology to deliver exceptional wear protection, soot control, and bearing corrosion protection. With outstanding soot dispersancy, Power-D Engine Oil prevents abrasive wear and oil thickening, ensuring reliable low-temperature pumpability even in soot-laden conditions.
Power-D Engine Oil's high dispersancy-detergency and alkaline reserve (TBN) offer additional protection during extended drain or severe service intervals, particularly in EGR-equipped engines.
This engine oil meets or exceeds the performance requirements of API Service Categories CI-4 and SL, API CI-4 PLUS, and leading OEM specifications. It adheres to worldwide standards for diesel engine oils and is backward serviceable for use where API CH-4 or earlier "C" category engine oils are specified.
