Phillips 66® Power-D Engine Oil is a premium quality synthetic blend universal fleet 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 where the viscosity grade is appropriate. 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 in mixed commercial fleets.
