SHIELD® CLASSIC

CONVENTIONAL PASSENGER CAR ENGINE OIL

Phillips 66® Shield Classic Motor Oil, SAE 20W-50 is a high-quality, conventional automotive engine oil recommended for use in gasoline-fueled passenger cars and light trucks operating under high-temperature conditions, such as towing heavy loads, where the vehicle manufacturer specifies an SAE 20W-50 engine oil. It also may be used in
gasoline-fueled competition engines and high-performance street engines where
SAE 20W-50 engine oil is preferred. It provides engine protection for both turbocharged gasoline direct injection and conventional gasoline-fueled and flex-fueled passenger cars and light trucks under all operating conditions. It is not recommended for use in new cars under warranty.
