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 ex-fueled passenger cars and light trucks under all operating conditions. It is not recommended for use in new cars under warranty. Shield Classic Motor Oil is formulated to provide excellent wear protection, to minimize the formation of sludge and varnish, and to resist viscosity and thermal breakdown, even in severe service. It also protects against rust and bearing corrosion and is resistant to foaming.
