SUNOCO FLEET SAE 20W-50 DIESEL ENGINE OIL

SUNOCO FLEET SAE 20W-50 CH-4 ENGINE OIL is designed to meet the lubrication requirements of a variety of older diesel and gasoline fueled engines or vehicles operating in warmer climates. This oil can be used wherever API CH-4 or SJ lubricant is recommended or where a thicker film strength lubricant is desired.  SUNOCO FLEET SAE 20W-50 CH-4 ENGINE OIL is specially formulated to provide superior protection, resist oxidation and provide the higher viscosity needed in climates where temperature ranges are above 50 degrees year-round.

SUNOCO FLEET SAE 20W-50 CH-4 ENGINE OIL prevents sludge and varnish deposit build up on engine pistons, has good anti-foaming characteristics and excellent shear stability for lasting component protection.  Its superior composition resists thermal and oxidation breakdown due to high temperatures and protects against wear and corrosion at the highest levels.

SUNOCO FLEET SAE 20W-50 CH-4 ENGINE OIL can be used where any car, light duty truck, or heavy-duty diesel vehicles require a higher viscosity fluid to protect engine parts from high temperature conditions or heavy-duty service. It is also designed for applications where engines operate under extreme applications such as towing heavy equipment at high speeds over long distances.
