The latest synthetic engine oil for the newer low sulfur engines and equipment. DEO 5W-40 maintains the complete cold and hot temperature ranges as well as wear characteristics as the previous versions. DEO is backward compatable with all pre 2007 diesel engines and replaces previous 5W-40, 10W-40 and 15W-40 viscosity oils. It provides extraordinary lubrication with the latest base stocks and additives withstanding heat stress, soot, acids, deposits and corrosion during winter or summer use. This oil pours when cold and stays around longer during those heavy hauls earning the lowest volitility numbers in the market.

 The premium choice  for 2007 and newer heavy duty truck engines requiring API CJ-4 emission standards. Withstands the stress of heat, soot and acids to help prevent deposits corrosion and wear.

Broard viscosity range offers superior protection over a wide temperature range. Recommended for the longest service interval established by the engine, vehicle or equipment manufacturer. Drain intervals maybe extended beyond based on engine oil analysis. Extended service life of all exhaust treatment devices and particulate filters. Backward compatible with pre -2007 engines- replacing 5W-40, 10W40, and 15W40 weights.
