Premium Blue meets API CJ-4 spec

Valvoline announced in October that its Premium Blue® SAE 15W-40 engine oil, endorsed and recommended by Cummins Inc. for its heavy-duty diesel engines, exceeds the requirements of the American Petroleum Institute (API) Service Category CJ-4 specification for use in high-speed four-stroke cycle diesel engines designed to meet U.S. 2007 model year on-highway exhaust emissions. According to Valvoline, Premium Blue is formulated to provide longer and better corrosion protection for all engine parts and to provide advanced soot control, as well as greater shear stability. Valvoline All-Fleet® Plus SAE 15W-40 and Premium Blue® Extreme full synthetic SAE 5W-40 will remain approved for API CI-4 Plus products until market conditions change. (October 24, 2006)
