LEXINGTON, KY – Valvoline’s 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 2007-model year on-highway exhaust emissions. The new formulation will be backwards compatible and meet the requirements of API CI-4 Plus and CI-4 categories. Valvoline’s Premium Blue engine oil is designed to provide advanced lubricant performance in modern emissions treatment equipped with sophisticated emissions control hardware, including all types of exhaust gas recirculation (EGR), diesel particulate filters (DPF), and Caterpillar ACERT technology. 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. In addition to API CJ-4 performance, Premium Blue meets the requirements of Cummins CES 20081, DDC Power Guard 93K218, Mack EO-O Premium Plus ’07, Volvo VDS-4 and MB228.3, and the proposed CAT ECF-3. Due to market demand, 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. Valvoline All-Fleet Plus SAE 15W-40 has met the engine test requirements of API CJ-4.
