Valvoline's Premium Blue SAE 15W-40 engine oil, endorsed and recommended by Cummins Inc for its heavy-duty diesel engines, exceeds 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.
Premium Blue engine oil is designed to provide advanced lubricant performance in emissions treatment systems equipped with emissions control hardware, including exhaust gas recirculation (EGR), diesel particulate filters (DPF), and Caterpillar ACERT technology.
This oil also meets 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. With Premium Blue, engine manufacturers’ recommended drain intervals can be maintained in pre-2007 engines with the use of low or ultra-low sulfur diesel fuel. Premium Blue users can still have the Cummins-approved extension of standard drains for Cummins ISX and ISM engines.
