Mobil Delvac Modern 10W-40 Super Defense is a high performance engine oil with synthetic technology that provides excellent lubrication for today's diesel and gasoline engines operating in severe applications, keeping engines clean and promoting long engine life. It is recommended by ExxonMobil for European, Japanese and American engines, engineered with a blend of advanced technology base stocks and an additive system that gives a strong foundation for oxidation resistance, soot handling and wear control, supplemented with excellent piston-deposit protection and reduced sludge formation. Its viscosity and multigrade characteristics provide excellent cold cranking and oil pumpability at low temperatures. It is recommended for naturally aspirated and turbocharged diesel engines from European, Japanese and American manufacturers, on-highway light and heavy-duty trucking including mixed fleets with gasoline engines and cars, and off-highway mining, construction, quarrying and agriculture. Key benefits include increased thermal and oxidation stability, enhanced wear and corrosion protection, and enhanced low-temperature pumpability. The oil meets or exceeds API CH-4, CI-4, SJ and SL, and ACEA E7, and carries approvals including Mack EO-M Plus, Mack EO-N, MTU Oil Category 2, RENAULT TRUCKS RLD-2, VOLVO VDS-3 and Cummins CES 20077/20078/20076.
