Mobil Delvac Modern 15W-40 Super Defense V4 is a high performance synthetic-technology diesel engine oil that provides excellent lubrication of today's diesel engines and promotes long engine life, meeting or exceeding the requirements of virtually all major European and American engine manufacturers. Its chemistry delivers excellent performance in both modern, demanding low-emission diesel engines and older diesel engines operating on low- or high-sulfur fuel, combining high-performance base stocks with a balanced additive system for excellent control of oil thickening from soot build-up and high temperatures, together with resistance to oxidation, corrosion and high-temperature deposits. It is recommended for naturally aspirated and turbocharged diesel-powered equipment from leading Japanese, European and American manufacturers, on-highway light and heavy-duty trucking, off-highway construction, mining, quarrying and agriculture, and mixed fleet applications. Key benefits include high thermal and oxidation stability, TBN reserves for deposit control and acid neutralization, stay-in-grade shear stability, advanced detergency/dispersancy, and improved soot handling. It meets or exceeds ACEA E7, API SL/SJ/CH-4/CI-4, MTU Oil Category 2, Ford WSS-M2C171-D and Caterpillar ECF-2, with approvals including Mack EO-N, Mack EO-M Plus, RENAULT TRUCKS RLD-2, VOLVO VDS-3 and Cummins CES 20076/20077.
