Mobil Delvac 1™ LE 5W-30

Delvac_1LE5W30Mobil Delvac 1™ LE 5W-30 utilizes state-of-the-art technology to deliver exceptional performance and is well suited for an extensive array of diesel-powered commercial vehicles for both on- and off-highway use in industries such as transportation, mining, construction and agriculture.  Mobil Delvac 1 LE 5W-30 meets or exceeds an extremely broad range of industry and manufacturer specifications from around the world.

High output, low emissions engines significantly increase demands on engine lubricants. Tighter engine design reduces oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Thermal stresses on the lubricant are increased with the use of inter-coolers and turbochargers. Higher fuel injection and cylinder pressures and retarded timing improve burn efficiency, but also increase engine temperatures, volatility, and soot loading of the oil. The advanced technology in Mobil Delvac 1 LE 5W-30 delivers exceptional performance in these severe conditions while protecting emissions systems.
