Mobil 120645

Mobil Delvac 1 LE 5w-30 is a fully synthetic heavy duty diesel engine oil that is well suited for a broad range of modern low emission vehicles in a variety of applications. It offers advanced engine protection, emissions system protection and extended drain capability, as well as improved fuel economy relative to conventional 15w-40 engine oil.

Mobil Delvac 1 LE 5w-30 meets or exceeds a broad range of industry and manufacturer's specifications, including on- and off-highway commercial diesel-powered vehicles in the transportation, construction, mining and agricultural sectors.

Product Data Sheet

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.
