Mobil Delvac XHP LE 10W-40 

Mobil Delvac™ XHP LE 10W-40

Mobil Delvac XHP LE 10W-40 is a synthetic extra high performance diesel engine oil engineered to provide lubrication to modern, high performance, low emissions engines used in severe on-highway applications. This engine oil is designed using the high performance base oils which provide excellent low temperature fluidity, high temperature viscosity retention, volatility control and contribute to potential fuel economy improvement. The new advanced additive system has been expertly engineered to help prolong the life and maintain the efficiency of emission reduction systems such as the Diesel Particulate Filter (DPF). The DPF is used by several truck builders to fulfill emission requirements of Euro IV and Euro V.

High output, low emission engines significantly increase demands on engine lubricants. Tighter engine design, use of inter-coolers, and turbochargers increase thermal stresses on the lubricant. Low emission engine technologies such as higher fuel injection pressure, retarded timing and aftertreatment devices all require improved oil performance in areas such as oxidation stability, soot dispersancy, volatility and compatibility with aftertreatment devices. The advanced technology in Mobil Delvac XHP LE 10W-40 delivers exceptional performance and protection of exhaust systems fitted with Diesel Particulate Filters (DPF). The key benefits include:


Advantages and Potential Benefits
