High output low emission engines significantly increased demands on engine lubricants. Tighter engine designs reduce 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 pressure and retarded timing improve burn efficiency but also increase engine temperatures volatility and soot loading of the oil. The advanced technology in Mobil Delvac XHP Extra 10W 40 delivers exceptional performance in both modern diesel engines as well as older models.

Mobil Delvac XHP Extra 10W 40 is a synthetic extra high performance diesel engine oil engineered to provide outstanding lubrication to modern high performance diesel engines used in severe on and off highway applications. This diesel engine oil is designed using high performance base oils which provide excellent low temperature fluidity high temperature viscosity retention volatility control and fuel economy improvement. These base oils are enhanced with an advanced additive system which provides a high level of protection to all parts of the engine. Mobil Delvac XHP Extra 10W 40 is engineered to provide long oil drain intervals in modern diesel engines.
