Mobil Delvac™ XHP Ultra 5W-30

Mobil Delvac XHP Ultra 5W-30 is a synthetic, extra high performance diesel engine oil engineered to provide outstanding protection and fuel economy for modern heavy duty diesel engines used in severe on highway applications.

This diesel engine oil is designed using advanced technology base oils which provide excellent low temperature fluidity, high temperature viscosity retention, volatility control, and contribute to potential fuel economy improvement. These base oils also feature an advanced additive system, which provides a high level of protection to all parts of the engine.


High output, low emission diesel engines significantly increase the demands on engine lubricants.  Tighter engine designs reduce oil consumption, resulting in less fresh oil make-up to replenish depleted additives.  Thermal stresses on the lubricant are increased with the use of intercoolers 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 Ultra 5W-30 delivers exceptional performance and is approved as the initial fill for Mercedes Benz Actros diesel engines.  The key benefits include:
