Mobil Delvac MX 1™ 5W-40 High Performance Heavy Duty Diesel Engine Oil

Mobil Delvac 1TM

5W-40

High Performance Heavy Duty Diesel Engine Oil

For outstanding diesel engine performance at high temperatures

Many modern, low emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for high performance lubricants. Mobil Delvac 1 5W-40 is a fully synthetic high performance heavy duty diesel engine oil maintains that delivers excellent performance in modern low emission engines and older, well-maintained engines.

Key Features & Potential Benefits

Many modern, low emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for high performance lubricants. Current tighter engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Top piston rings are located higher, bringing the oil film closer to the combustion chamber and exposing the lubricant to severe thermal stresses. Mobil Delvac 1 5W-40 maintains outstanding performance at high temperatures. It is also fully compatible with conventional oils. The key benefits include: 1 Relative to conventional 15W-40 engine oil. Actual fuel economy improvement is dependent on vehicle/equipment type, outside temperature, driving conditions and your current fluid viscosity
