Mobil Delvac MX MX™ 15W-40 Extra High Performance Diesel Engine Oil

Mobil Delvac MXTM

15W-40

Extra High Performance Diesel Engine Oil

For excellent lubrication of today's diesel engines

Mobil Delvac MX 15W-40 is formulated from high performance base oils and a superior balanced additive system to provide optimum engine performance in modern diesel and gasoline engines, as well as older models. Proven in the field in a wide variety of industries, applications, and mixed fleets, this extra high performance lubricant combines a blend of high performance base stocks with a progressive additive system to provide superior control of oil thickening and outstanding resistance to oxidation, corrosion, and high temperature deposits.

Key Features & Potential Benefits

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. Top piston fire rings are located higher on the piston bringing the oil film closer to the combustion chamber where higher temperatures increase thermal stress on the lubricant. Increased fuel injector pressure and retarded timing improve fuel burn efficiency, but also increase engine temperatures and increase soot loads. Mobil Delvac MX 15W-40 is formulated from high performance base oils and a superior balanced additive system to provide optimum engine performance in modern diesel and gasoline engines as well as older models. The key benefits include:
