Mobil Delvac MX III 20W-50

Extra High Performance Diesel Engine Oil

Mobil Delvac MX III 20W-50

Mobil Delvac MX III 20W-50 is an extra high performance diesel engine oil that provides excellent lubrication of today's diesel engines promoting long engine life. This extra high performance has been proven in the field in a wide variety of industries, applications.

 

The advanced chemistry of this product provides outstanding performance in both modern, demanding low-emission diesel engines and older diesel engines operating on low or high sulphur fuel. Mobil Delvac MX III 20W-50 combines a blend of high performance base stocks with a balanced additive system to provide excellent control of oil thickening due to soot build-up and high temperatures as well as outstanding resistance to oxidation, corrosion, and high temperature deposits.

 

Features and Benefits

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 and retarded timing require improved oil performance in areas such as oxidation stability, soot dispersancy, and volatility. Mobil Delvac MX III 20W-50 is formulated from high performance base oils and a balanced additive system to contribute to optimum engine performance in modern diesel and gasoline engines as well as older models. The key potential benefits include:
