Mobil Delvac MX III 20W-50
Extra High Performance Diesel Engine Oil
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:
Features | Advantages and Potential Benefits |
High thermal and oxidation stability | Helps to reduce sludge build-up, deposits and viscosity increase |
TBN reserves | Helps to control deposit and acid neutralization |
Stay-in-grade shear stability | Wear protection and viscosity control |
Advanced detergency/dispersancy | Helps to guarantee clean engines and long component life |
Improved soot handling | Helps to improve viscosity control and used oil pumpability |
Excellent low temperature properties | Start-up wear protection |
Component compatibility | Long gasket and seal life |
