Mobil Delvac Modern™ 20W-50 Super Defense
Synthetic Technology Commercial Vehicle Engine Oil
Mobil Delvac Modern™ 20W-50 Super Defense is an extra high performance diesel engine oil that provides excellent lubrication of today's diesel engines promoting long engine life. It is recommended by ExxonMobil for use in a wide variety of industries, applications, and mixed fleets.
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 Modern 20W-50 Super Defense combines a blend of high performance base stocks with a progressive additive system to provide superior control of oil thickening due to soot build-up and high temperatures as well as outstanding resistance to oxidation, corrosion, and high temperature deposits.
This product is fully compatible with Mobil Delvac MX 20W-50 and can be used as a replacement of same.

Synthetic Technology Commercial Vehicle Engine Oil
Features and 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 Modern 20W-50 Super Defense is formulated from high performance base oils and a balanced additive system to provide optimum engine performance in modern diesel engines as well as older models.
