Description
Product Description
Mobil Delvac Modern 15W-40 Super Defense is an extra high performance diesel engine oil that provides excellent lubrication of today’s diesel engines promoting long engine life. As a result, this product meets or exceeds the specifications of major European and American engine manufacturers. 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 15W-40 Super Defense is also biodiesel compatible*, it 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 15w-40 and can be used as a replacement of same
*based on CEC L-109-14 (test modified with palm B100), meeting the limits in ACEA E7-16.
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 15W-40 Super Defense is formulated from high performance base oils and a balanced additive system to provide optimum engine performance in modern diesel and gasoline engines as well as older models. The key benefits include:
| Features | Advantages and Potential Benefits |
| High thermal and oxidation stability | Reduced sludge build-up, deposits and viscosity increase |
| TBN reserves | Deposit control and acid neutralisation |
| Stay-in-grade shear stability | Wear protection and viscosity control |
| High detergency/dispersancy | Clean engines and long component life |
| Improved soot handling | Improved viscosity control and used oil pumpability |
| Excellent low temperature properties | Start-up wear protection |
| Component compatibility | Long gasket and seal life |
| Meets demanding specifications of key OEMs | One engine oil for mixed fleet operations |
