Mobil Delvac MX™ ESP 15W-40
Product Description
Mobil Delvac MX™ ESP 15W-40 is an extra high performance diesel engine oil that helps extend engine life in the most severe on and off-highway applications while delivering outstanding performance in modern, high-output, low-emission engines including those with Exhaust Gas Recirculation (EGR) and Aftertreatment Systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs). Fully backwards compatible, Mobil Delvac MX ESP 15W-40 will also deliver the same exceptional performance in older conventional engines. As a result, it meets or exceeds the requirements of the API CK-4, CJ-4, CI-4 PLUS and CH-4 service categories as well as key Original Equipment Manufacturer (OEM) requirements.
Mobil Delvac MX ESP 15W-40 is the result of extensive cooperative development work with major OEMs and is recommended by ExxonMobil for use in a wide range of heavy duty applications and operating environments found in the trucking, mining, construction, quarrying, and agricultural industries. This product provides outstanding protection in the most demanding diesel engines of Caterpillar, Cummins, Detroit, Deutz, Mack, Mercedes Benz, Renault, MAN, Navistar, Volvo, and others. Mobil Delvac MX ESP 15W-40 also meets or exceeds the requirements of the API SN / SM / SL specifications for gasoline engines and mixed fleets. Mobil Delvac MX ESP 15W-40 is biodiesel compatible.*

Features and Benefits
Mobil Delvac MX ESP 15W-40 is formulated and a mixed detergent system to deliver cutting-edge performance in both new and older engines. In addition to assuring excellent control of oil thickening due to soot build-up and outstanding TBN retention for long drain intervals, Mobil Delvac MX ESP 15W-40’s advanced technology also provides outstanding resistance to oil consumption, oxidation, corrosive and abrasive wear, and high temperature deposits.
The key benefits include:
| Features | Advantages and Potential Benefits |
| Superior soot-viscosity control | Helps to maintain engine efficiency, long engine life and long oil life |
| Outstanding thermal and oxidative stability | Helps to reduce low temperature sludge build-up and high temperature deposits |
| Excellent oil consumption control | Helps to lower oil costs due to less make-up oil during operation |
| Excellent TBN reserves | Helps to improve corrosion protection and to extend drain intervals |
| Stay-in-grade shear stability | Helps to maintain viscosity in severe, high temperature service for greater wear protection and long engine life |
| Excellent low temperature pumpability | Fast oil flow and helps to reduce wear during engine start-up in low temperatures |
| Superb resistance to corrosive and abrasive wear. | Long life of critical wear surfaces |
| Component compatibility | Long gasket, seal, and after treatment (DPF and DOC) life |
| Meets demanding specifications of key OEMs and latest API gasoline service category | One engine oil for mixed fleet operations |
Applications
