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 CJ-4, CI-4 PLUS and CH-4 service categories as well as key Original Equipment Manufacture (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 Diesel, Mack, Mercedes Benz, Navistar, Volvo, and others. Mobil Delvac MX ESP 15W-40 also meets or exceeds the requirements of the API SM specification for gasoline engines and mixed fleets.


Features and Benefits

Mobil Delvac MX ESP 15W-40 is formulated with Trimer additive technology 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 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:


FeaturesAdvantages and Potential Benefits
Superior soot-viscosity control Greater engine efficiency, long engine life and long oil life
Outstanding thermal and oxidative stability Reduced low temperature sludge build-up and high temperature deposits
Excellent oil consumption control Lower oil costs due to less make-up oil during operation
Excellent TBN reserves Improved corrosion protection and extended drain intervals
Stay-in-grade shear stability Maintains viscosity in severe, high temperature service for greater wear protection and long engine life
Excellent low temperature pumpability Faster oil flow and reduced 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



       Recommended by ExxonMobil for use in:

  • The latest low-emissions, high performance diesel applications equipped with aftertreatment systems using Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) technologies.
  • High-performance diesel applications including turbo-charged designs featuring EGR Technology and diesel applications using older, naturally aspirated conventional designs.
  • On-highway heavy-duty trucking and off-highway including: construction, mining, quarrying, and agriculture.
