Description
Features and Benefits
Mobil Delvac MX ESP 15W-40 is formulated using Synthetic Technology and an optimised additive system that delivers excellent 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.
Up to 80% improved high-temperature viscosity control and 50% improved oxidation resistance1 |
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.
Wear protection is 20% better2 |
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 API gasoline service categories | One engine oil for mixed fleet operations |
