A customer with a goal to reduce their total cost of ownership agreed to work jointly with Axion, an authorized ExxonMobil distributor, to implement an oil drain interval study in their engines using Mobil Delvac™ MX 15W-40 heavy-duty diesel engine oil.


The Axion engineers suggested using Mobil Delvac™ MX 15W-40 in conjunction with Mobil Serv℠ Lubricant Analysis to extend the drain interval of the engine oil from 250 to 500 hours. During the process, contamination levels were closely monitored to avoid wear from high silicon levels.


Oil drain intervals were extended by 100%, from 250 to 500 hours. Additionally, Mobil Serv℠ Lubricant Analysis results noted good oil performance and virtually no engine wear.

The customer reports that Mobil Delvac™ MX 15W-40 heavy-duty diesel engine oil has helped to increase availability of the equipment, reduce oil consumption and generate annual savings of more than US $1,400,000.

*This success story is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.

*Exxon Mobil shall include ExxonMobil alliance partners.
