Bancroft & Sons is a Federal Motor Carrier operating throughout the United States that specializes in mail hauling. Priding itself on its reliable service, the company recognizes the importance of enhancing productivity and keeping its fleet of 184 trucks on the road for as long as possible. In an effort to further enhance productivity, the company approached ExxonMobil to identify a lubricant solution capable of extending oil drain intervals.


After assessing fleet details and conducting a full oil drain interval optimization assessment, ExxonMobil engineers recommended switching to Mobil DelvacTM 1300 Super 10W-30 heavy duty diesel engine oil. Formulated with a blend of high quality basestocks and a tailored additive system that helps deliver excellent wear protection and outstanding oxidative stability, Mobil Delvac Super 1300 10W-30 diesel engine oil is designed to deliver robust engine protection in severe conditions seen throughout the United States. In addition, ExxonMobil engineers recommended implementing routine Mobil ServSM Lubricant Analysis to monitor engine and oil condition.


After converting all 184 of its vehicles to Mobil Delvac 1300 Super 10W-30 diesel engine oil, Bancroft & Sons experienced extended oil drain intervals from 40,000 miles to 60,000 miles, as well as reduced oil consumption. As a result, the company was able to improve productivity and enhance operational efficiency, generating company-estimated savings of US $127,328.
