Liberty Oilfield Services provides specialized stimulation services that help optimize well production. Operating a fleet of 100 service units powered by MTU engines, the company wanted to identify a solution that could enhance fleet efficiency and productivity. To help achieve this, the company approached ExxonMobil to identify a lubricant solution capable of extending oil drain intervals and reducing oil consumption.


After conducting an optimization study, ExxonMobil engineers recommended the company use Mobil DelvacTM Extreme 15W-40 high performance diesel engine oil. A premium synthetic blend diesel engine oil formulated with a boosted additive system**, Mobil Delvac Extreme 15W-40 diesel engine oil provides excellent wear protection and exceptional oxidation stability*** that can help operators improve performance for up to double OEM recommended ODIs****. In addition, ExxonMobil engineers recommended implementing routine Mobil ServSM Lubricant Analysis to monitor oil and engine condition once oil drain intervals are extended.


After using Mobil DelvacTM Extreme 15W-40 diesel engine oil, Liberty Oilfield Services safely extended oil drain intervals across its fleet from 750 hours to 1,500 hours and reduced oil consumption by 10,400 gallons. As a result, the company experienced enhanced productivity and safety benefits, generating company-estimated savings of US $135,200.
