ExxonMobil Responds

ExxonMobil reached out to JobbersWorld this afternoon with a statement regarding a claim JobbersWorld reported on last Friday; a claim made by Shell saying that a sample of Mobil Delvac 1300 15W-40 CK-4 Shell examined “does not meet the minimum API CK-4 requirements or the Volvo/Mack or Cummins OEM requirements.” Shell Claims Shell Rotella Meets The Standards While A Leading Diesel Engine Oil Does Not

With regards to Shell’s claim, ExxonMobil says:

“ExxonMobil stands by the quality of our products and has re-affirmed for our distributors and customers that Mobil Delvac 1300 Super 15W-40 carries valid OEM approvals and API CK-4 licensing. In addition, Volvo has confirmed that the Volvo VDS-4.5 and Mack EOS-4.5 approvals for Mobil Delvac 1300 Super 15W-40 remain intact based on the fully compliant data set originally submitted, which includes passing the Volvo T-13 engine test results for oxidation and viscosity increase at the more stringent Volvo limits. Beyond valid API licensure and OEM approvals, Mobil Delvac 1300 Super and Mobil Delvac Super FE have proven on-road performance in ExxonMobil controlled field trials utilizing 69 representative trucks accumulating 23 million miles. ExxonMobil cannot address the specifics of the test results Shell produced, because we do not have the data, but we are conducting a thorough investigation.”
