ExxonMobil has announced two changes to its premium line of Mobil Delvac heavy-duty engine oils this October. A new formulation of the company's “Million Mile Oil,” Mobil Delvac 1300 Super 15W-40 was developed to meet the API CJ-4 spec, required for '07 engines.
Mobil Delvac 1300 Super will exceed category requirements for soot control, wear protection, oil consumption and deposit control, according to ExxonMobil. It will also be backward-compatible, meeting the older API CI-4 and CI-4 Plus requirements, while delivering significant performance enhancement, according to the oil maker.
“With new U.S. Environmental Protection Agency emissions regulations for heavy-duty vehicles taking effect in 2007, diesel engine oil performance requirements will become more stringent,” said Douglas Pond, commercial vehicle lubricants advisor-Americas, ExxonMobil Lubricants & Specialties. “In over 7-million miles of...testing, the new Mobil Delvac 1300 Super formulation delivered exceptional results, giving us great confidence to bring it to market as a cutting-edge CJ-4 product for 2007 engines using aftertreatment devices.”
Pond also said that fleets using reformulated Mobil Delvac 1300 Super “will be able to maintain current drain intervals for older engines using diesel fuel with either 15-ppm or 500-ppm sulfur content.”
The company also plans to introduce a new Mobil Delvac product this fall, MX 15W-40, which is expected to exceed the API CI-4 Plus spec.
