ExxonMobil has announced two changes to its premium line of Mobil Delvac heavy-duty engine oils. The company will introduce a new formulation of its "Million Mile Oil," Mobil Delvac 1300 Super 15W-40, in October to meet the API (American Petroleum Institute) CJ-4 diesel engine oil specification. At the same time, ExxonMobil said it will introduce a new product to its Mobil Delvac line, Mobil Delvac MX 15W-40, which will exceed the API CI-4 Plus specification (www.mobildelvac.com).
The new formulation of Mobil Delvac 1300 Super 15W-40 will exceed category requirements for soot control, wear protection, oil consumption and deposit control, according to ExxonMobil. The new formulation will also be backwards compatible, meeting the requirements of API CI-4 and CI-4 Plus, while delivering significant performance enhancement compared to API CI-4 Plus technology.
"With new U.S. Environmental Protection Agency emission 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 seven million miles of extensive field 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 after-treatment devices. With reformulated Mobil Delvac 1300 Super, our customers can also have the peace of mind that they will be able to maintain current drain intervals for older engines using diesel fuel with either 15 ppm or 500 ppm (parts-per-million) sulfur content.”
