Chevron Products Co. announced that its diesel engine oils, including Delo, Ursa and RPM, now meet the new API CJ-4 diesel engine oil service category. According to Chevron, these oils “offer improved performance for existing and 2007 engines operating on ultra low sulfur diesel (ULSD).”

“API CJ-4 is the most robust API oil category ever developed for diesel engine,” said Jim McGeehan, global manager of diesel engine oil technology for Chevron Global Lubricants. “The new category includes nine fired engine tests and six bench tests. Chevron and Texaco products provided excellent performance in all these tests thanks to our advanced additive technology and Group II base stock. With CJ-4 testing behind us, our attention is now firmly fixed on PC-11 and the 2010 emissions regulations.”

The CJ-4 products, to be known as Delo 400 LE (Low Emissions) Multigrade SAE 15W-40, Texaco Ursa LA (Low Ash) SAE 15W-40 and Chevron RPM LA (Low Ash) SAE 15W-40, will be available October 15, 2006.

Chevron will offer both CJ-4 and CI-4 Plus versions of its diesel engine oils.
