Chevron Products Co. has announced its diesel engine oils — including Delo, Ursa and RPM — have passed all American Petroleum Institute and U.S. original equipment manufacturer tests required to meet the new API CJ-4 diesel engine oil specification. The company says its new API CJ-4 oils offer improved performance for existing and 2007 engines operating on ultra-low-sulfur diesel.

“Delo, Ursa and RPM heavy-duty diesel engine oils are ready for API CJ-4 and can be launched on October 15th, 2006, when the API license is granted,” says Jim McGeehan, global manager of diesel engine oil technology for San Ramon, Calif.-based Chevron Global Lubricants. “API CJ-4 is the most robust API oil category ever developed for diesel engines. 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.”

To meet the new API CJ-4 specification, Chevron tested its new Delo, Ursa and RPM oils with key engine manufacturers. The company also is preparing for future emissions regulations by testing aftertreatment systems designed for use in 2010 with a global engine manufacturer.

Chevron says its new 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 — have completed and exceeded all the requirements for:

  • API CJ-4, CI-4 PLUS, CI-4, CH-4, CF and SM;
  • Caterpillar ECF-3;
  • DDC Power Guard 93K218;
  • Cummins CES 20081;
  • Mack EO-O Premium Plus 07;
  • Volvo VDS-4; and
  • MB228.3.
  • Delo, Ursa and RPM API CJ-4 oils, according to Chevron, also exceed the performance standards of API CI-4 Plus oils, specifically in areas of:

  • Wear control for valve-train, bearing and ring-liners;
  • Oxidation control;
  • Soot dispersancy;
  • Piston deposit control; and
  • Oil consumption control.
  • Chevron previously announced in March that it will offer both an API CJ-4 and an API CI-4 Plus version of its diesel engine oils based on customer feedback and expected market demand. Although Chevron’s Delo, Ursa and RPM heavy-duty engine oils have passed all tests required to meet the new API CJ-4 heavy-duty diesel engine oil specification, CJ-4 products will not be officially licensed or available until October 2006.
