Exceeding All Requirements

In June, Chevron was the first to announce that its new diesel engine oils, including Delo(R) 400 LE(TM) (Low Emissions) Multigrade SAE 15W-40 and Texaco Ursa(R) Premium TDX EC(TM) (Emission Control) SAE 15W-40 had passed all American Petroleum Institute (API) and U.S. original equipment manufacturer (OEM) tests required to meet the new API CJ-4 diesel engine oil specification.

Delo and Ursa API CJ-4 oils exceed the performance standards of the current API specification, CI-4 Plus, specifically in areas of wear control for valve-train, bearing and ring-liners, oxidation control, soot dispersancy, piston deposit control and oil consumption control. The company's new API CJ-4 oils also offer improved performance for existing and 2007 engines operating on ultra low sulfur diesel (ULSD).

Supporting Two Specifications

In March, Chevron was the first to announce it is offering 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.
