Chevron Products Co.’s new Chevron RPM LE SAE 15W-40 and Texaco Ursa Super Plus EC SAE 15W-40 heavy duty diesel engine oils meet both API CJ-4 and CI-4 Plus specifications, and replace the CI-4 Plus-only versions.

Both products are CAT ECF-2 approved and the new formulation adds CAT ECF-3 approval. The motor oils will be on sale nationwide in bulk in January with a full transition by March.

"The market is ready for the shift. With 95% of the country's heavy-duty vehicles operating on ultra low sulfur diesel (ULSD) it makes sense to offer engine oil with improved performance in these conditions for new as well as older engines," said Nicole Fujishige, business sector manager for Chevron Products Company.  "Customers will now have an oil that provides better anti-oxidation and anti-wear performance along with enhanced deposit control at a lower price point than premium brands."
