Chevron has introduced a pair of new CJ-4 compliant heavy duty diesel engine oils offering backwards compatibility and improved performance.
Chevron RPM LE 15W40 and Texaco Ursa Super Plus EC 15W40 meet previous CI-4 Plus specifications and carry the CAT ECF-3 approval.
Both oils reflect the changes the diesel industry is making in engine design, based on lower-sulfur content fuels and the need for better wear protection and anti-oxidation chemistry. Company officials say these products offer competition to so-called "premium brands."
