Chevron Products Company’s API CJ-4 and API CI-4 PLUS heavy-duty diesel engine oils meet the new Caterpillar ECF-2 specification. As of March 1, Caterpillar recommends the use of ECF-2 for pre-2007 on-road and any off-road Caterpillar engines no bigger than the C3500.
Chevron’s CJ-4 oils already met the Caterpillar ECF-3 specification, designed for 2007 diesel engines fitted with diesel particulate filters that use 15 ppm ultra-low-sulfur diesel fuel. Meeting both the ECF-2 and ECF-3 specifications enables operators to implement a one-oil inventory strategy for pre-2007 and 2007 compliant Caterpillar on- and off-highway equipment, the company says.
