Ang alam ko ung API CJ-4 lang ung hindi pwede but API CI-4 or CI-4 plus should be compliant with Innova Diesel. Paki clarify lang. Thanks.


CI-4

Status: Current

Introduced September 5, 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards implemented in 2002. CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation (EGR) is used and are intended for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4, CG-4, and CH-4 oils.

You will notice that the manual still recommends API CD or CE, both of which are really obsolete.

CI-4 should be compatible with the KD-FTV engines
