ang bilis kasi na over shadow ang CI-4 plus nang CJ-4....

minadali kasi yung Oil category na toh for the fast changing emission regulations which the engine manufacturers can't cope with.... it was designed in parallel during the development of many engines, so nung natapos design nung mga engines, the oil category is now late for emission standards...

CI-4 plus is definitely created and intended to extend oil change and improve soot handling on engines requiring that specification.
