Thread: Diesel injector cleaner additive ?

White smoke is incomplete combustion or sometimes lack of compression. If the incomplete combustion is due to tired / faulty glow-plugs, (especially if it only happens when cold), then double-glow it before starting and see if the problem persists.

If your injectors are worn, a cleaner wont do anything. Needs springs replacing, break pressure resetting and ideally new nozzles too.
