Hi, I have a 95 Diesel Corsa Isuzu engine-done 130K and its a bit lumpy and smokey on start up and I was told to put redex diesel in the tank to clean out the injectors but it hasnt made any diff. So as the car isnt worth enough to justify getting them cleaned professionally, I was told to pour Redex directly into the Fuel filter and start/turn over the engine to clean out the injectors....I know this sounds crude but as a DIY method is it worth doing/would it damage the engine?
Ive read that some people use 1 bottle for the filter another for the tank? is that too much? the forte is 400ml. I want to change the fuel filter at the same time and I was wondering if I should pour the stuff into the old filter and run the engine, then throw the filter and fit the new one? Or is it ok to put the stuff into the new filter?
And finally do these cleaners have long lasting effects? as I've seen most comments are to do with "quick fixes" for thr MOT Emission's test.
Would appreciate your comments
Mike
