anyway if you use it too often how can you tell the difference from not using it at all, do you actually open your engine to check the valves etc...
i don't think so!
i would actually be worried to use stuff that are not as such recommended by car manufacturers, paint stripper sounds rough, like the lads before i think good quality fuel and a cleaner every so often is probably enough, and it makes sense to do it before an oil change too.
