I agree, generally I don't think this will do anything noticeable on cars that already have a clean fuel system. Its very noticeable on cars with a dirty noisy fuel system like mine was. Although mine doesn't have high k's (87000) somehow the injectors got a bit dirty and noisy and this stuff seemed to clean them up pretty good and now drives a lot smoother and quieter.Be more effective on older cars with high kms
I just run mine under different loads. Air-con on and off, flick the fast idle switch and let it idle at around 1500rpm for a while. Give it a few good boot fulls, up to around 4000rpm and back to idle just to get the injectors fully open. The can usually runs for about 15 min, you could probably drive it around, but might be hard to stop it falling over that's all...Bought some liqui molly last week and getting a inline filter this weekend. Is it worth driving a round the block carefully vs just idling away in the street ? Stop it over heating or is this not really a issue?
