hey all, just wondering if any of you have noticed something similar: i seem to be getting better gas mileage ( i was getting 10 l / 100km and now i'm getting around 7.5-8.0 l / 100km, both on highway ) after adding injector cleaning fluid ... i'm wondering if that's what made the difference... hmm i'm not a mechanic really so... the car is a civic 99... just broke 50000km on it..
