civic mileage
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.. |

That does not suprise me. You should not calculate your gas mileage when products like injector cleaning fluid are mixed with the gas. Your vehicle is burning gas and the injector cleaning fluid with means you are using less gas than normal. |

The injector has to spray an exact amount of fuel for a few miliseconds, in a certain pattern, like your shower nozzle in the bath. If it won't open and close smoothly, or if it drips rather than delivering a perfectly metered blast of fuel, the effeciency of that cylinder drops off, sometimes worse at the higher revs. Yopu may have been driving a three-cylinder engine and not known it. I'm sure there are some GREAT web sites that explain injectors with graphics. Gummed up injectors can cause other problems that have been covered in this group, like finding your engine 'flooded' in the morning, and needing to hold the gas pedal down to get the engine to fire. The symptoms would seem to point to a bad main relay, but they aren't at all temperature related. The actual cause is an injector sticking open when the engine is shut off, and so the remaining pressure pumps a bunch of fuel into one cylinder until it's used up. Next morning, if you take the time to listen to the fuel pump, you'll hear it run for three or four seconds because it has to pressurize itself much longer than it should have too. Other side effects of a sticky injector are oil dilution and excessive cylinder wear because the rings are getting a bath in gasoline every night, and the fuel is dripping into the oil sump. If you're in the right part of Canada, may I suggest using a tank of ethanol-blend fuel every now and then? I use Mohawk Plus once in a while, especially if I've been parking in parkades, to help keep injectors clean, and to prevent gas line icing in winter.

Re: civic mileage
Hey,
thanks for the detailed reply... well, it seems like it did make a big difference, having the injector fluid in and all that... ( come to think of it, last time i changed the oil the guy at Walmart reassured me they cleaned the injector but it made no freaking difference, i probably got ripped off, heheh )... well, i live in Quebec so it's definitely not the right part of Canada ( just kidding ), but i travel to Toronto way too often these days, gotta maintain that damn civic..
