just wondering how often to use the stuff, how much it helps, and which brand works best. i was also wondering about the engine restorers and if they worked any. guess i just watch too many infomercials.

Well...
if it's anything like the fuel system cleaner stuff don't use it. that f1 stuff clogs your fuel rail and filter, as far as I've seen. i'm not sure what other people's experiences have been on this and i haven't used it myself but i saw on this one site where a guy used it and it clogged his fuel filter and started to clog his rail.

I've used STP before, couldn't tell the difference...

Different people are going to swear by different products. You're not going to get a majority on any answer :wink:

once i put this new engine in the injectors wouldent fire. i poured some X1-R into them and after that the rngine fired right up. i think its good stuff but im not sure how great of an affect anyones looking for. Think of how long it took to build up that crap in your fuel system it would take just as long and be just an gradual to get it out.

I put in a bottle of regular cheap $1/bottle fuel injector cleaner every time I change the oil. Basically it's preventative maintanence and it doesn't give me any problems. Just don't fill up your gas tank while the fuel truck is unloading or right after and I doubt you'll ever need to clean the injectors.

It probably clogged things up because it was doing its job; removing rust and scale deposits in the tank most likely. Thats the problem, it loosens that crap up and it has no place to go but through the filter, rail and injectors clogging things up. Some of the more potent chemicals will actually dissolve some of that junk and do some good, but for the most part they are just for maintenance; that is, to keep that stuff from forming in the first place. So, if your fuel system has a lot of corrosion already, expect to be changing the filter quite a bit in the very least.

Gasoline is not a stable substance. If allowed to sit it will separate into a black sludge and a thin, kerosene-like, fluid. The black sludge is the problem. Things like peices of rust that are too large to fit through the fuel system won't make it past the screen on the pump's in-tank pick-up, and if something does happen to make it through, the fuel filter will grab it. (we have plastic tanks on the escorts, btw, very little rust) If you drive your vehicle regularly and go through a lot of fuel, then injector cleaner won't have any sludge to attack. If you frequently leave your car parked for weeks at a time you may want to consider running fuel stablizers.

If you want to clean your fuel injectors, remove them and have them sonically cleaned.. it'll be cheaper and easier than buying and pouring in 100quarts of injector cleaner. Remember, most big brand name oil companies already have adequate detergents in their fuels.

Yeah I always buy at least 89 octane from reputable stations... like sunoco, etc. Actually I've got a half tank of 94 in my GT right now! woot

Higher Octane isn't going to clean you fuel system any better. But the point about haveing detergants already in the gas is true. As far as available cleaners off the shelf, Techron is the best I used. I also had many of my teachers at my automotive school swear by it.

There must be stuff that deposits in the lines. Ive replaced a fuel filter in the car and it was full of crap. Some kind of sediment or scale. Either that or its the filter thats corroding. Who knows.
