Does fuel injector cleaner really work?
EDIT: I guess i can't edit the poll. If you think i should just use seafoam instead of "injector cleaner" just post.

As for whether or not it will fix your specific issue, that's impossibile to say, since several things can cause a lean condition. But it can't hurt to try.
Using something like Seafoam at every oil change wouldn't yield much of a difference on your vehicle. However, using it on a used car you just bought with XXX,XXX miles, you will notice quite a bit. Seafoam will dry out seals is used often enough.
These "cleaners" are hit and miss. You occasionally will see something that says "Restores lost compression" or "Repairs blown rings"... It's all advertising propaganda. Specifically that stuff you see in cans called Engine Restorer or something like that. There is NO miracle product.

It would start running like crap in x,xxx miles. I'd put in some STP concentrated FI cleaner in the black bottle with a full tank of gas, it would feel like the truck had a full tune up by 1/2 tank.
I've never been able to duplicate the results with the same product in any other vehicle.
Thats my experience.
line rust, no. This latter I have had bother two vehicles, it accumulates
at the end-of-rail positions.
Now there's actual-lean, and there's indicated-lean. So be sure what
you're chasing.
doesnt todays fuel have cleaning additives already?
Some of them do but not all.
I'm just forewarning users that some of the stuff they may pick up off the shelves won't do as it claims while others will.
For example, you have two cleaners. One is in a plain white bottle, costs 2.99, and simply says "Helps to fix rough idle, misfiring, and poor fuel economy." The second product is in a purple and black bottle with fancy lettering and costs 7.99. They claim the same as the number one product however makes some outlandish claim about it being just as good as new injectors or something.
You'll most likely go for the number 2 product. Will it do what it claims? Probably, without the last part being absolutely correct.
So, when in doubt, check out the MSDS. They could be the exact same product, or it could contain a possibly dangerous component that'll screw something up.

So obviously I believe in engine cleaner but not so much in fuel injector cleaners. Till last week. Frustrated by misfiring of a 2002 Jetta (not at start but only when it's at operating temperature and running lean) I was at the gas station and just took a random bottle of fuel line cleaner and poured it in with the gas. Few kilometers later and misfiring never happened again. Still over 1/2 tank full I am now wondering what helped the most.
1. Full tank makes for better fuel line pressure because the pump or the filter have performance issues.
2. Possible water accumulation in the tank caused by low fuel level for long time and car not driven very much just sitting in the sun and because it's black it heats up during the day and cooling during the night sucking humid air repeatedly. New fuel with ethanol dissolved the water and solved the problem.
3. Fuel cleaner cleaned injectors.
Somebody earlier mentioned potential problem that using the fuel cleaner will cause one not realize what the real problem is.
So I have my doubts and would like to here if someone experienced same.
I know it's an old thread.
