fuel injector cleaners

[19accord92]

do these improve gas mileage at all? i figure a high mileage car with over 150k miles on it should give it a jug just for maintenance? what y'all think about that?

[pyro_maniac69]

its really never a bad idea to use them, they won't give you a HUGE milage improvement, but it is a nice little investment

[palinix]

You probably will see a decent improvement in gas mileage the first time you use it. I wouldn't use it too frequently though, maybe once or twice a year after that.

[bresk8r87]

yeah, i saw a noticeable difference in gas mileage the first time i used it, its not going to hurt to use it, just do it in moderation like everyone else said...

I agree 100%. Once a year is fine. Couple that with a new fuel filter(Fram makes decent filters) and you'll def. notice better MPG's.

Think how strong gasoline is...gasoline strips paint...fuel injector cleaner must be slightly stronger to fully clean out the fuel injectors along with gasoline...

Be careful, on a really old car, fuel injector cleaner once ripped through my friends 89 Camry and it caused his fuel injector O-rings to go...not a fun day for us...Gasoline vapors into the cars cabin...ooooohhh...tripped out all day driving home... "Roooooooo----aaaaaaaaaa---dddddssssss" lol...anyone see Tommy Boy?

Oh my....I think I like over did the fuel injector stuff a few times too many last year....maybe 4 or 5 times with sea foam. If you want to clean out the injectors then I would try shooting some carb and choke cleaner down into the throttle body and let it sit for a little while and then fire that baby up. It will smoke ALOT until most of the carbon is gone but its going to smoke less and less after every spray down. I noticed a LOT of carbon in my intake because the old man who had it never lit it up every once in a while. I would recommend using a can of sea foam in the tank and shooting a can of carb cleaner into the throttle body. I noticed a 5 mpg improvment doing this.

i wouldn't use it too often

the stuff is supposedly bad for the valves

[CB7 Architect]

once every year sound a good number, but clean the whole system, fuel filter and get a bottle of injector cleaners

[Spartan1987]

Use Lucas brand Fuel Injector Cleaner.
I just used a bottle of it and I definitely see some response as far as fuel economy goes, and/also a little power increase.
it's not even expensive either.

$.02 from a newb to the forum.

Yes, they work. They work very well, however, MPG increase should be a by-product of the real reason for running a fuel system cleaner and that is to clean the fuel system. Namely injectors and valves. Use a good, concentrated additive such as Gumout Regain or Chevron Techron. If you haven't done this in awhile, do back to back fill-up treatments. You should notice smoother idle and throttle response. Proceed every 3-4k miles or so. Overduing is using it every fill-up. Otherwise, don't worry, they won't harm your car.

Seafoam through the pcv or brake booster line works great too for burning crude from your intake.

Stay away from any fram filters, especially the oil filters. They are proven to be possibly the worst filter available. Go WIX or OEM for a fuel filter.

I am a firm believer in chemical cleaning additives(used correctly) and synthetic fluids. Like most everything, you get what you pay for.

Maybe so, but their oil additive isn't:
