| fuel injector cleaners
So, I'm aware that this topic has been beaten to death.. But it seems like there are always yay and nay sayers.
A friend of mine was getting poor mileage on his Civic. Only ~300km per full tank.
He changed filters, plugs, pcv, etc, but no help.
He finally tried some STP cleaner in his tank, and he ended up getting an extra ~100km per tank!!
I never believed in these fuel tank additives, but I'm tempted to try this out. Wondering if anyone has used these and got results?

The ~100km is probably exaggerated. But he seems really chipper and excited about it. Must've done something right

Changes that big are usually psychological.
You try a new additive, and you're consciously looking for a change so your driving behaviour changes. That makes more of a difference than anything.
I use seafoam twice a year in my fuel, but I never really notice much of a difference. It's more of a why-the-hell-not sort of thing.

I used fuel injector cleaner in my car about a month ago, and as far as I know, my driving style hasn't changed. Noticeably, I saw about a 25% increase in my mileage; I could squeeze almost an extra 100km out of my tank than before I poured in the cleaner. It might not be much, but it's something  | |

But that's exactly why I'm tempted to try the STP stuff. For $5-$10, it really is more of a why-the-hell-not.

Gab, try outboard 2 stroke oil.
For cars, I've used this with good results (click pic):

I use it if I have a choice. Otherwise, I chuck whatever is free at work, in there.

I would stay away from seafoam, you either do it right and it works wonders or you fucked up your car and it runs like shit.

Posted via RS Mobile | Well, the weather is now getting slightly warmer. That may play a role into his results.

If you put it in your intake and you do it wrong, you can have a problem. But you have to be pretty dumb to screw it up...

Just cause you didn't have any issues with seafoam doesn't mean problems don't exist.
There are issues with seafoam search around the internet.
It works great, I'm not denying that fact. But the cost of just cleaning out your car isn't worth the hassle of replacing parts that went wrong.

Just cause you didn't have any issues with seafoam doesn't mean problems don't exist. | If your car is having problems, changing your fuel filter should be on the list of stuff to do anyway, lol. The only problems I've ever heard about seafoam are people incorrectly doing the intake treatment and conjecture about using it as an oil flush (I'm against the idea of oil flushes in general)
If you have enough crap built up in your system that an fuel treatment is going to make things worse, you were heading for disaster anyway. It was just a matter of time. This is the same mentality that gave us the myth that transmission flushes cause transmissions to fail.

I'm sure the difference is probably miniscule... as this whole process is anyway.

Ohhh... the vac brake line... Yea... you could use that, but it's not a very good idea for a couple reasons. One is it's really big, so you can suck up a LOT of fluid really fast, causing hydraulic lock and broken parts. Two is it usually only feeds one cylinder. You should really use a vacuum line on the throttle plate, most cars have one for the evap system. Something tiny, 3/32 inches or so. That way there's practically zero risk of hydrolock.
I've never had to change a fuel filter after seafoaming a car, but I'm just saying if that did happen... change it. It's not a big deal to buy a $15 filter and change it!

Waste of money. The only fuel injection cleaning that can give results is something like a Motorvac. For those who don't know what that is, it's a fuel injection flush machine. You dis-connect your engine from your fuel tank and connect it to the flush machine. Your engine runs on the fuel/cleaner mixture in the machine instead of gas in your tank. The machine has its own fuel pump/filter and it "replaces" your vehicles gas tank/fuel pump.
So instead of diluting your bottle of cleaner in a tank of gas, you're running a concentrated mixture from the flush machine. The cleaner used in a Motorvac is very strong and I've seen it eat/melt components if left for too long. It's not something that you should put in your gas tank for this reason. This is why it actually cleans injectors - because it's strong. When your flush is finished you connect your engine back to your gas tank and the "fresh" gas gets rid of the last traces of the cleaner so you don't have to worry about it contaminating your tank and damaging something later on.
That said, even this type of machine would never give anyone a 25% increase in mileage. I have seen noticeable and measurable improvements, but they are still minor.
The main reason I don't buy these 10% or 25% claims is because of how your fuelinjection system works (specifically the ECU). If your injectors are so badly plugged that your mileage goes down by that much then you're going to get a Check Engine Light with faults for things like fuel trim or misfires. If your engine runs ok, and there's no CEL on, then your injectors are ok. Maybe not perfect, but within spec. And since your ECU automatically adjusts itself over time to compensate for injectors, fuel pressure or other things that change, then "cleaning" them isn't going to make much if a difference.

Posted via RS Mobile | Yeah, I'd be happy if any of this gave me even a ~10% increase. For $5 a bottle, why not?
But my friend who got the crazy increase won't shut up about it, so I'm assuming he's not lying. (What reason would he have to lie, anyway..)
My guess is it's because he's been so worked up about the bad mileage that he started replacing EVERYTHING. So maybe it's a combination of all the new parts and the warmer weather, and the injector cleaner was just that extra little kick to boost everything up to noticeable results.
