fuel additives

i walk into wal-mart/autozone/ etc, and i see a bunch of fuel additives. Octane booster, fuel injector cleaner, gas mileage improver, full fuel system cleaner, etc. has anyone heard of any test done to see if these even work. I put the fuel injector cleaner in about every 2000 miles, and i try to put the octane booster in every now and then. I cant really notice anything significant, then again, they are just suppose to clean. But does anyone have proof that any of those products actually work? wasting money maybe? thanks

Most are a waste of money. I still dump in a bottle of fuel system cleaner every 5k miles or so, it's only a few bucks and if it does ANYTHING I'm happy. Hard to tell if they actually work though, and I have never seen any proof.

I use redline fuel system cleaner in my 300zx and it feels a little more snappy.

some work others dont, rule of thumb is if it sounds to good to be true usually it is

Best thing to use Sea Foam... 4.95 a can..ask any guy who no's anything about a car and they will tell you..

What is it and where do you buy it? I've never heard of it...

The only additives I've ever used that I actually believe to do somewhat what they were supposed to are injector cleaners. Sea Foam works great and so do some other good brands. Sea Foam comes in a metal brake-fluid type container and I believe the colors are orange and white. Other than that, those fuel additives like octane booster and mileage booster, I wouldn't use them if someone paid me to, those remind me of late-night infomercials, shit that people think of just to rip other people off because it "sounds" convincing.

yes sea foam does work great and i have used it muptiple times. BUT, that is not a fuel additive. that has to go through a vacuum line, throttle ody, etc. i was asking about just the one-bottle-pour-it-in-your-tank-when-you-fill-up additives. the only ones ive really used was the fuel injector cleaner, and sometimes the octane booster thats "barley street legal" :rofl: but i didnt notice anything, so i stopped using it. any logs/proof of this stuff? Thanks

Whats funny is how they put in big bold letters on the bottle "MADE WITH JET FUEL". hahahaha riiigggghhhhttt. That .01% of jet fuel they actually add makes all the difference, especially for honduhs.

Id use some fuel injector cleaner, but thats about it. Put too much of that shit in your tank and you wont be burning much gas ;).

Its a great product there is a thread about 100 pages long about it on dsmtunners...but the site is down right now...so i cant get you the link..

I did a little study on this shit. Octane booster when mixed with 35 liters of 91 gas raises the level 7 points.... Sounds great right don't be fooled.. it takes 10 points for 1 octane level. So after the entire bottle instead of running 91 your running basically 91.7... ABSOLUTELY useless a waste of money. Just drive race gas or a mix if you want don't bother with the bottles.

Why would you notice anything by upping the octane??? Are you having pre-ignition problems? More octane doesn't equal more horsepower. Higher octane levels mean higher resistance to pre-ignition, so with more octane you can run higher compression and more timing, this is what gets you more power. It is pointless and foolish to waste money on octane boosters expecting to get more horsepower. But I'm sure the octane booster people appreciate your $$$$$money$$$$$ :icon16:

The only thing I do use every once in awhile is the fuel injector/fuel system cleaner. I am almost positive that these products do work to some extent. My brother has a 92 camero with about 200k miles on it. It started having fuel problems and it kept stalling(its an auto) So I told him to buy a bottle of the fuel system cleaner and put it in(only 5 bucks can't hurt anything) It deffinatly helped because, after he added it to a full tank and ran it for awhile it now runs great and shows none of the previous fuel problems.
