$15 STP Fuel Injector Cleaner - Worth it?

[AZoutdoorsman]

is it worth it to to buy the 15 dollar STP fuel injector cleaner???

$15?! You can get the black bottle of STP fuel injector cleaner for $2 at a parts store or any auto section of a department store...maybe slightly more at a gas station. The silver bottle of STP "fuel system cleaner" costs more but still..not $15. Even Seafoam is just $8-10 a can.

If you really need it, I suggest the $2 black bottle of STP Fuel Injector cleaner. It can also make a HUGE difference if you use gasoline with better detergents and additives like Chevron and Shell. I would definitely NOT pay $15, since you're better off spending the money on better gasoline or finding a place that carries the black bottle for $2-3.

What injector cleaners are safe for our O2 sensor? I cooked one in my old car with some injector cleaner one time and never used any since and don't want the same problem with the X.
My idle isn't too bad, and no hesitation when on the gas. I know the plugs are old. Any need to even bother with the stuff and risk frying an O2 sensor?

Any good brand-name (STP, Gunk, etc) and most store brand fuel injector cleaners are sensor safe, and usually state so on the bottle. If you overuse it by putting in WAY too much or putting cleaner in tank after tank, it will be too concentrated and foul up your plugs, and possibly sensors as well. I personally just use the STP fuel injector cleaner in the black bottle for my X if it feels like theres an injector issue.

Best bet is use good gas to prevent it from happening and clean the injectors tank by tank, and just use the injector cleaner sparingly.

chevron's techron fuel injector cleaner is a winner in a lot of tests of over the counter cleaners.

or try seafoam thru the tank.

stp cleaners are a waste imho.

I think the bad thing with some of these "magic cleaners" is that as far as I am aware there is no comprehensive comparison on the aspects of each ones ability to clean your injectors. This has been debated, and will continue for generations. The bottom line is, be careful what you run through your engine or you may cause more harm than good. I think an occasional can of injector cleaner is great, maybe a few times a year. Change fuel filters often to keep dirt out of your fuel rails. If you are really concerned with your injectors have them ultrasonically cleaned by a professional. By all means don't fall into the marketing hype on the side of the bottle, however regular care and maintenance will go a long way. As everyone has already said, you don't need to spend $15 on a bottle of injector cleaner.

Just my opinion, others may vary
