I know this may seem like an easy question to answer, but what Fuel Injector Cleaner do you all suggest?

I've heard that STP, Pennzoil, and Synergyn (sp?) are good brands.

I like Marvel Mystery Oil's Fuel Injector Cleaner.

I recall, even from my teenage days, these guys' additive clearing up problems with bad gas. Not a very scientific opinion, just my experience and perception.

I'm not quite sure if this is a joke name or not, because I've seen less believable ones, but where would I finh this stuff.

Chevron, Redline, Amsoil PI, BG44K, are pretty good.

at the dealership i used to work at, gm techline told us to mix 1.o ounce of gm top engine cleaner with about a pint of gas in our OTC fuel injector cleaning kit..(involves diabling the fuel pump and running the car with shop air pressure regulated into a contaner of this mix and supplying this mix into the fuel rail and running the car.. i hate to say it, but the ford motor company fuel injector cleaner works best. it is a pressurized can of the cleaner that is plugged into the schrader valve on the fuel rail. and tests prove this one is the best.

I used the F*RD also when I worked in a shop and that stuff has to work good-hell it ate the copper discharge tube off of a bug sprayer. We used it liek the GM counterpart, disabled the pump, tapped into the line and pump the pressure up. For got to clean it out once and the discharge tube was corroded off. Good stuff!

I like the cleaners which double as upper cylinder lubes too, so I prefer Schaeffer's Neutra product, Amsoil's PI, or Lucas UCL. I also prefer to add in small regular doses with every tankful. I use Neutra at a ratio of one ounce every five gallons.
