The stuff you get in the bottle at the local chain store probably won't do too much actual help. A real cleaning (which requires you to remove the injectors and have them serviced in a machine) will most certainly help. I hear there is a compressed-fuel bottle that you can piggyback into your system that works almost as well as the complete cleaning, but I don't remember how much it cost or where to get it.

If your injectors are really funky, it may not help, but worth the couple of bucks to try it out. I put a jug in both my vehicles every oil change. It's not that expensive. I've not had any injector problems yet, so who knows?

i have an 88 300 as well and i noticed my truck was getting really crappy miles, like 7.5-8 mpg mostly city and it was starting to hesitate. one of my friends showed me this place in unionville,CT called the driving image, they had this pinkish stuff called complete fuel system cleaner and it cost about 6 bucks to treat 20 gallons, the tank before i got 110 the next tank after i put it in i got over 180 miles on 18 gallons. this last time i probally could have gotten 160 or so(driving alittle harder) but i dont like to go below 1/4 of a tank.

I could be crazy but I recently put a bottle of Sea Foam (I think that's what it was called) brand fuel injector cleaner in a 2.9 ranger I bought about a half a year ago and it made a believer out of me. I was consistently getting 19 mpg, the last 5 or 6 tank fulls I've got 22 mpg and it took the hesitation away too. Maybe I just got lucky, who knows.

oh ya it was, im glad the only money i have to put up is lunch and insurance. i forget how big it was, i threw the bottle in my toolbox and it has disappeared into the abiss. i think it was about 5 or 6 inches tall and a couple inches round, your average size bottle, some of it IS due to my foot being alittle on the heavy side. so far on this new tank ive gone 45 miles(mostly city) and the neddle is just startin to move.

I use Red Line fuel system cleaner. I have used it for a couple of years on all of my vehicles. I had to have the intake gasket replaced on my Suburban(I know, no comments please). When the manifold was taken off there was carbon build up on the very front where less gas flows but the rest of the manifold was clean. The mechanic was skeptical when I told him before removal that I used Red Line but when he saw what it did he told me to keep using it because it works. This was at 70k miles. I looked a the manifold when it was off and was impressed. I use it about every 6 months and it seem to smooth out the engine. Got started on Red Line when I owned a diesel. I get Red Line at PEP Boys, I have not noticed it at other stores, about $7 a bottle. My 2 cents.
