    One of my friends today introduced me to Seafoam today and everything he said about it was amazing and how it cleans the internal fuel components. Of course, I've seen the bottles at my auto shops but never bothered to look at them or read them at all.

    I was wondering if you guys used Seafoam before (or something like it) and could you tell me if it was worth the treatment or just another gimmick?

    Plenty of thread about this around if you search. I wouldn't introduce it into intake again since it just pushes everything down into the cylinders.

    Okay, I was planning on using it in my gas tank and I didn't know if it would affect something. Plus, I've heard mixed reviews about it, even with me searching around. So I'm not sure what to believe.

    It works fine in the gas tank if you follow the directions.

    Red hot glass pack muffler dumped preaxle raptor liner bed and top rails and fenderflares and rocker panels. Hunter side steps. Plasti-dipped upper fenders and emblems. satin black spray paint here and there inside and out. 5100's set to 1.75" up front and modified zuk mod coil spring lift for about 2" in rear paired with 5100 also. C channel front bumper. Maxxis bighorn 255/85/16
    i do a 3rd in the tank 1/3 in the brake boost line and 1/3 in the oil about 1 week or so before i change my oil. i do get get a lot of white smoke after i start it back up after the brake boost inhale, which is "cabon build up" getting blown out. i do feel that it helps clean the crank case from deposit and gunk that builds up between changes and what not and helps keep it as clean as possible. i doubt it really does much more than the "injector cleaners" when its in the gas tank, but i have nothing else to do with that 3rd so might as well.

    Good question to ask.

    In short, the reading I've done lends to the notion that if you buy fuel from one of the major gas providers, the additives that they have in their fuel blends are enough to keep your engine running clean. However, not everyone buys from the big guys. So, lower grade fuels can cause buildup in the engine. When used sparingly, Seafoam (or the like) can remove deposits. The concern is what this or other additives do to your engine other than removing the 'harmful' deposits. Some suggest that prolonged use will damage the engine's soft petroleum based components. Basically, a bottle of the cleaner might not be mixed proportionately as prescribed and do some harm.

    Here's a link to a related item - www.skepdic.com/comments/slickcom.html

    I believe if you do a search on the web, you'll find other articles of a similar kind. Most suggest additives are 'snake oil' and not worth the investment. If that's what you conclude (as I did), try running the 'big guy's' fuel blends for a few tankfulls and see if your MPGs/Performance returns to norms. If not, a professional cleaning, while more expensive, might be a good alternative. Good luck!!

    Gas additives do nothing for the intake. The EGR and PCV systems introduce contaminents into the intake. They condense and solidify. Seafoam helps to soften and remove those deposits.

    I just did this process through the vacuum line. I can NOT vouch for any HP or performance gains. What I CAN tell you is that my truck idles and accelerates much much smoother. 150,000 miles on the odometer. I don't think I gained any better fuel economy even with the addition of the deckplate mod. Also I have the 2.7l 4 cylinder.


    After further review the call on the field is overturned. I gained about 2mpg's.

    I heard this gunks up your oil and to do it right before you get an oil change not after.

    Run Chevron 90 octane. Take it on the highway and stomp on the gas a few times for about 10 seconds a piece. Does pretty much the same thing. You can also use TB cleaner and clean the TB. Once again, start it up, foot to the floor and take it on the highway again.
