    Seafoam works awesome in your fuel. It cleans out your entire fuel system. But when it comes to your oil, the only additive i'd ever put in my oil is Lucas Oil Stabilizer. It cant be beat.

    Use it in EVERYTHING! In some of my older snowmobiles it has even dulled down or removed the pinging sound from the engine!
    SEAFOAM, I PUT THAT @#!$ IN EVERYTHING!

    Wow, I've never even thought about using seafoam. Is it only for older trucks?

    Definitely not. Carbureted or Fuel Injected. Use it. I swear by it. If you are skeptical, use a small amount at first, then WHEN you notice a difference, put in the recommended amount.

    Lawnmowers, quads, snowmobiles, cars, trucks, motorcycles, snowblowers

    I've used it in all and have nothing but praise.

    It's not to be used EVERY time you fill a tank of gas... I generally use it in the last two tanks of my snowmobile before storing it for summer, and the last two tanks of my boats before storing them for winter.

    I also put a can in mid way through the season and possibly once again IF I am running the machines alot.

    Put it in your truck every 3, 4, 6 or 12 months... it's up to you and also depends on how old the engine is. (Older usually using it more often)

    seafoams good stuff but probably not the entire fix for your ruff idle

    open the butterfly valve on your throttlebody and see how much carbon ya got in there. A quick trick but not a complete fix is to hold that valve open and spray a can of choke clean inside. wipe out all you can, when you go to crank the truck hold the pedal at WOT so you dont get a backfire. again not as good as a regular carbon clean service but it will help alot. May not be to noticble but if you monitor your fuel trim before and after you do it you'll see

    I think I'll give this a try today. I used BG fuel injector cleaner, stuff that gets sucked straight into the fuel rail after you disable the fuel pump.. after that I cleaned the TB and that all seemed to make an enormous difference.. but I still have a slight stumble at idle like an injector is stumbling. Its like $7-8 a can, so its worth a try to get the rest of the carbon out of the parts that the fuel system never touches.

    But at the same time I've heard you're supposed to do the plugs after you suck Seafoam through the vacuum line...?
