    Anyone using it in their HT engine?

    I bought a couple bottles for use in my car (I drive 150-200 miles a day for work and every bit of mileage gain is worth it). Reading the bottle, it says to use 1 oz per 1 gallon for use in small 2 stroke engines so figured I'd give it a go in my motored bike as well. I'm running about 25:1 oil/gas mix and added the 1 oz of Seafoam to that.

    I added some and noticed that the bike is running quite a bit smoother now and is a bit quieter as well.

    Anyone else tried this? If I don't have to tear the engine down as often to clean carbon deposits, that's gotta be a good thing.

    I swear by it. I used it im my rx-7 with a wankel rotary engine in it and every other car i've owned or worked on and it does wonders. The wankel has a oil injection system to lubricate the seals and it cleared them up and resulted in a noticeable increase in power. I would only use it as maintenance on the motorbikes though as it does rid of carbon. Put in a 50-50 mix of seafoam and gas with about 1/8 gallon, but dont use it on every tank or it will hinder the lubrication of the engine. Be advised that it will cause a good amount of smoke from the exhaust, but that is normal.

    I've used Sea Foam before for helping clean carbon deposits, and it seemed to be very effective. I would be a little hesitant to use it in the fuel for a two stroke engine because it contains powerful solvents, and while the solvents are effective at cleaning gum and carbon deposits, they will be a detriment to lubrication and engine life when used constantly. This is just my opinion, YMMV. :)

    I use it in my outboard for my fishing boat and in my MB. I've heard good things and believe in it, but I think the last poster had a good point about the solvents (I may only use it every 3rd tank or so now).

    Sounds a bit like redex over ere in England.

    This is what they claim.

    Assures fast starts
    Smooths rough idle
    Restores power
    Cleans fuel injectors
    Cleans carburetor jets
    Cleans carbon
    Stabilizes fuels
    Upper cylinder lube
    Removes moisture in fuel
    De-icer
    Frees sticky lifters
    Frees sticky rings
    Removes moisture in oil
    Cleans P.C.V. systems
    Cleans catalytic converter odors
    Oxygen sensor safe

    I love this stuff but I wouldn't run it full dose 24/7 for reasons arceeguy stated.
    I use it in small doses year round in everything. (preventative maintenence for poor fuel quality) My fuel always has a trace in it. About twice a year I'll give it a full dose.

    woo -- more questions and talk regarding Sea Foam
    much has been said around here about ((the Sea Foam Thing Stuff))
    search engine should bring up plenty
    never have tried it
    but -- all of this talk makes me want to buy some !!!!
    next time Iam at the auto parts store -- I will grab some -- what the heck !!!!

    main thing -- ride the motor bike thing

    Great for occasional use in 4 stroke engines. A waste of money in 2 stroke HT engines.

    I wouldn't risk using it in a Wankel engine unless I knew it was safe for the side seals and the solvent would reduce the efficacy of the injected oil for the apex seal lubrication.

    the day came -- tried Sea Foam

    yes -- the little Robin was having a slight lose of power
    cleaned everyTHING except the screen in carb -- was told there was one in there
    the Sea Foam did make a difference
    running much better
    will be also trying some in my Jeep etc

    How much and how'd you apply it MM? Get a lot of smoke?

    I've noticed these Robins do tend to carbon, pull the plug and shine a light and you see the piston crown coated. I think it's the crankcase return for the CARBII cert.

    well Happy Valley
    it wasn't very scientific -- not what I would recommend to others
    just poured in a little fair shot -- one shot in each of two tank fulls !!!
    always wonder about these type cleaners THINGS -- not wishing to get THINGS TOO HOT
    it only smoked a very little
    like I said it did improve the slight slugglish feeling -- back to orig -- not real sure yet ??
    but as you have mentioned
    I should at least peek down the old spark plug hole
    also off the subject -- with the around 2,000 miles -- may be time for a valve adjustment ??
    Happy Riding from MM

    Oh, ok didn't know it could be used as a fuel additive. I'm used to the guys on another car forum talking about pouring it right down the gullet of the running engine....and really smoking up the neighborhood lol. Thought maybe misting some out of a little spray bottle into the carb might do the trick on these little one lungers.

    Yes to valve lash check. You've got the pdf service manual from R/S right?
    Good tutorial there on checking valve clearance.

    Well i use a similar product called redex, and i simply tip a trickle into the intake with the airbox off. Rev the engine up to stop it from dying out. give it some revs to get it out of the system. cleans it out pretty well.

    Dont forget only a trickle, or the engine will get flooded with it.
