    Cheddar little powerpoint presentation on that site. Seafoam has been proven to me more than once... I shaved 6-8 seconds on my holeshot after decarbing my 200efi with Seafoam. And i have seend improvements in maybe cars/trucks after doing the same thing. I'm a seafoamer for life

    wal-mart and the autopart stores around here get $9.99 for a can for seafoam yet both farm & fleets that are within driving distance from me have it for $6.50 everyday. a decade ago when all I had was a 1985 OMC 90 horse I use to mix my own oil (plugged the VRO system) and add OMC 2+4 fuel conditioner along with carbon guard. This got expensive quick over the course of a season. The mechanic I used to use said to me "why don't you just use seafoam instead, we use it on all our own equipment". I've been using it ever since.

    Just go to a fleet or farm type store and you can buy Seafoam for about $6 a pint everyday when you buy it by the gallon.

    A quick look at websites reveals that they both pretty much claim to do the same thing.

    For Engines in Storage

    STP® Multipurpose Motor Treatment does not contain water absorbing alcohol like other fuel stabilizers and helps prevent many of the negative side effects that can happen when engines sit idle for long periods of time. It helps:

    • Stabilize fuel
    • Fight rust build up in fuel tank
    • Prevent oxidative degradation in fuel
    • Fight tough cold starts
    • Prevent corrosion in the fuel line

    For Engines in Use

    Great for the fuel system, crankcase and intake, STP® Multipurpose Motor Treatment helps:

    • Clean engine deposits and fight friction
    • Clean fuel injectors and intake valves
    • Protect against viscosity build up
    • Protect against crankcase sludge
    • Prevent fuel line freeze by removing water
    • Provide upper cylinder lubrication

    Use regularly to protect and maintain all of your gas and diesel engines.

    Sea Foam Motor Treatment is a highly effective and completely safe additive that can improve the performance of your engine as it helps too:

    • Clean entire fuel system, including carburetor jet or fuel injectors
    • Clean deposits from the combustion chambers and pistons
    • Stabilize fuels for up to 2 years
    • Lubricate the upper cylinders
    • Control moisture in fuel
    • De-ice frozen fuel lines
    • Quiet noisy lifters

    All fuels leave varnish deposits, which over time build up, collecting deposits from exhaust and impairing the efficiency and effectiveness of your fuel system and combustion chamber components (pistons, valves, spark plugs.) Sea Foam Motor Treatment was originally designed to remove this varnish build-up, and nothing does it better or safer than Sea Foam.
    Sea Foam Motor Treatment can also be added to your oil to re-liquify oil varnish deposits and quiet noisy valve train components, enhancing the effectiveness of the lubrication system and adding to the longevity of critical engine components.

    Good oil will still leave carbon deposits in a two stroke. Need to run a decarbon agent of some kind even with the best oil.

    I'm sold on Seafoam. I add a can (16oz) every fillup of my 1998 Glastron GS185 Ski & Fish, Volvo Penta 135. Seafoam improved starting, smoothed out rough spot in acceleration around 2600 rpm's when cold, smooth idle, etc. I'd love to find it for $6.50, so I'll be checking Tractor Supply. However, no matter the price, I'm a Seafoam believer!!

    I love it too...I use Seafoam in everything...Here's my proof it works....I had an Echo weedeater that was a B$tch to start, took at least 8 pulls to get it to just hit...Used seafoam in it for at least 3 tanks, NOW IT STARTS ON 2 PULLS OR LESS, every single time I use it. Idle is way smoother than before. SO the both boats, Both Toro lawnmowers, blowers, weedeaters, and the Chevy get some running through it. I use it so much I can prolly skip a month of use and they wouldn't even know it...Stick with the Seafoam..Gal. is cheaper.

    STP® oil and fuel additives have been specifically formulated for use in four-cycle gasoline engines. Extensive testing in these engines has covered a broad range of passenger car usage and has clearly demonstrated the value of our products in these applications. However, we have not evaluated the performance of our products in two-cycle engines. Therefore, we do not currently recommend that they be used for two-cycle applications.

    This is from he STP site....I think that says it all

    When I bought my boat used it had a crappy idle and stalled at times. After reading some articles online I determined that I probably had excess carbon build-up either on my piston rings or exhaust ports or both. I performed a decarbon treatment with Seafoam, then took it out for a hard run and it was cured. That sold me on Seafoam. I now add some with every tankful. The proof is in the pudding!!

    Oh yeah..Check inside the prop of a guy who DOES NOT use Seafoam and A GUY WHO DOES use Seafoam...There is your proof...Matter fact go outside now and check inside your prop. If its black smudge, black chalky looking film then you need to use that seafoam NOW...
