It was posed to me the other day that this product, 'Seafoam', will do about everything for my engine, but drive my scoot for me. Has anyone had any experience with this additive before and was it good or bad. Thanks for your thoughts.

it works awesome in your 2cycle weed whipper for cleaning out carbon build up . but in my CVO I am not so sure

[skippy]

I will put it in anything that has a motor on it    as a matter of fact i have been taking a swig about once a week seems to be helping

Its what I use in my bike for the long winters up in Northern Michigan...  Use it instead of other Fuel Stabilizers..

[foxman]

I use it in my SE Ultra, my wifes sportster, my dual sport bike, my kids dirt bike, my lawn mowers, just about anything with gas in it that you're storing for the winter. I run it in both Harleys year round. It is good stuff.

I have a friend that uses it in everything he owns, including his wife. Says he gets unbelievable results in his Mercury outboards. I have never used an additive......but when I do, it will be Seafoam!!

More marketing BS! These types of products are not necessary at all. Seafoam contains isopropyl alcohol (IPA), and does nothing that's verifiable to "treat" ethanol-containing fuel. They claim the product removes water from fuel... maybe it does by the IPA attracting the water in the fuel, but the Seafoam is still IN the fuel along with any water the IPA might have attracted!

Don't waste your money on these types of products. Modern gasolines contain all manner of detergents, etc. that help keep your fuel system clean.

Here's a useful link for more info... http://www.fuel-testers.com/is_gas_additive_safe_with_e10_list.html

One product I DO use is Sta-Bil Fuel Stabilizer - but only for off-season stabilization of the fuel in the topped-off tanks of the bikes and the boat. Topping off the tank before storage minimizes the air (which contains water vapor) in the tank. Less air = less water absorbed by the ethanol in the fuel.

One more point... Ethanol in fuel absorbs water. This is bad for the fuel system and for the whole engine.

Modern boats have water separator filters in the fuel system. My Volvo-Penta 5.7 GXi has a big filter in the fuel line, just before the fuel pump. It's about the size of an oil filter, costs $10, and lasts the entire season. These filters are there to separate any water from the fuel, and capture it before it even gets to the fuel pump.

You could fill the tank half full of Seafoam or any other fuel treatment, and it wouldn't "separate" 1% of the water that filter does. All the water would go right into the engine along with the fuel and the Seafoam. How does that help anything?

Had a friend that put it in his Goldwing, apparently too much off anything is not good, ate the rubber o rings out of his fuel pump. When he fired it up the sludge of rubber got in his carburetors and screwed up everything.  Needed a new fuel pump and carbs rebuilt. I helped him tear it down, never saw such a mess.

Snake oil. Don't waste your money on products not needed.

[Cat Eye]

I do not use it as an additive.
But after I discovered that my O2 sensors were reversed, I had major carbon build up in the front cylinder.  Spayed a little seafoam in the cyclinder let it soak for a few hours...then fired up it up.  Did that three time and cleaned/burned the carbon and cleaned up the cyclinder.

I think it has a purpose for interval cleaning....but would not use it on a regular basic.

Seafoam?  Isn't that for denture retention?

Works great in the diesel. Add a can around 500 miles before oil change. Half to fuel half to oil. Its cleaning something.
