How many of y'all use Sea-Foam addative in your vehicles, ATV's and outboard motors? I've used it some in my outboard tank but can't tell if this product is for real or some kind of neat packaged snake oil. I know serveral people who swear by it, but at $8 per can what makes it better than all other addatives. What are y'alls thoughts on this product.

Always...because friends that know a whole lot more about motors than I do (which is admittedly not much) give it the highest recommendation.

I use Sea Foam on a regular basis, keeps my injectors clean & after you try this a few times you will tell the difference also. I use it my lawn mower & my utv also.

I don't know anything about it, but it sounds like it could be illegal ---possibly an EPA or DEQ violation. Someone call the game warden and the sheriff. Citizens arrest, citizens arrest,.... Where's my bullet?

What's in it...how do it work? I know of some folks that add some rubbing alcohol to the fuel as an addative. I will never pay $8 a bottle for rubbing alcohol.

i use it in everything. it is a petroleum product (why it is so high now) that keeps the gunk out of engines - great for keeping carbs from accumilating build-up in the jets of small 2&4 stroke engines (directions on the back for a good cleaning as well as how much to put in gas jug for everyday use). i also use a can every other fill up since i got a quarter tank of water instead of gas in my yukon, to keep fuel system cleaned out and flowing good.

* i haven't ever used it in the oil of the engine, only gas.

Why they say it works:
Sea Foam is a safe and versatile additive that can be used in fuel, oil or added directly into the combustion chamber on 2-cycle, 4-cycle, rotary and diesel engines. Sea Foam is a 100% pure petroleum product, so it is as safe for seals, o-rings, sensors and other fuel system and engine components as the fuel or motor oil that runs the engine. Sea Foam contains NO harsh chemicals. All three types of engines (2 & 4 cycle, rotary and diesel engines) suffer from the problems described below, all of which are addressed by Sea Foam.

Old petroleum residue (gum and varnish) buildup. All fuels and engine oils leave behind residue deposits that accumulate over time. In the crank case, this residue builds up around lifters and rings, preventing them from functioning properly. In the fuel system, residue builds up in the injectors or carburetor jets, on the tops of pistons and on the backs of intake valves. Carbon in the exhaust adheres to this residue and forms carbon deposits. THERE IS NO DIFFERENCE BETWEEN THE RESIDUE IN YOUR CRANK CASE AND THE RESIDUE IN YOUR FUEL SYSTEM. IT IS ALL PETROLEUM VARNISH. Sea Foam slowly and safely re-liquefies this varnish so contaminants and carbon deposits can be safely cleaned out of the systems as the engine is operated.
Lack of lubrication. This can occur in the fuel system as the result of dry fuel additives such as ethanol that actually remove lubrication from the engine components. In the crank case, varnish buildup around the lifters and rings can prevent the oil from properly circulating and lubricating. Sea Foam contains a high-temperature penetrating, lubricating and cleaning oil that will not evaporate even in high heat areas like the combustion chamber. It is also able to safely dissolve varnish from lifters and rings so the oil can flow and lubricate properly.
Moisture. Fuel can absorb moisture from the atmosphere - even more so with the addition of ethanol. Crank case oil can also become easily contaminated with moisture. Sea Foam fully encapsulates the water molecules in the fuel and oil to prevent phase separation - rendering the absorbed moisture harmless.
By addressing these three key factors that produce premature engine wear and cause many common drivability problems, Sea Foam can be used by professionals and do-it-yourselfers alike to safely eliminate many contamination and lubrication related performance problems and help prolong the life of an engine. A clean, dry and well lubricated engine will run smoother and more efficiently.

Does it work on duck weed?

DM I have sold and used it for 15 years. I run it in my truck, boat, atv, lawn mower, chains saws and weedeaters. I have not had an ethanol issue. Seafoam was Johnson outboards additive on old seahorse motors that you mixed 30 wt oil in the gas and it kept the carb from gumming up.

I have an 08' honda that the ethanol started making it miss(6 or 8 tanks in) I started using the sea foam and in just two tanks it runs like a new bike. Seems the Fuel Injection, doesnt like the ethanol

it does, but quite expensive at $8.xx per can (16oz i think). be easier to just pay $3 for a gallon of gas and keep an eye out over your shoulder for epa or deq while you're spraying...and no cigars while spraying!!

is this the same thing as Sta bil ?

Anyone ever put this stuff in the crank case of a vehicle? It says that you can. This stuff must be kinda like castor oil was back in the day...it's good for whatever ails ya.

No, different product.

I also use it in everything. I put it in my gas tanks, and oil. So far, so good.

I have been told to run Sea Foam in my 2 stroke boat motor, but can't find it anywhere. Where are you all finding it?
