sea foam

Its the best as far as im concerned. will usually cure up a bad tank of gas, its also better for storage than sta-bil. I use a can every couple months in each car. I use it in all the small engines and the outboard and have virtually no gas issues. 6.50 can at farm and fleet or menards. too high at any auto parts store . good luck

Yup, I used to have to clean carbs after the tractors set for long periods of time. Sea foam works great i don't have to do anything to them but i always ran gas that did not have ethanal. now that i can't get ethanal free gas i try to run them dry before i store them. I still use sea foam.

I have put sea foam in my F-150 and have not had any trouble. Can't get anything that doesn't have ethanol in it where I am in Kansas. Normally, I keep the tanks topped off on my tractors.

Yup works great!

Interesting, guys not liking alcohol in gasoline but like Sea Foam. It's main ingredient is Isopropyl Alcohol...

I buy it by the case when I have the chance cause it works so well. I got turned on to it when I worked for a small engine repair shop. We would have a lawn mower running rough and little of that magic in a can next thing you knew that motor had smoothed right out. Best you can buy in my book.

Some additives will, under the right conditions, help break up crud from carbeurators, clear jets, float valves, and residue build up around air bleeds.  I have a can of SeaFoam, as well as a bottle of Marvel Mystery Oil, and some Sta-Bil.  Generally, I find that if I run the gas out of a fuel system before putting the machine in storage, I don't need any additive to clean anything out, but when faced with a pesky situation (say, one float bowl sticking on the motorcycle), one of the additives will frequently clear it... but many times, I just take it out and run it... pulling fresh fuel through oftentimes does just as well.

The ONE thing that I've always made habit to do... is fill every tank to the top with fuel refined AFTER the fall changeover in formulations.  Summer formulations are tailored to reduce evaporative emmissions, and don't store as well, for as long as winter formulation.  I also try to avoid putting ethanol blend in a fuel tank that will be in long-term storage, as the ethanol WILL settle out and stratify, it will absorb moisture, and when you go to start the engine, the very first fuel going in, will be water... followed by water and ethanol, then ethanol, then yukky gasoline.  I bite the bullet, and drain the (full) tank out into a recovery tank (easy to separate out the water, then circulated it into my 300gal overhead tank so that the ethanol isn't concentrated) and refill with new gas before firing it up.  Also, by keeping the tank full, there's very little airspace within which condensation can occur and fall into the fuel.

In my opinion, the #1 BIGGEST argument against ethanol blending, is that ethanol blend fuels, when left sitting in ANY tank for extended periods of time, WILL settle, and you'll have layers of water, saturated ethanol, straight ethanol, ethanol gasoline, and topped with old gasoline.  When you run that engine on saturated ethanol or straight ethanol, LOTS of nasty things happen which manufacturers deny.  Anyone who claims that this DOESN'T happen can easily be disproven by taking a glass flask full of ethanol blend, capping it with a vented lid (just like a fuel tank) and leaving it sit on a shelf in a barn for 6 months.  At the end of the test, you'll see layers.... take a sample bulb and withdraw a sample from each layer and give it a lab test.

Isopropyl Alcohol is made from wood/grain, Ethanol is made from Corn and is heavily subsidized by the Government. Forgive me, I know this is a topic for a different forum, but he asked... :-)

I top off the tanks in the fall and add a can.  I also use it it the ATV's.  Anything that's not ran on a regular basis.

Suck Seafoam into the fuel line on a carb that isn't running right, shut it down with the Seafoam in it and let it sit.  A lot of times that will cure the problem.

Try the SEA FOAM pennentrant works darn good as most of their products do. It has capillary action to it, about all I use any more.

I have always been skeptical about SeaFoam and Marvels Snake Oil, but with all the equipment storage issues I've had in recent years associated the bullshi* vodka-gas blend they sell now I've started to try anything.  I started adding stabil, the enzyme ethanol gimmick, and marvels snake oil to every 5 gallons I bought.  

I've never heard of sea foam, and I've never had any fuel issues either.
