Gas additive quandry?

Re: Gas additive quandry?

Several people have made that recommendation around here. Why?

Seafoam is an engine cleaner / decarbonizer. It is not designed to stabilize gas. If it works in that regard too, why doesn't the manufacturer tout that as an added benefit?

if you read the can it says STABILIZER , plus one for seafoam!

The can will say anything they want it to say. Again, how does naptha, isopropyl alcohol or pale oil STABILIZE your fuel?

Re: Gas additive quandry?

I don't know Bruce, I'm not a petroleum engineer nor an OB OEM that can afford to fool around with half dozen kinds of cleaners with different quantities and not have to worry about getting it wrong. Peace of mind is worth a lot more to me than the palsy $8 I pay for a pint especially with the results I get.

And yes, My little garden tiller is a little 2 cycle Mighty Mite or something like that and this disbelieving redneck experienced bad fuel in it back when I was starting to pay attention to fuel additives for long term storage. Started the SF and no more problems even though I use it in the spring and don't change the gas now before I use it.

So, you are asking the wrong guy how does it stabilize fuel.

Re: Gas additive quandry?

Fuel separation won't happen if water doesn't get in. This is true even if no additives are used. I personally don't believe any additive is going to stop separation if water gets in. To prevent separation, make sure cap gaskets are good, cap is tight, and in my opinion, fill the tank before long term storage. That last one people argue about but that's my position.

Then there's the air vent. You recommending blocking that off too?

I store with 93 octane over the off season, because fuel loses octane over time. Starting with 87 means she fires up at something less than 87 next year. I also add Stabil.

Re: Gas additive quandry?

I use Marine Stabil in mine for storage and Seafoam during the summer months when we are at the lake. I to think Seafoam is a great product but I've never used it for storage.

It hasn't been mentioned here but I think I'm going with Formula X2. If you want to see a demo click on link below.

Re: Gas additive quandry?

SeaFoam is a mixture of naphtha, isopropyl alcohol and pale oil per the MSDS....that's it...nothing else. What in there do you think is going to stabilize your fuel?

I can answer this.

Answer: The proper amount of naphta, isopropyl alcohol and pale oil.

No. filling the tank reduces the amount of air in the tank and the surface area of the inside of the tank to prevent condensation forming inside the tank. Basically leaves no room for cindensation to take place

Merc says do not block the vent.

Take a look around on the Internet for this. There are a couple of boating forums where people asked "is this stuff any good". Some of the responses included the MSDS sheet for this stuff which stated the main component in it is ethanol. Mysteriously, the MSDS from the Formula X2 website has disappeared.


Furthermore the host of that show is a complete dope on this subject matter. Water in your fuel isn't going to "explode pistons". A quart of water dumped into the carburetor throat will do this but not water in the fuel. And also saying that high ethanol fuels burn hotter.... Wrong again. There is less energy in ethanol, hence everybody who uses E-85 flex fueled vehicles seeing a 30% drop in fuel economy. Looked like the host for ship shape was as much of a salesman as the guy with the X2 shirt on.

Re: Gas additive quandry?

This thread is quickly going the way all the additive/non-additive big bad ethanol threads go.

Long and the short of it, nobody makes a product that stops moisture collection in the tank. Read the bottle of StaBil "Ethanol Formula" it even specifically states that it won't stop any ill effects from moisture in the tank (not sure what makes it any different from the original StaBil other than it's green and more expensive).

If you want the least likely chance of problems with your fuel, use a good fuel stabilizer (not a cure all like seafoam), fill the tank FULL, and change fuel/water separators annually.
