Hey raising an old thread from the dead. I like that. I'm a sea foam guy in all my small engines. Right or wrong it's always seemed to work for me!
I have many small motors that i use plane old pump gas with 10% ethanol for many years and sometimes leave them sit with fuel in the tank for months.
I never have had a fuel issue. Not even once.
You can get ethanol free racing fuels that you can buy at most motorcycle shops or dealerships.
Race fuel burns at a higher temp, burns longer and burns more completely, giving you more power per stroke.
And with an octane of 105 it gives you more power then pump gas.
I use VP U4.4 or C110 race fuel, and been using it for years.
Pump gas will tend to cause my saw to bog down under a load. Race gas keep it from bogging down and give you more useful power.
And I live in a high humid environment where the ethanol will absorb the humidity from the humid air.
Two stroke oil mixed with gas will last several months before going bad.
I also have a 200 gallon fuel tank that I keep full for storm fuel for my generators. It can sit for 90 days before I start using it, and still no issues.
I do ad a marine grade stable additive in the big tank, just because it may sit for some tome before I get around to using it.
A good carbon fuel cleaner is also good to run through every once in a while.
I have an old weed eater that sat for 5 years with old mixed gas that had been sitting in the weed eater all that time, and she cranked on the second pull.
I think the fuel controversy is a lot of hype for mechanics to sucker people into more work. ( women are big targets for this scam)
Also adding a small amount of automatic transmission oil to your fuel will keep the carbon build up from happening. I put about 16 oz to every 20 gallons.

I do the same. Just pop some Stab-bil into the gas cans before I fill them.
One helpful tip in humid areas, is to keep the gas tank full.
With the temperature fluctuations throughout the day, any air pockets in the tank will let air go in and out through expansion.
The humid air comes in and condensates in the tank and sinks to the bottom, or in the case of ethanol, will mix with the alcohol and you end up with water in the fuel, witch will reak havoc on your carb.

a good way to revive dead gas dump a full can of berryman b12 to 5 gallons of gas it has enough toulene and acetone to wake it up so it will burn better.

Wood's Tougher Than Woodpecker Lips...
Use Star-Tron stabilizer and a couple of capfuls of Sea Foam in all my straight, non ethanol gas cans and pre-mix cans for all my OPE. Zero failures in years.
Gasoline can and will go sour... no rhyme or reason to it.
I tried to start my splitter last week that had been sitting for about 5 or 6 weeks with a full tank of non-ethanol pump gas. It wouldn't even pop, and after a half dozen pulls on the rope I could smell the bad fuel coming from the exhaust. I took the cap off the tank and it smelled fine... so I drained the float bowl (that fuel smelled real bad) until the fuel in it was replaced. It started on the second pull... just the fuel in the float bowl was bad, the fuel in the tank was fine.
A couple years ago I had a full tank (6 gallon) of 91 octane non-ethanol go bad in my generator... that fuel was less than 2 months old and had been treated with fuel stabilizer. It was so bad I couldn't even get the generator to start... not even a sputter. But, the 91 octane non-ethanol I have in the generator now is nearly a year old, and the generator pops right off every monthly test run.
The generator is the only thing I use a fuel stabilizer in... and I use no additives of any other sort in any of the other dozen or so small engines.
Any quality two-cycle oil already contains fuel stabilizers, so does the gas you buy at the pump (all additive packages contain stabilizer)... and ethanol blended gasoline contains more stabilizers than the non-ethanol. If you use a quality two-cycle oil there ain't any need to add anything else... it won't hurt anything... but there ain't any need.

Wood's Tougher Than Woodpecker Lips...
Cranked my saws up this afternoon, as well as my two generators. Just to give them a little idle, run time, and burn some fuel. I'm gonna stick to my guns, the Star-Tron and Sea Foam. Pennies on the dollar for 'added' protection...I'm all in. Juss sayin.

About a month ago I ran my generator until it ran out of fuel that had been in it for over a year. I used a stabilizer and it clearly worked. I'm a big fan of non-ethanol gas for all small engines.
Try VP fuels, They come just about any way you could want, Ethanol, leaded, unleaded, high/low octane.
Been using it for many years.

I am fortunate enough to have this locally.
How do you know it clearly worked??
Did you store some of the exact same fuel untreated with stabilizer and compare the two??
Listen... I ain't sayin' it didn't work, but there ain't any proof it did neither.

I guess you're correct on that. Let me just say I expected a problem because it sat for so long but it started right up on the second pull and ran without hiccup until there was no more gas. It convinced me the stabilizer was doing its job.

i use pri g it is the only one i have found that works you can mix it in a can of ethanol free and come back to it in 3 years still fresh its keeps E10 fresh for 18 months.

'Pri g'??...can you expound a little more?
http://www.priproducts.com/pdfs/PRI-G For Small Engines Brochure.pdf
That should help.......I've used this, seafoam, sta-bil. Figure none can hurt, haven't settled on any as "the elixir".
Gas pumps are required to have a sticker that says it "MAY" contain up 10% ethanol. It doesn't mean it has ethanol in it, but that it may.

I've also used PRI-G for years. Normal E10 with PRI-G, stored for up to 2 years in steel jerry cans works just fine in our mower, cars, and generators. Haven't tried gas that old in any saws, though.
