Stabile will keep gasoline with ethanol ok for a month or so. I use Startron fuel stabilizer(it is the blue stuff).
No, there are not any local stations, within 30 miles that sell regular octane non ethanol fuel. There is one Sunoco that sells 100 octane racing fuel at $8/gallon. I buy that for my chainsaw and other two stoke engines.
The only stations in NH that sell non ethanol regular octane fuel are a couple marinas up on the big lake about 50 miles north. There are a couple small airports that sell aviation fuel.
A MONTH?
I have stored gasoline over TWO YEARS with Sta-Bil and Pri-G, and have had no problems with it, ethanol or no. Now, when the price is cheap, I do try to get ethanol-free gas for storage, and I buy it in January, when the volatiles are at their max in the mix.
