I still keep 20 gallon of gas (4 five Gallon cans) on hand for the portable generator wired to the old house. Until recently the only thing we could get here was 10% ethanol.

I start the generators every 6 months and run them for about an hour and end up burning the old gas 5 gallons at a time thru the ram 50. (Wait till the tank is almost empty pour in 5 gallons and then top it off with fresh gas).

At six months the gas is about at the end of it's shelf life and that was true even with the stabilizer, so I stopped spending money on stabil.

We now have a somewhat local station that sells non-ethanol gas so I'll probably try that next time as see how fresh it stays. 89 octane only and it sells for the same price as 92 "premium" E10.

Personally I'd ditch the "long term" barrel with stabil idea and just rotate drawing gas for from one barrel to the other so the current "standby barrel" always has reasonably fresh gas in it.

Just an old mans' 2 cents.
