E10 Ethanol Gasoline

I use seafoam in everything, mowers, generators and all vehicles, great stuff! Walmart has it.

And how many gallons does it treat? My tank holds 30 gallons. And does it bring back the fuel mileage that the ethanol crap takes away?

the sta-bil pictured is 1oz for 10 gallons of fuel

I have sta-bil. I was asking about the Sea Foam stuff. If it's worth the price, I'd give it a shot, but at $8-10 a bottle, it better at least improve my mileage enough to offset the cost.

for clean out and the first time I dump the bottle in for 12 to 26 gallons then do the reg maintence they tell you too.
