“....how much gets dumped on the ground because it goes bad so quickly?”
Right you are. You can’t keep Ethanol gasoline for very long. You have to use it up. I can’t help thinking it’s intentional to keep us from being prepared. We can’t fight back if they have all the energy, and the ammo.
Sta-bil.
I use it in a 55 gal barrel with a hand pump.
At the start of the grass cut season, I use my credit card that gives me 15 cents per gallon off, fill up the barrel, add the right amount of Sta-bil (the cost of which is offset by CC discount), and I've had no problems from about the first of May to the middle of September.
55 gallons seems to be just the right amount for my 54 inch cut 26 HP Kohler, cutting nearly two acres of lawn.
Done that several years in a row and have yet to run out or have bad gas problems.
Well, I've had bad gas a time or two, but not from the treated barrel.

I buy all my gas ethanol free now.

One can still get Regular leaded Gas but Ya gotta look for it. My Brother has a place a few miles from the house and that's what He runs in the Boat, I got a place in Old Downtown that sells it.
