I noticed a 10% increase in mpg with non ethanol gas.
So here is the trade off:
Save 7% at the pump
Buy 10% more fuel

It really sucks in gas power equipment. I can’t tell you how many carburetors I’ve had to replace in mowers, chain saws, power washers, log splitters, snowblowers, etc. It eats away gaskets, diaphragms, and will absorb water. You have to add expensive stabilizers or your engine probably won’t start after setting for a couple months.
