If you can still get real gasoline (i..e. without ethanol), I'd strongly recommend that you keep using it for your small engines. Ethanol is hydrophilic (i.e. it will take and trap moisture from the air) and that is one reason it degrades much more quickly than pure gasoline (important if the fuel is going to sit for awhile in a leaf blower, can, etc). Also, that water will help rust out small gas tanks and carb parts. Lastly, many older engines of all types have rubbers and plastics (fuel hoses, gaskets, etc) that will break down when exposed to ethanol.
Ethanol is especially problematic for boats (because they tend to be near water, because they tend to keep fuel aboard for a long time, and because they have long normal service lives, so a disproportionate number are older and don't have ethanol-safe hoses and gaskets). Marinas can be a good place to find real gasoline (unadulterated with ethanol).
Rejoice that you can still get real gasoline, and thank the merchants that carry it.
