For anyone using small engines such as saws, pumps, weed eaters, etc. Try something like True Fuel ( Home Depot) or Stihl Motomix. Both are 92 octane with no ethanol, premixed 50:1 and had stabilizers. This stuff works awesome in small 2 strokes. Easy starting after sitting with no use also. Don't have to worry about gaskets and seals rotting with the ethanol. I use it at home and work.
As for e85 (85% regular/ 15% ethanol) as it's called around here, it's garbage like everyone else says. Even with flex fuel calibration, still not worth it.
