I agree with Don. All of my lawn equipment and older vehicles get non ethanol (usually 87 or more octane). Putting ethanol gas in older vehicles and small engines is looking for trouble.

Only if the vehicle sits for long periods of time not being driven is ethanol a problem. I've been using ethanol fuel in my '56 Cadillac since it was mandated in Atlanta in 2007 or so.
Aside from ethanol destroying the original fuel pump, everything has been fine since. I use my vehicles for everyday driving so fuel doesn't sit in them long enough to cause trouble. The AD turck has been driven almost exclusively on ethanol fuel since I rebuilt the fuel system. It has nearly 3000 miles on it without problems due to ethanol.
I'd prefer non-ethanol fuel but I'm not driving all over Hell's half acre to get it.
