Non ethanol or not ??

So the main difference as I understand it is the ethanol in the fuel. Like triple r was saying it's fine if you drive it all the time and you run it through but letting ethanol set attracts moisture and then that moisture is what does damage to small ports in your carburetor and stuff like that.. and that generally happens if it's left in a place where there's a lot of moisture. If it sits in a dry weather control garage probably not going to have as many issues as if it's outside or in a non-weather control garage... I don't drive my stuff as much as I would like to so I generally tend to put non-ethanol gas in it so I don't have issues. I absolutely use it in all my lawn equipment and stuff because it will sit all winter long in a moist storage shed...
Now as far as my personal experience goes with 11.5: 1 which is pretty close to where I'm at I can run 92 93 octane and it will run fine but it will diesel when it shuts off. If I just add a half gallon of race gas or a gallon of race gas to 5 to 10 gallons of generally non-ethanol 92 I never have any problems.... It tends to like just a little bit more than 91 or 92 I think we get 91 here...
