I run a small engine repair shop in San Antonio. Been in the industry for 20 years. I called ethanol fuel the small engine stimulus plan. We repair close to 4000-6000 small engines a year, mainly outdoor equipment. The majority of carb related repairs are due to ethanol jelly build up. In the winter we go to update seminars and all the small engine manufactures talk about the effects of ethanol on carbureted engines. Now the guys here never having any problems may have EFI or DI motors. I can see why these types of motors would have less issues with ethanol. But just because something has never happened to you, doesn't mean it doesn't exists. Cars go though fuel way faster, very rarely does gas stay in a fuel tank longer then 30 days. The system is pressurized as well.

Here is a fun experiment. Open your garage for ventilation. Put some gas in a open container with a wide mouth, like a measuring cup. Now let a box fan blow on it for about 2 minutes (less humid days require more time). You will see the gas get cloudy, this is moisture from the air being adsorbed by the fuel. Do the same experiment with ethanol free gas, you will see the difference.

BTW, you can get ethanol free gas in San Antonio. Murphy gas station on Pat Booker road and the one in Borne as well.
