Ethanol will suck water vapor right from the air, and emulsify it easily over time. It's possible your neighbor keeps his fuel in a dryer local 'climate' than you, and possibly he keeps it better sealed against humid air.
When I keep Ethanol fuel in a gas can(rarely) I keep it in a well sealed 2Gal metal container. I also keep it fairly full, with a sealed top, and in a location where it isn't subject to a lot of direct heat or sunlight.
All access between the surface of a liquid like Ethanol and the absolute humidity(not standard humidity) around it will have a significant effect on how much water vapor is drawn by the Ethanol. Rel humidity is the saturation level, and the conditions for emulsion are greatest in the highest relative humidity, but the absolute humidity determines the amount of water vapor that can be absorbed.
Short answer - keep your Ethanol fuel sealed up in a dark place in a metal can for best results.

We actually store our equipment almost the same way - small stuff in a shed and the lawn tractors outside with a cover. Gas is kept in those red plastic containers (although mine is one of the old skool containers and his is newer).
He also mixes his own 2-cycle fuel and never has any issues, buying the cheapest oil be can get. I always buy the canned stuff for 2-cycle but I still drain it after use cuz I'm paranoid about cumming up the carb.
