I try and carry and use real gas in my snow blower because of the intermittent use, and sensitive nature of the carb on it. It clogs easily and quickly when left idle, despite the type of stabilizer used with blended fuel. I hate it when it starts doing the low power surge meaning I'm going to have to pull the carb. It's hard to get to on that engine.
On my two little inverter generators I use real gas when I can, again because of the intermittent nature of use, often sitting for months, with wide temp swings, which break down e-10 quicker as well. I've seen it start gelling etc in only a couple months in some conditions. The other reason for the real gas is the small, but noticeable power difference. Much of my camping is at altitude, with only longer road trips getting me below 4000 foot. I see 8k plus often in the summer and it's somewhere around 8k when I might have to parallel the gens to run the microwave, which draws 1500 watts. Real gas gives me a power difference equivalent to approximately 1500 feet or so which sometimes is enough to make the difference. Not much, but you can definitely see it, especially with two generators where you can do comparisons.
My cars, atv's and lawn mower aren't fussy so they get what's cheap, and easiest to procure, and E-10 would completely destroy the truck so of course I don't use it there;)
