You had me curious because I’d always hear from mechanics otherwise, so I did some digging. According to this study (https://ethanolrfa.org/file/1793/Water-Update-Weathering-of-Ethanol-Gasoline-Blends-in-Humid-Environments_NREL_2016-09.pdf) it seems like it’s probably a misconception that ethanol free degrades slower, but it probably allows for ignition when stored longer due to the higher hydrocarbon content. Kinda a dull read, but that’s what I got from it. (Also. As with everything * take it with a big grain of salt. Your local municipality might require the additive of detergents or stabilizers in the fuel already, or might just add it to ethanol free fuel as a “premium” incentive. So who knows, lol. If it’s working for you I dig it.)
I use ethanol free gas in my mower. I’ve heard it’s stable for a year.
