Problems with E-10 seem to occur in particular places in the US, but certainly not everywhere. Problems seem to be more prevalent in very high humidity areas that have high condensation (and dew) when the temp drops below the dew point (happens frequently in Eastern NC, as my neighbors will attest).
EPA regs regarding gas tanks and motors made more recent motors more susceptible. The size of the motor is also important. My 5hp Honda, even though a 2001 model, has problems with E-10 or not, just because any impurity will clog the tiny passages in the carb. Where my 115hp Suzuki might cough but keep running at reduced RPM if I don't run it at high RPMs on a monthly basis, the Honda 5 would quit and not start until the carb was cleaned again. Even after being run dry after every time it was used.
Older mowers and other small gas engines generally run fine no matter what, but 2020 and newer Briggs & Stratton engines can't be depended upon to start. And automatic chokes make things worse.
I have switched to non-ethanol gas except for the autos. And use Stabil to help. Running an engine at least once a month at higher RPMs seems to make a big difference at keeping them starting and operating as intended.
Note I never had any problems in Colorado, California, or coastal Alaska except that carbureted 2 stroke small engines were hard starters at altitudes above 5,000ft.
