We're headed south (AZ) again, and will be living on generator power for the next couple months. I thought I better drag out the little 1K watt Honda generator that hasn't run since Mar last year. Tank was full of e10,.....no additive of any kind. Full choke and 5 pulls of the rope, sounded good, loaded it w/ 750 watts, (heater) runs like a new one.
My point,......I still find no ill effects from e10. I know, tell you something I didn't before
Curious, ?.....In 2 months time, I run about 15 gals of e10 thru this little Honda every year.
