Far as I know here in Australia it is illegal to sell regular fuel without identifying if it has ethanol content (there's a price difference between regular and the blended E10 stuff) but no doubt it has been cut by the corporations to make money as there's no fuel excise levy on ethanol. I avoid running it in anything now as it has a bad reputation for causing all sorts of grief. You can add a fuel stabiliser to the tank if you know it's going to be getting on and off use.
use sta-bil marine ethanol treatment in all of your vehicles - it negates the effects of ethanol in your tank. I run it in all my cars and it makes them run much better. My 92 Prelude mpg went up 3-5 mpg when I run it in the fuel.
I am highly suspecting that ethanol is deteriorating the finger prime-pump on my chain saw (it’s dissolving) and the fuel cap gasket. I’ve heard horror stories about ethanol.
