E-10 is bad enough it will gum up parts, still is corrosive you get poor MPG with E gas, E-10 can be ran in any vehicle thats not carb'ed but your mile will suffer, I tried it in my 94 model truck and lost on average 5 mpg on each fill up. I have also seen waht E-10 does to a lawn mower carb, its nasty, rust because it has water in it, and attracts water, also had some white scale stuff in it as well, I always run 100% gas, if I have to run E gas its just enough to get me to where i need to be then run the 1005 gas to flush it out. If they the government forces this crap on us I will just go to coal burning diesel just to get away from this E gas nonsense junk. You know its bad when they have to haul it in stainless steel, let alone its so corrosive it eats metal parts.
There vids on the sepration of this E-15 even think E-10 does the same thing, I refuse to run any E gas period, unless i have no choice to get home.
