Hmm, I'm surprised Iowa hasn't mandated 10% only, given that corn composes about 95% of our economic output.
I will fill up at least 4-5 more times with unleaded to really know for sure.
It's probably a matter of pennies and dimes either way, but it still intrigues me. I'm actually hoping that the non-ethanol blend proves better, basically because I think the ethanol industry as a whole is a big joke.
