Plus, just how many of the cars currently on the road in America can actually USE ethanol anyway? I live in Northern California, and I have yet to see a pump dispensing ethanol in my state (I do not argue they don’t exist, but I travel a pretty hefty portion of major interstates, yet I’ve never, ever seen ethanol for sale).
Ethanol is mixed with gasoline. I suppose you could use it alone (maybe with a sterling engine or the like).
nor I, however I often drive out to a country station (NC) that caters to farmers and rural types and the pump does say “10% ethanol.”
