> I may be wrong, so if I am, correct me on this assumption. My problem with ethanol is that cars have to be specifically tuned and equipped to handle it. Now for new cars (Assuming they are built to handle x amount of ethanol) that’s no problem. What what happens to all the older cars still in use? I don’t have any plans or budget to revamp my entire fueling system/plumbing just to use ethanol. And it’s already been proven that ethanol mixed gas in cars that were not designed with ethanol in mind can and will suffer performance and efficiency drops. Yes folks, that means LESS fuel efficiency.

I think it can be safely assumed that the new regs apply to new cars only?
