I applaud the Minnesota Street Rod Association for providing this list. I wish more states would do this. Of course Minnesota, along with my state of Oregon, is a mandatory E10 state and has a provision in the law to allow pilots to purchase ethanol free gasoline for aircraft use. But, be advised there is nothing in the statute that requires gasoline companies to provide ethanol free gasoline and as the federal RFS mandate squeezes the majors to blend more ethanol every year they are going to be up against a blending wall by the end of 2012 and many of them may quit making ethanol free gasoline.
Those states without ethanol mandates have no protection for aviation and there is no requirement in the federal RFS mandate for requiring that unblended gasoline be made available for aviation, marine, public safety, antique and classic cars, or small engine use, so there is no requirement for states to tell there citizens where they can find ethanol free gasoline, if there is any.
I gave a presentation at Sun'n Fun about the future of aviation gasoline and the problems of ethanol blending in all of the auto fuel and the slides from that presentation can be viewed at www.e0pc.com/SNF10.pdf
I urge folks to get involved before there is no more ethanol free gasoline made and urge their state legislators to pass a law prohibiting the blending of ethanol in premium unleaded gasoline. It is the only option you have if you want mogas to be available for aviation in the future.
