The only apology that is needed in this posting is my apology to Creekbob. Sorry this resulted in a hi-jack of your original post.
I learn a lot about these cars from this forum. I am glad to be able to help out when I have information that can help others out.
As far as the ethanol, the scary thing for me is that states have different rules in what they have to label at the pumps. I happen to now live in Wisconsin that has to label any ethanol at any percentage. I used to live in Michigan which is not required to label anything at all. Other states have to label it over a certain percentage.
In the link that follows, you will find a listing of states that require labels and for what percentage. This is not an advocate for anything else on the website, just useful for the chart. Maybe one of the moderators can take a snapshot of the chart and make it a sticky somewhere.
