That is a good read. When I worked for the state motorcycle program, we were constantly dealing with ethanol issues. We used a product called Pri-G that seemed to work really well, even in old gas. Diesel version is called Pri-D. See what they did there? But I learned even more in that article. Thanks for sharing.
