Apparently AAA thinks we should be concerned about using E15 fuel in our vehicles (unless our vehicles are in a select group of newer vehicles - 2013 Fords for instance).

Also, is it required by federal law to label pumps containing E15 (for instance, I live in a state (Michigan) where it’s not required by state law to label E10 fuels).

How are we to know what amount of ethanol is in our fuel or doesn’t it matter because our government (always) has our best interests in mind?
