AAA warns E15 gasoline could cause car damage
"E15, a higher blend of ethanol and gasoline, has rolled out in a handful of states. But its use in older vehicles is generating warnings from AAA, which says E15 could be harmful to pre-2012 vehicles."
Has anyone run into this as an issue yet? Of course, Cobra's have engines that are not 2012 versions in a lot of cases - most cases, so if E15 is the only option - just fill it up?
