In FL, almost all gas stations use E10, now I heard the feds approved E15. Any impacts we need to be aware of? E15 ethanol approved in US for 2007+ model years: critics, supporters react : Biofuels Digest - biofuels, biodiesel, ethanol, algae, jatropha, green gasoline, green diesel, and biocrude daily news But I did read this..."However, no waiver is being granted this year for E15 use in model year 2000 and older cars and light trucks – or in any motorcycles, heavy-duty vehicles, or non-road engines – because currently there is not testing data to support such a waiver." How in the heck will gas stations have all these different blends... Seems nuts to me, but who knows. Ride safe and have fun!
