Ethanol is just another way to rip off the buyers. Yes if you have a motor that is set up to run 100% ethanol then it is good but it takes like 3 gallons to go 1 gallon of gas. It all so screws up anything rubber. Where are you going to get crank seals that hold up and are not rubber????
Some years ago I was in ND on my motorcycle and they had HIGH percentage of ethanol. Where I was going 160 miles per tank but with all the ethanol in the gas I was having to stop at 100 miles. If you want performance you want to run methanol.. So other word you better get a MUCH bigger fuel tank as well.
