[QUOTE="jmstekguy, post: 16584886, member: 67054"] We have ethanol free 94 octane, 91 octane with ethanol 7-9%, and 91 with 10% ethanol. I try to use 94 exclusively for now but have had multiple cars show light knock (coyote cars) with the same fuel and no changes from when it didnt knock, just a tank fill up. I always leave the Borderline spark tame and dont go after the last 2-4% for safety sake of the fuel differences. [/QUOTE]
