Just a bit of info. I haul gas for a living in Alabama. As far as normal ethanol gas goes.(not e85) dont buy mid grade!!!!! Its identical to the reg w/ ethanol. Theyre both 90%reg 10%eth. Just dropped into different takes…. Prem w/eth is 55%prem, 35%reg and 10%eth. The high percentage of reg in prem is to dilute the ethanol to bring the extra oct of the ethanol back down to 93 octane. Ethanol is something like 130-140 octane. Cant remember exactly. So save youre money if youre buying midgrade w/ ethanol!!! Just get regular.
