Central GA is awesome— can get E0 in 87, 89, 90, and 93 octane within 10 minutes of our home, currently between $3 and $3.20 a gallon.
All the boats and OPE get E0 90 octane, sometimes with a mild dose of Stabil 360 marine if I think it's going to sit around a while. 2-strokes get the same + regular Echo oil mixed at 50:1, the combination of fuel stabilizer I add and that which is in the oil keeps that gas fresh for a surprisingly long time.
The car gets E10 93 octane, half the time top-tier Chevron, half the time whatever is cheapest. The truck gets E10 87 octane from the Kroger station, because we get discounts...except when we're towing, when the truck seems a little happier running E10 89 octane.
