Non-ethanol isn't available around this area... As far as higher octane? In this area there are two stations, great, if you stay in this area, but I drive my stuff, not just around town, next Saturday we'll put around 200 miles on up in the hills, no race fuel to be found anywhere up there.... So, build an engine that can't leave town? That ain't happening... We plan our builds to run on the crap we can actually buy....
