Best gas to the Rockies and New England, poorest to flat old warm Florida where I live. The idea is to provide the bare minimum that the vehicles will run on (Read improve corporate profits). Back in the old days when I ran my Beemer from Florida to Maine in two .days, I would always experience 2-3 MPG increase when I hit VA and North The reverse was true on the return trip.

Same happens here in Europe too.
When traveling from Rome towards the Alps, I am accustomed to... 400 miles before I need to fill up.
When returning southbound, I easily get an extra 50 miles on the same gas tankful
Now, going back to regular vs. premium, what I can say is I've noticed that premium has more bang to it, so I generally fill up with premium for long trips, and leave regular to city traffic... after all, if you're stuck in 3rd gear in city traffic, what's the point?
