Used to be (when gas was this low in price couple years or so ago) the separation between regular, mid, and premium, was only @ 10 cents each. Now they are FRACKING ridiculous. Doesn't cost any more to make those same grades, its the market that is driving that high a separation. Oil going down, octane ratios vs regular are through the roof and most likely going to get worse the more cars/trucks that use 91/93 octane. Rant OVER!
