Here in IN, we have stations that sell the premium cheaper because no one else buys it. They won't let it just sit in the tank, so I always fill up at the same place. I have bought gas at the same price as regular at least 6 times in the last 6 months, but she is stored in the winter, so it doesn't cost me anymore to drive the xf than my Mazda, and, and a big and, the xf matches the Mazda on fuel mileage, and it will out run just about anything that was dumb enough to screw with me, including our own police cruisers. They can't believe it. Everyone around here thinks its a cute little roadster. They don't know it can be a beast like the Vets I used to own. They think I am getting old and slowing down....Doc
