Winter gas is a pain. I recently had some serious mileage dropoff. Switched to a better grade of gasoline, 87 to 89 octane, and all was better with the world. In fact, I ran a tank of non-ethanol gas through it first, which made an immediate difference in performance. Mine is the 1500 with the 5.7 though.
