They aren't selling winter blend fuel down there already, are they. I've notice a decrease of about 1 mpg in my last two tanks. I attributed it to refueling at a different stop.

gotagoat, Do you use a fuel additive? If not, you might try some for 1 tank. Things I would check.... 1. Fuel filter 2. Air filter 3. Lift pump pressure 4. IAT sensor 5. Map sensor

Check you crankcase oil with a Vis guage or have a sample done to see if you have fuel in the oil. You can try smelling it also. Crankcase could go boom, if its full of fuel. Thats the only leak you would not see. Like the other replys, may be the fuel or lack of centane in the fuel that is doing it. Dave
