Was driving to the dealer to have another problem fixed when my fuel gauge droppped to zero and the fuel light lit up. Pulled over, restarted the car and everything was fine. Kept driving. Happened again then corrected itself. When i got to the dealer they said that there is a problem going around with too much sulfur in the fuel. apparently some refineries arent putting enough cleaning agents in the gasoline and it is causing problems with the fuel sensors in fords. They cleansed the tank and told me to avoid cheapo gas stations like sheetz, told me to use BP whenever possible. Any others have this problem? Any ford service techs have any comments?
