My fuel gauge sensor started acting bad several months ago.
After the gas in the tank got below half full, the gauge
shows empty.
I buy my gas at an Race Trac station. Don't know where the
gas comes from, but either a Houston or Corpus Christi refinery.
It may not have been the fuel that caused your problem. When gas is bad, it affects hundreds and thousands of cars, and the common source is identified pretty quickly.
I'm in New Orleans right now. I topped my tank off my tank on 5-22 with 28 gallons of unleaded at the Bullard Shell station. My needle up till 5 minutes ago was showing a half a tank of gas with 180 miles on the odometer. Now it's showing 1/4 of a tank.
At least it's a work truck :-/
I get it at Race Trac too. My gas gauge has never worked all that well, but I don't think it's any worse right now.
