FUEL GAUGE IS NOT CALIBRATED PROPERLY AND APPARENTLY CANT BE. THE EXTENDED CAB S-10 LS MODELS HAVE 19-GALLON GAS TANKS STANDARD. THE GAUGE READS FULL WHEN FULL BUT SEEMS TO GAUGE MY FUEL CONSUMPTION FASTER THAN I AM REALLY USING IT. IT WAS MOST CONCERNING THE FIRST TIME THE LIGHT CAME ON. I THOUGHT AT FIRST I WAS GETTING ABOUT 13 MILES PER GALLON WHEN HALF OF MY DRIVING IS HIGHWAY. WHEN THE GAUGE GETS DOWN TO THE 1/8 TANK LINE THE FUEL LIGHT COMES ON. WHEN I GO TO THE STATION THE TANK WILL GENERALLY TAKE ONLY ABOUT 13 GALLONS MEANING THERE IS 6 REMAINING IN THE TANK. IT HAS BEEN CONSISTENT SINCE I BOUGHT IT AND OVER THE ALMOST 40,000 MILES IVE DRIVEN IT. I STILL DONT TRUST IT COMPLETELY AND USE MY TRIP METER TO GAUGE ITS ACCURACY. GENERALLY I JUST MAKE IT A PRACTICE TO REFUEL WHEN THE LIGHT COMES ON. I KNOW I HAVE ABOUT 3/8 OF A TANK REMAINING WHEN THAT OCCURS. *CB

GAS GAUGE IN MY TRUCK HAS BEEN ERRATIC SINCE DAY 1. I HAVE BROUGHT IT BACK TO THE DEALERSHIP NUMEROUS AMOUNTS OF TIME. I THOUGHT IT WAS LACK OF KNOWLEDGEMENT FROM THE DEALERSHIP SO I BROUGHT IT TO ANOTHER GM SERVICE GARAGE AND THEY TOLD ME BECASURE OF THE DESIGN OF THE GAS TANK THEY WOULD NOT BE ABLE TO FIX THE PROBLEM. I HAVE RUN OUT OF GAS TWICE AND ALMOST HAD A SERIOUS ACCIDENT ONCE. THE NEEDLE READS FINE U7NTIL IT REACHES 1/4 OF A TANK AND THEN IT DROPS TO EMPTY AND THEN YOU ARE ON YOUR OWN. WHEN DRIVING DOWN THE HIGHWAY AND THE NEEDLE REACHES 1/4 OF A TANK THE NEEDLE DOESN'T MOVE UNTIL YOU COME TO A STOP AND THEN IT DROPS TO EMPTY AND THE GAS GAUGE DOESN'T COME ON TO LET YOU KNOW THAT YOU ARE LOW ON GAS. I HAVE HAD IT WITH THIS TRUCK AND THE DEALERSHIP. PLEASE HELP !!! I LET THE 1ST DEALERSHIP TAKE MY TRUCK AND DRIVIE IT BECAUSE THEY SAID THAT THEY COULDN'T DUPLICATE THE SAME PROBLEM THEY PUT 400 MILES ON MY TRUCK AND SAID THAT THE GAS GAUGE DIDN'T DO WHAT I WAS SAYING. I DROVE IT OUT OF THEIR YARD AND WENT 15 MILES AND THE TRUCK DID WHAT I WAS SAYING IT WAS DOING. I THINK THAT I HAVE BEEN MORE THAN PATIENT WITH THIS GARAGE.
