    Bad Fuel Level Sensor or Horrible Gas Mileage ?

    here's my gas needle at 98 miles. . .

    26 miles later . . .


    it's on E by 200 at the most . could my fuel level sensor be bad or just burning that much gas ?

    Mine used to do that. Complete maintenance and non winter driving brought it up. Winter is 300 and summer is 400. Run fuel system cleaner, especially in the summer. You'll see 30 mpg, city.
    It may sound mean, but; Grow some balls.
    After my needle hits E, I can sometimes go for 100 miles.
    I've ran out twice.
    MRT
    37.5 MPG, AC on, cruising at 80.
    30.0 MPG, AC on, aggressively driving around 90.
    27.5 MPG, no AC, cruising at 90 with occasional gridlock. 40 degrees Fahrenheit

      Well this seems pretty simple to figure out. When it hits E how much gas are you putting into the tank? If you hit E after 200 miles and only put in 7 gallons obviously the sending unit for the fuel gauge is bad. If you put in 14 or 15 gallons(not sure exactly how big our tanks are) then your getting some really bad mileage.

      My wagon just averaged 25mpg and I was rodding on it now and then

          I filled up today at 217 : took 13 gallons soo its getting about 17 miles per gallon . I'm guessing that's not normal .

            It really depends on how you drive and the type of driving you do. If your doing all highway and not hitting WOT all the time then yea you should be getting better than 17.

            However if your doing mostly city driving and have a heavy right foot then 17mpg is probably about right

                    IS your car running rich or leaking fuel. If not then its just your driving habits and the area you drive. In my old celica I could get 24mpg for one tank and 14 for the next. it all depends on how hard you flog on it.

                    Same with my X-runner supposed to get 18-22 mpg and I never got better than 14. It was supercharged and I liked to have fun in it tho lol.

                    I never calculated the fuel mileage in my corvette but if it got/gets better than 8mpg I'd be shocked

                      The needle bounces back and forth all the time . I tried to run it out once to see how many miles I would get and I drove on E for about three days ( not a lot of driving ) but I'm not sure it ran out because I parked it one night , went to start it the next morning ( VERY cold morning ) and it wouldn't start . Put a can of gas in , started up but I'm not sure if it was the weather of if it was really empty . Gas light never came on , never has .

                        It runs really rich at idle , idles low while driving . No signs of fuel leak besides maybe fuel burning off somewhere in the engine bay ?? Smokes after 4000 RPM . I never really drive heavy , always shift around 3000 RPM .
