Fuel Mileage Range

[LSCobalt]

This morning the fuel mileage range display indicated 38 miles. After driving a few blocks I got the Low Fuel message. I drove to my preferred gas station -it's never crowded - and filled up. I checked the display and it only showed 280 miles. Ever since I bought the car, the display always showed about 425 miles after a fill up.

Is it time to have the fuel sensor replaced? The fuel gauge needle seems to be functioning correctly.


Thanks for any input

I doubt it, it calculates ranged based on your current average MPG x gallons in tank. I bet your current average is just lower than normal. Rest the average gauge on the fly and range will recalculate.

My average is usually around 40 mpg, 43 today, when I fill tomorrow it will say I can go about 540 miles on the tank.

Playing with resetting MPG on the fly this morning, I could only get the range to up 2-3 miles but have less than 2 gallons of gas in the tank, just over 500 miles on tank once I got to work.
