I have a 92 pontiac bonneville se. now, like many people. i never fill up my car, so the gas light comes on often. i was wondering if anyone knew how many miles i could get in my car once it comes on or when the gas gage goes into that shaded rectangleish thing by the E on the gas gage .

thanks.

Next time it gets that low, fill it right to the top. Your fuel capacity is 18 gallons, so if you subtract what it takes to fill it right up you will know how much gas was left in the tank. If you put in 16 gallons, you know there was still 2 gallons left in the tank. Record your mileage.

Next time you need gas, fill it up one more time and use the amount of gas you put in and the miles since your last fill to calculate your miles per gallon.

If you are getting 20 miles to the gallon, and hav 2 gallons of gas left in the tank when you hit the mark on the gage you are referring to .....

Let'* talk about never filling your car up. That means you are fueling often and putting in small amounts. Why not fill right up and continue to fill often and putting in small amounts. Keep your tank at the top end, not the bottom. This will reduce condensation in the tank, and give you a reserve when you have a ways to go between gas stations. Other than the initial investment to fill it, it won't cost any more money to run it that way.

you won't get much i had a 1992 se and at that point i could only go about 10 miles intil i died.
