Why car starts stalling in near empty gas tank Around 15-20 of gas remaining in tank?

Answer 1

Any car will stall going around corners with only about 1 gallon of gas left in the tank (15-20 miles). A car should never be driven that low anyway as most modern cars have in the gas tank electric fuel pumps. The gas is actually used as a coolant for the fuel pump and if the car is driven too often down to the dregs of the fuel tank the fuel pump will prematurely fail due to overheating. It's a bear to replace the in tank fuel pumps on most cars. Also, it's not good for your gas mileage either to run the tank dry on a regular basis. Most fuel gauges are not all that accurate so when the gas gauge comes just to the "E" there should be about 2-3 gallons of gas left and you shouldn't push it beyond that. You should actually not drive past a quarter tank if at all possible. If you want to get a rough idea of how your fuel gauge is calibrated on a new or new to you car, fill the car completely up with gas. If the gauge reads much over the "F" (such as up to a quarter space on the gauge if it were marked past "F") you will most likely run out of gas right when the gauge hits "E". If the tank is completely full and stops at "F" without going past, you will usually have a small buffer at "E" before you completely run out of gas.
