So i was driving today and ive never got the gas tank low enough for the low fuel light to come on, so i decided to test it to make sure it still worked. The gauge was basically on the Yellow part of the gas gauge and the car had about 255miles on that tank and the Low fuel light came on. So when i i drove the Pump to fill it up i had to wait a little behind this other guy and the low fuel light went off. When i filled the Car up the car took 14.3 gallons of gas. The fuel tank is a 17.5 gallon tank on a 2001 Pontiac Grand Prix SE 3.1 V6(my Car). So i guess it came on when i had about 3 gallons left in the tank, i thought it was supposed to go on at like 1 gallon with about 20miles to go until out of gas. I had about 60miles left in my tank before i would run out with the low fuel light on, that seems a bit high for a low fuel light, just curious here. Any help appreciated thanks
