15mpg on my ST wtf? Options

[mikecelica]

i recently was tryna do my gauges and broke the pointer for the gas gauge and the little ACTUAL NEEDLE that is inside a lil motor which controls the fuel gauge. anways i couldnt fix it and now my gauge is broken but after about 300km = 190miles , the gas light comes on. so do the actual needle and whatver controls the gas light work together as in if one gets messed up so is the other or no. cuz it cant be possible im gettin half the fuel economy i shud be getting. my car is pretty stock, i checked gas tank and lines no leak anywhere..??? THANKS FOR ANY HELP.

i think an st holds more to 14.5 15 gallons.

my fuel light comes on a 1/4 tank left... and that gives me another 120 or so miles. never ran outta fuel.

i just note the trip milage when the light comes on, add 100, and get gas when it gets there

seems like something may be setting your gas light on sooner than it should be
