if you can afford to fill the tank as soon as the light comes on, you know you have like a 17 gal tank, so just do the math, but as said before its no science and may come on due to a sharp turn or hard stop as the gas thats left shifts in the tank and the float reacts to level changes.

my last truck had a 34 gal tank, when the light came on i had 4 gals left, @ 10 miles to the gal i knew i had at most 40 miles worth of driving left.
