The low fuel light is *very* conservative. My low fuel light comes on
at between 40 and 50 miles left until empty per the overhead console
computer. However, doing the math based on actual fuel mileage and the
24 gallon tank in my QC, I could theoretically drive about 20 miles
*past* where the computer says 0 miles to empty. HOWEVER, read on...

Just once, or regularly? Running dry is never good. Ignoring the low
fuel light regularly is double-plus ungood. Your fuel pump resides
inside the tank, and is lubricated and cooled by the fuel itself. Run
low and the pump will get warm, and will not be well-lubed. Result:
premature fuel pump failure. It's just easier to fill the tank when it
asks for more gas.

To what end? To figure out how many miles you can go? Instead, just
track your gas mileage using the time-tested pencil & paper "fill up
tank every time, miles driven divided by gallons pumped" method. Then
take that number (your MPG), multiply by 18, and use that as your miles
possible.
I say 18 because you want a safety margin.
