How Far Can We Go?
Before I got reliable numbers on our new toy I was worried about running to Empty. I even stopped for $20 of Diesel when I was only 20 miles from home and I still had 2 bars out of 10 on the fuel gag...

I haven't yet done it to this one, but for all the vehicles I've owned I have literally run it dry on purpose just to see exactly what it takes to fill the tank.
Also I like to see just how accurate the fuel gauge is, and most of them in my experience are extremely non-linear, partly because the tank is a weird shape to fit in the space allowed, but also because the manufacturer won't take the time to really calibrate it.
So I also track where the fuel gauge indicates and reference that as I plot the data when I fill up at different indicated levels. Call me obsessive. After that only a glance at the gauge and I know for real what I have, without calculations.
