Sorry for yet another novice question but I'm a quick study. I notice that, no matter how much fuel I put in the car, the fuel/distance guage readout in the cockpit HUD reads "n/a". And I do not seem to run out; when loading 2.5 gallons for quals at Interlagos, I'm pretty sure I ran at least 5 laps with no fuel low warning. I am running all "realism"-type options at the highest settings so I'm a bit baffled by what seems to be automated fuel loading. As usual, I might be missing something simple but I do not see any option for fuel load/calculation (apart from the metric/imperial choice) and I need to figure out fuel loads for a race, i.e. 40 laps in the F3 at Interlagos. Can anyone help? Many thanks.
