Just had to exit a 30 minute P3 race at Bathurst due to running out of fuel. Lap times were just under 2:10, so 130 seconds. Race time is 30 x 60 = 1800 seconds. Therefore expected laps should be 13.8. I calculated this pre-race and fueled for 15 laps according to the UI but ran out on lap 7, about half way through what was expected. It was a cracking race too between me and the next guy, such a shame. This has happened a few times before, especially at Bathurst in various cars. Do other people experience this and what are work arounds? I figure I can use a 3rd party app to see the actual fuel usage per lap and disregard the in game prediction.
