I should clarify that when running the Porsche for an hour at 3x fuel on Le Grand Circuit, I had to make one pitstop after just over half an hour, and then took on 100l of fuel to make it to the end. So the tank would last at least 90 minutes on normal fuel settings. I communicated that poorly on Discord. Wear was below 3% after the full hour on the default tyres. I just gave the Austin a go at Le Grand Circuit and it was difficult to get used to after trying the mid to high pack cars. It felt a lot more oversteery and quite a challenge!
