Just to clarify: I (almost) never run with more fuel than I need to complete a race (with reasonable safety margin), as I'm (almost) always faster in a lighter car. It's the endurance and long distance races where I know I will need to refuel, that I always start with a full tank. Whatever is there from the start, is there 'for free' - if I have to add it later during a pit stop, it will cost time - most likely more time than I save by omitting it from the start.
With regards to sliding around on worn tyres; even if it's to your liking (Clive
), it's a bit of a double edged sword, as the sliding will drastically increase the wear, and so has to be included in the considerations about how to drive and whether to change tyres or not. (It's very evident in this Cup, with 2x tyre wear - as soon as you're sliding, wear values as seen on XD are spooling up)
