Re this Mark Webber misfortune, all teams use the absolute minimum weight of fuel to do the time on track at hand, BUT this Webber affair was not a fuel miscalculation, it was a malfunction of the fuel rig, the RB8 did not stop out on track because it ran out of fuel, Webber was told to stop the car because of fuel shortage to prevent damage to the main fuel pressure pump and possibly the engine. The two or three fuel transfer pumps inside the tank are capable of running dry without damage to themselves but the main pressure pump (max 100 bar) will be damaged if run dry, also the engine (pistons/valves) can be damaged by a suddenly lean injected fuel when an engine is running out of fuel, as the amount of fuel injected plays an important part in the cooling of pistons and valves.
