In endurance motorsport the amount of fuel a car carries directly influences lap times, handling balance, and overall race strategy. Teams start by estimating the total distance of the event and the car’s average fuel consumption, which is usually expressed in litres per 100 kilometres (L/100 km).
The core calculation converts distance and consumption into a raw fuel requirement. This is then adjusted with a safety margin to protect against unexpected higher consumption or safety‑car periods.
Once the total fuel is known, the team compares it to the car’s tank capacity to decide how many pit stops are required. Each pit stop adds a fixed time penalty, so the optimal plan balances fewer stops against the risk of running low on fuel.
