Fuel Strategy Calculator

This calculator works backward from your tank capacity and per-lap fuel burn to build a full-race pit strategy. It first divides tank capacity by fuel consumption per lap to get a theoretical laps-per-tank figure, then subtracts a half-lap reserve and rounds down, so you're never assumed to run a tank dry with no margin for a slow lap or a late caution. Dividing total race laps by that safe laps-per-stint figure (rounded up) gives the number of stints needed, and the number of pit stops is simply one fewer than the number of stints, since the final stint doesn't require another stop. Total pit time is just stops multiplied by your entered time-per-stop, which should already include pit lane speed limit zones, not just the stationary fueling time.

Fuel per stint is capped at whatever the tank can actually hold, so it won't suggest loading more fuel than fits even if a stint is short. The estimated total race time is a simple sum of every lap at your average pace plus all accumulated pit time — it does not account for out-lap or in-lap time loss beyond what you've already built into pitStopTime, nor does it model fuel-saving pace adjustments some strategies use to stretch a stint by an extra lap or two. The fuel-level chart traces a simple sawtooth across the race, dropping each lap and resetting to full at every simulated pit stop, giving a quick visual sanity check on when stops will actually fall.
