F1 fuel load and fuel saving explained
How starting fuel affects mass, lap time and the need to manage consumption.

Quick answer
More starting fuel adds mass and slows the car, while too little risks failing to finish or supply the required sample. Teams model consumption and drivers save with lift-and-coast and engine settings.
Choosing the start load
Teams estimate racing laps, formation procedures, weather, neutralisations and likely pace. Carrying unnecessary fuel costs time on every early lap.
How drivers save
Lifting before braking, short-shifting and adjusting deployment can reduce consumption. The fastest technique depends on where it gives up the least lap time.
Safety Cars change the model
Neutralised laps usually consume less fuel, creating margin. A race with no interruptions may require more deliberate saving than teams expected.
