Why doesn't F1 refuel during races?

The ban

Refuelling during a race was outlawed from the 2010 season and has stayed banned since^[1]. The FIA's stated reasons were safety and cost: refuelling rigs had caused pit-lane fires and dangerous moments with hoses, and shipping the heavy equipment to every race added expense the sport sought to cut^[1].

What changed on the car

To run a full race on a single fill, the rules let the cars grow to fit a much larger fuel tank from 2010 onward^[2]. Every car now starts heavy, with all its fuel on board, and gets lighter and faster as that fuel burns off through the race^[2].

How it shaped strategy

• Fuel is no longer added at stops, so a pit stop is purely about changing tyres (and any penalties served).
• Drivers manage fuel to reach the finish, using techniques like lift and coast when they are running short.
• Starting weight is fixed by the fuel load, so the early laps are run on the heaviest the car will be all day.

The strategic upside the ban removed

:::analysis Refuelling-era strategy was partly a fuel game: a team could run a car light and fast on a short fuel load, then make up the stop time, which created strategic variety but also meant much of the "racing" happened in the pit cycle rather than on track. Banning refuelling pushed the strategic battle back onto tyres and track position, which is where it largely sits today. It also rewards efficiency, since a team that burns less fuel can carry less of it and run lighter, a thread that runs straight into the 2026 rules, where energy and fuel management are even more central.
