F1 fuel regulations
Formula One (F1) cars can carry up to 110 kg of fuel per race. However, teams often under-fuel their cars to achieve faster lap times and improve tyre life. This is because the more fuel a car starts with, the heavier it is, and the more lap time it loses. The average F1 car gets approximately 6.2 miles per gallon.
F1 regulations have pushed towards fuel efficiency in recent years. F1 engines can achieve more than 50% thermal efficiency, largely thanks to the MGU-H, a generator-like device attached to the turbocharger shaft that transforms waste heat into rotational energy to recharge the battery. This battery then powers the crankshaft-mounted MGU-K electric motor/generator.
F1 engines run on petrol, though the regulations are designed to ensure the fuel used is not entirely dissimilar to that used in road cars. It must be formulated from compounds found in commercial fuels and has strict regulations on impurities. Teams are limited to five types of fuel during the season, and a maximum of two formulations can be used at each event.
In 2010, refuelling during the race was banned, and cars are now fuelled to complete the race distance. F1 fuel bladders must be a single rubber bladder that conforms to strict safety rules. The fuel bladder is located near the centre-line of the car and behind the cockpit.
F1's governing body, the FIA, has unveiled regulations for 2026 and beyond that focus on agility, competitiveness, safety, and sustainability. F1 aims to achieve net-zero emissions by 2030, with plans to use 100% sustainable fuel and synthetic e-fuels made from water and carbon dioxide.

Fuel consumption
In the past, high fuel consumption was often seen as desirable, indicating that a car was being driven to its limits. However, with increasing concerns about environmental impact and sustainability, the perception has shifted towards efficiency and clean energy. This change in perspective has influenced the world of motorsport, with Formula One organisations aiming for net-zero emissions by 2030.
The fuel consumption of Formula One cars is heavily regulated, with rules in place to ensure sustainability and fair competition. Since 2014, F1 cars have been required to have fuel-flow meters to monitor fuel consumption, ensuring it does not exceed 100kg per hour. The fuel used in these cars is also strictly regulated, with the International Automobile Federation (FIA) overseeing the specifications and composition. It is composed of compounds found in commercial fuels and must adhere to strict standards, such as the Euro 95 standard, which ensures it contains the same compounds as the fuel used in road cars.
The amount of fuel a Formula One car can use per race has varied over the years. In 2019, the limit was increased to 110 kilograms to allow drivers to push harder, but this does not mean they always fill up to capacity. Teams must consider the trade-off between fuel load and car weight, as a heavier car can result in higher lap times. Short-fuelling strategies are often employed, where 5-15kg less fuel is used to benefit from a lighter car, accepting the need for strategic lift-and-coast techniques later in the race.
Formula One engines have also become more fuel-efficient over time, with advancements in technology. For example, the 2020 Mercedes engine achieved over 50% thermal efficiency, an increase from around 44% in 2014. This means that more than half of the energy in the fuel is used to propel the car forward, compared to approximately 30% in standard road cars. The use of hybrid technology, such as the MGU-H and MGU-K systems, has also contributed to improved fuel efficiency and reduced carbon emissions.
The push for sustainability has led to innovations in fuel type as well. Formula One currently uses E10 fuel, which contains 10% renewable ethanol, but there are plans to transition to 100% sustainable fuel by 2026. This future fuel will be derived from non-food biomass, municipal waste, and renewable sources, marking a significant step towards reducing the carbon footprint of the sport.

Fuel efficiency
F1 engines use turbocharged 1.6-liter V6 hybrid powertrains, producing 1,000 horsepower while running on 87-octane E10 fuel, a blend of 90% gas and 10% ethanol. The use of ethanol contributes to the push for sustainability in the sport, with F1 aiming to achieve net-zero emissions by 2030. The hybrid setup not only increases efficiency but also allows for the recovery of waste energy. The Energy Recovery Systems (ERS) in F1 cars ensure that waste energy is captured and reused, with the MGU-H collecting wasted energy from the turbocharger and the MGU-K recovering waste kinetic energy from the braking system.
The aerodynamics of the cars also play a role in fuel efficiency. While the current generation of cars produces more downforce, the resulting drag has increased fuel consumption. To mitigate this, drivers employ fuel-saving techniques such as lift-and-coast, where they lift off the throttle before the braking zone when entering corners. Additionally, adjustments to the car's settings can help decrease fuel consumption, although this may impact the car's performance.
F1 regulations have also contributed to the push for fuel efficiency. Since 2014, F1 cars have been required to have fuel-flow meters to ensure that the engine's fuel consumption does not exceed 100kg per hour. The FIA, the governing body, introduced a second fuel-flow sensor in 2020 to better enforce the rules surrounding fuel usage, with encrypted data to prevent tampering.
The fuel used in F1 is also highly regulated to ensure it is similar to commercial fuels while optimising performance. The fuel blends are tailored to each team's engine characteristics, with designated fuel suppliers creating specific formulations. These fuels are constantly being improved to deliver more power and better economy, with ExxonMobil working closely with Honda to test new blends.
Overall, the focus on fuel efficiency in Formula One racing has led to significant advancements, with the sport aiming to create more sustainable fuels and reduce its environmental impact while also improving performance.

Fuel loads
F1 cars are allowed a maximum fuel load of 110 kilograms per race, which was increased from 105 kilograms in 2019. However, it's important to note that cars don't always start a race with a full fuel load, as a heavier car results in slower lap times. Teams must strategically decide how much fuel to load, considering factors such as race distance, engine efficiency, and fuel consumption rates.
The fuel load can vary depending on the circuit and race strategy. For example, at circuits with longer straight sections, cars may require more fuel to maintain higher speeds. Additionally, teams may opt for a short-fuel strategy, carrying 5-15 kilograms less fuel to benefit from a lighter car and improved tyre life, accepting the need for strategic lift-and-coast later in the race.
The weight distribution of the fuel load is also crucial. F1 regulations require the fuel to be stored in a fuel sack or bladder mounted close to the centre line of the car and as low to the floor as possible. This distribution affects the car's centre of gravity and overall balance, influencing its handling and performance.
In recent years, there has been a push towards lower fuel loads in F1. The focus on fuel efficiency and sustainability has driven this trend, with the sport aiming for net-zero carbon emissions by 2030. The thermal efficiency of F1 engines has improved significantly, with advancements in technology, such as the MGU-H and MGU-K systems, allowing engines to achieve over 50% thermal efficiency. As a result, fuel loads have decreased from 160 kilograms in 2013 to 100 kilograms in 2020, with a further reduction to 70 kilograms expected by 2026.

Fuel types
Although I could not find specific information about the fuel types used in Reno Formula One aircraft, I did find some general information about fuel types used in Formula One aircraft and cars.
Formula One engines run on petrol, or, in the words of the technical regulations, "petrol as this term is generally understood". The regulations are designed to ensure that the fuel used in Formula One is not entirely dissimilar to that used in road cars. It must be formulated from compounds found in commercial fuels, and it is subject to very strict regulation of impurities. The fuel cannot contain exotic power-boosting chemical compounds.
Formula One fuel has to be optimised for the specific engine it will be used with. When the engine supplier alters the specification, even slightly, the fuel has to be adjusted to maximise performance. While teams are only allowed five types of fuel during the season, companies like ExxonMobil will be constantly sending new formulations for testing. Before a new fuel can be used, two separate 5-litre samples must be submitted to the FIA for analysis and approval.
Formula One cars use a maximum of 110 kilograms of fuel per race (305km / 190 miles). However, they don't always fill the car with that much fuel because the more fuel a car starts with, the heavier it is, and the more lap time it costs. The average Formula One car gets approximately 6.2 miles per gallon.
There has been a push towards fuel efficiency in recent years, with Formula One regulations aiming for net-zero emissions by 2030. Formula One is also planning on using synthetic e-fuels made of water and carbon dioxide, without any fossil sources.
