The Boeing 767 is a popular aircraft for commercial aviation, widely used for both domestic and international routes, as well as cargo transport. Its fuel efficiency, adaptability, and long-range capabilities have made it a pillar of overseas routes and intercontinental services. The 767's fuel economy is due in part to its twin-engine configuration, which reduces operational costs for airlines compared to older, four-engine aircraft. The 767-300ER variant, for example, can carry up to 24,140 gallons of fuel and achieve a range of over 6,600 nautical miles. The type of fuel used in the Boeing 767 is standard aviation jet fuel, similar to kerosene, and referred to as Jet A or Jet A-1.

Fuel capacity: 20,112 gallons
The Boeing 767 is a versatile and successful aircraft in commercial aviation. It is a wide-body, twin-engine jetliner that has been widely adopted by airlines worldwide since its introduction in 1981/1982. The 767 is known for its efficiency, reliability, and long-range capabilities, making it suitable for both passenger and cargo operations.
The fuel capacity of the Boeing 767-300 is 20,112 imperial gallons (91,380 litres or 73,078 kg). This specific variant of the aircraft is powered by RB211-524H engines, which burn standard aviation jet fuel. This fuel is similar to kerosene and is known as Jet A or Jet A-1. It is a highly refined and purified clear to straw-coloured liquid, specifically blended to power turbine engines at high temperatures and pressures during jet flight.
The Boeing 767's fuel efficiency contributes to its long-range capabilities. Depending on the model, the aircraft can achieve a range of up to 6,385 nautical miles. With lower fuel loads, the typical range is between 3,000 and 4,000 nautical miles for transcontinental flights.
The 767-300ER variant has an even higher fuel capacity of 24,140 gallons, allowing it to achieve a range of over 6,600 nautical miles. This flexibility in fuel load and range has made the Boeing 767 a popular choice for overseas routes and intercontinental services.

Fuel consumption: 1,199 gallons per hour for short-haul flights
The Boeing 767 is a popular aircraft for commercial aviation that has been in use since 1981/1982. It is a wide-body, twin-engine jetliner known for its versatility, efficiency, reliability, and long-range capabilities.
The 767 is powered by high-bypass turbofan engines, most commonly the Pratt & Whitney or General Electric engines, which burn standard aviation jet fuel. This jet fuel is similar to kerosene and is referred to as Jet A or Jet A-1, which is a highly refined and purified clear to straw-coloured liquid.
The fuel consumption of the 767 depends on the variant and the length of the flight. For short-haul flights, the 767-300 variant with RB211-524H engines consumes 1,199 imperial gallons (5,451 litres or 4,360 kg) of fuel per hour. This fuel consumption rate is specific to this variant and may vary slightly for other versions of the 767.
The 767's fuel efficiency, along with its range of configurations, has made it a popular choice for airlines worldwide. Its twin-engine configuration contributes to its fuel efficiency, making it more economical than older, four-engine aircraft. This reduced fuel consumption leads to lower operational costs for airlines.

Jet fuel: similar to kerosene
The Boeing 767-300's fuel consumption is 1,199 imperial gallons (5,451 litres/4,360 kg) per hour for short-haul flights and 1,279 imperial gallons (5,813 litres/4,650 kg) per hour for long-haul or regional flights. The total fuel capacity of the 767-300 is 20,112 imperial gallons (91,380 litres/73,078 kg).
Jet fuel, which is used to power aircraft like the Boeing 767, is similar to kerosene. It is a gas turbine fuel used in propeller and jet fixed-wing aircraft and helicopters. Jet fuel is derived from petroleum or is a blend of petroleum and synthetic fuels. Most jet fuels are kerosene-based, such as JP-8 and Jet A-1, which are used in gas turbine-powered aircraft. Jet A-1 is an unleaded kerosene, while Jet B is a naphtha-kerosene blend with a very low freezing point of -76°C, making it useful in cold areas.
Kerosene-based jet fuel has a much higher flash point than gasoline-based fuel, meaning it requires a significantly higher temperature to ignite. It burns at temperatures of 49°C or above. Jet fuel has a low viscosity at low temperatures, limited ranges of density and calorific value, burns cleanly, and remains chemically stable when heated to high temperatures.
The energy content of jet fuel depends on its composition. For example, the net energy content of BP Jet A-1 kerosene is 43.15 MJ/kg, with a density of 804 kg/m3 (34.69 MJ/litre) at 15°C. In comparison, the density of jet fuel used in airliner performance calculations is around 0.80 kg/L (6.7 lb/US gal; 8 lb/imp gal).

Engines: Pratt & Whitney or General Electric
The engines that power the Boeing 767 depend on the generation of the aircraft. The first 767-200s and 767-300s were powered by the Pratt & Whitney JT9D turbofan engine. This was the manufacturer's first high-bypass-ratio turbofan engine. The JT9D was later developed into the PW4000, which became the 767-400ER's exclusive powerplant. The PW4000 engine series proved to be the perfect powerplant for the 767, offering exceptional fuel efficiency, lower operating costs, and increased thrust. The -94 variant used in the 767 produces 50,000-62,000 pounds of thrust.
The next generation of the Boeing 767 used the General Electric CF6 engine, which was launched in 1986. These engines were used in the 767-200ER and 767-300ER models. The CF6 engine had higher bypass ratios and used next-generation materials, producing between 52,500 and 62,100 pounds of thrust. The CF6 engine has also been used in other aircraft, such as the Airbus A300 and A310, and the Boeing 747-400.
Another engine used in the Boeing 767 is the Rolls-Royce RB211, which was delivered to British Airways in 1990. More powerful variants of the PW4000 and RB211 engines later became available for the 767-300 and its extended-range version, the 767-300ER.
