The Cessna 172 is a single-engine propeller-driven aircraft that has been on the market since 1956 and is one of the most widely used training aircraft. With a seating capacity of up to four people, including the pilot, the Cessna 172 is a versatile and spacious option for personal and business use. When it comes to fuel consumption, the Cessna 172 typically burns around 7 to 9 gallons of fuel per hour, depending on various factors such as speed and weight. This equates to approximately 15 miles per gallon, which is lower fuel efficiency than most road cars. However, it's important to note that fuel efficiency is not the only factor to consider when comparing the operating costs of a Cessna 172 to that of a car.
| Characteristics | Values |

What You'll Learn

The Cessna 172 burns 7-9 gallons per hour
The Cessna 172 is a single-engine propeller aircraft with a high wing design, offering seating for up to four people, including the pilot. It is renowned for its excellent safety record, stability, and superior downward visibility due to its high-decker wing placement.
The Cessna 172's fuel consumption is approximately 7-9 gallons per hour. This rate of fuel burn is influenced by various factors, including speed and wind conditions. For instance, without wind, the Cessna 172 consumes about 13 litres per 100 kilometres, translating to a fuel efficiency of approximately 15 miles per gallon. At a cruising speed of 125 mph, the aircraft burns about 8 gallons per hour.
The hourly fuel costs for the Cessna 172 can range from $42 to $54 per hour, considering that Avgas typically costs around $6 per gallon. However, it's important to note that fuel prices can vary across different airports. Additionally, the overall operating costs of the aircraft include maintenance expenses, which can be roughly $50 to $60 per hour of flight time.
To optimise fuel efficiency, pilots should pay attention to the Performance Chart, taking into account factors such as power percentage, altitude, and rpm settings. By understanding these variables, pilots can make informed decisions about fuel loading and reserve amounts, thus avoiding fuel mismanagement accidents, which are common in general aviation.
In summary, the Cessna 172's fuel consumption of 7-9 gallons per hour, coupled with its spacious interior and excellent safety record, makes it a versatile and popular choice for both personal and business aviation needs.

Avgas costs around $6 per gallon
The Cessna 172 is a light, single-engine propeller aircraft that burns approximately 8 gallons of fuel per hour when cruising at 125 mph. This works out to around 15 miles per gallon (MPG), which is less efficient than most road cars.
The high fuel consumption and associated costs of the Cessna 172 may be surprising, especially when compared to the fuel efficiency of a car. However, it is important to note that the benefits of flying an aircraft like the Cessna 172 go beyond just the fuel efficiency. For longer distances, flying can be a significant time saver, and the convenience and speed of air travel can often outweigh the higher fuel costs.
Additionally, the type of fuel and prices can vary. The national average price for jet fuel in the US as of July 22, 2025, was $6.29 per gallon, while the national average price for 100LL aircraft fuel was $6.52 per gallon. Prices can also vary by region, with the FAA Alaska region reporting the highest jet fuel price at $8.09, and the FAA Central region reporting the lowest price at $5.59.
While the hourly fuel consumption and costs of a Cessna 172 are important considerations, they are just one aspect of the overall ownership or rental expenses. It is crucial to take into account other factors, such as maintenance, insurance, and hangar or storage fees, to get a comprehensive understanding of the total cost of operating this aircraft.
