What You'll Learn
The Cessna 172S has a total fuel capacity of 56 gallons
The Cessna 172 is a four-seat, single-engine piston aircraft with a high fixed wing. It was first flown in 1955 and has been in the air for nearly seven decades. The Cessna 172S, introduced in 1998, has a total fuel capacity of 56 gallons, with 28 gallons in each of its two fuel tanks. However, only 53 gallons of fuel are usable, as the remaining fuel may be contaminated by dirt or other contaminants, which settle at the bottom of the fuel tanks.
The Cessna 172 has played a significant role in aviation history and is the most successful aircraft in history, with over 44,000 built to date. Its enduring popularity and reliability have made it a favourite among pilots. The aircraft is certified for instrument flight and is used for both travel and training. In fact, more than 50% of the world's pilots started their training in the Cessna 172.
The Cessna 172 has undergone several modifications over the years, including increased engine power, higher gross weights, and additional fuel tank capacity. For example, the 1969 model offered optional long-range 52-US-gallon wing fuel tanks. The 1976 Cessna 172M with standard tanks has a total fuel capacity of 42 gallons, while the long-range tank option offers a capacity of 52 gallons.
The price of a Cessna 172 can vary depending on factors such as age, flight time, modifications, and maintenance. As of early 2024, the average price for a used Cessna 172 is around $100,000, while a new one costs approximately $400,000.

Each of its two tanks can hold 28 gallons
The Cessna 172 is a single-engine piston aircraft with a high fixed wing. It has proven to be a popular aircraft for flight training and personal use, with more than 50% of the world's pilots starting their training in the Cessna 172. The Cessna 172 has two fuel tanks, with each tank mounted in each wing. Each of its two tanks can hold 28 gallons, for a total fuel capacity of 56 gallons. However, only 53 gallons of fuel is usable. This is because the lines that draw fuel to the engine are slightly above the bottom of the tanks, preventing fuel contamination.
The Cessna 172 has played a significant role in aviation history. It was first flown in 1955 and has remained popular for nearly seven decades. The Cessna Aircraft Company, now known as the Textron Aviation Company, built the first production models of the Cessna 172 in 1956. The aircraft was named the Skyhawk and quickly became popular as it was used in most pilot training facilities across the United States.
The Cessna 172 has undergone several modifications and variants over the years, including increased engine power, higher gross weights, and additional fuel tank capacity in the wingtips. The popularity of the Cessna 172 led to its enduring presence in the aviation world, with Cessna producing more than 44,000 Cessna 172 aircraft as of 2024.
The price of a Cessna 172 can vary depending on factors such as age, flight time, modifications, and maintenance. As of early 2024, the average price for a used Cessna 172 is around $100,000, while a new one costs around $400,000.

The 1976 Cessna 172M has a fuel capacity of 42 gallons
The Cessna 172 is a single-engine piston aircraft with a high fixed wing. It was first flown in 1955 and played a significant role in aviation history. The Cessna Aircraft Company, now known as the Textron Aviation Company, built the first production models in 1956. The aircraft was named the Skyhawk and became popular for pilot training. It is known for its endurance and has been used by more than 50% of the world's pilots to start their training. Cessna has produced more than 44,000 Cessna 172 aircraft, making it the most successful aircraft in history.
The Cessna 172 has two fuel tanks, with one tank mounted in each wing. The 172's fuel selector valve can be placed in a "both" position, allowing fuel to flow from both tanks simultaneously. This is a unique feature compared to most low-wing aircraft, which only have "Left" and "Right" settings.
The Cessna 172's fuel system includes an electric fuel pump, which serves as a backup in case the engine-driven pump fails. The system also includes a fuel injector servo regulator, which creates the right ratio of air-to-fuel by comparing inlet air pressure to fuel inlet pressure. This allows for a metered fuel pressure, which adjusts as the throttle increases and airflow through the engine drops pressure in the venturi.
The Cessna 172's fuel tanks have supply lines with mesh screens to eliminate sediment. There is also a finer filter and sump, sometimes called a "gascolator," which can be drained to check for contaminants.

The 172N has a capacity of 43 gallons
The Cessna 172 is a four-seat, single-engine piston aircraft with a high fixed wing. It was first flown in 1955 and has been in the air for nearly seven decades. The Cessna 172N is a variant of this model, introduced in the late 1970s.
The Cessna 172 has two fuel tanks, with one tank mounted in each wing. The aircraft's endurance and popularity have made it the most successful aircraft in history, with over 44,000 Cessna 172s built to date. The 172N's increased fuel capacity further contributes to its endurance, allowing for longer flights and extended range.
The Cessna 172's fuel system is designed to maintain a constant fuel flow and ensure proper fuel-air ratios in each cylinder. The electric fuel pump provides redundancy in case of engine-driven pump failure, ensuring the engine continues to receive adequate fuel pressure. The fuel supply lines also have a mesh screen and finer filters to eliminate sediment and contaminants from the fuel system.

Additional fuel tank capacity can be added in the wing tips
The Cessna 172 is a four-place aircraft certified for instrument flight. It is a popular aircraft for travel and training. The Cessna 172 may be modified in a wide array of ways, including increasing its engine power, gross weight, and fuel tank capacity.
Additional fuel tank capacity can be added to the Cessna 172 in the wing tips. This modification can increase the aircraft's range and endurance. The wing tips can carry 24 gallons of fuel in total, with 23 gallons being usable. The tanks are made of fiberglass and fit inside the outermost two bays of the wing. The installation process involves removing the close-out rib and cutting a hole in the second rib for the tank to slide through. This modification does not compromise the strength of the wing, as the tank has a built-in rib.
The fuel line is then run inboard to the main tank, with the transfer pump and check valves mounted near the strut attachment point. For rubber cell mains, the fuel enters through a tee fitting in the door post. Aircraft with bladder main tanks may require additional installation time. For metal main tanks or wet wings, a bulkhead fitting is installed in the side or top of the main tank.
The addition of tip tanks is a popular option for increasing the fuel capacity of the Cessna 172. This modification can provide increased range and endurance, making it a suitable option for those seeking longer flights or improved fuel efficiency.

Frequently asked questions
The fuel capacity of a Cessna 172 varies depending on the model. The 1976 Cessna 172M ordered with standard tanks has a capacity of 42 gallons, while the long-range tanks option can hold 52 gallons. The 172N model has a capacity of 43 gallons. The Cessna 172S has a total fuel capacity of 56 gallons, with 28 gallons in each of its two tanks.
For the 1976 Cessna 172M with standard tanks, 38 gallons of fuel is usable. The long-range option provides 48 usable gallons. The 172N model has 40 gallons of usable fuel. While the Cessna 172S has a total fuel capacity of 56 gallons, only 53 gallons are usable. This is because the fuel at the bottom of the tanks may become contaminated with dirt or other contaminants, so the lines that draw fuel to the engine are positioned slightly above the bottom to avoid drawing contaminated fuel.
The model introduced in 2014 burns 3 US gallons (11 L; 2.5 imp gal) per hour less fuel than the standard 172.
