The T-6 Texan, also known as the Harvard, is a military aircraft with a fuel burn of 32 gallons per hour at normal cruise. The fuel burn depends on the power setting and the engine itself, and can be anywhere from 80-120 litres per hour. The T-6's standard tanks hold 110 gallons of fuel and last for a little under three hours plus reserve. The aircraft's oil consumption rate can vary depending on the condition of the engine, with some reporting consumption rates of 4-5 quarts per hour.

What You'll Learn
Fuel burn rate depends on power settings and the engine
The fuel burn rate of a T-6 aircraft depends on the power settings and the engine. The fuel burn rate can vary from 80 to 120 litres per hour, depending on the engine and its condition. For example, the R-1340 engine used in the T-6 has been reported to consume between 4 and 5 quarts of oil per hour, which was reduced to less than a quart per hour after an engine overhaul.
The T-6 typically runs on Avgas, which can be expensive and difficult to obtain. Avgas prices can range from US$2.50 to US$4 per litre. However, it is possible to operate the T-6 on a blend of 75% mogas and 25% Avgas, which can be more cost-effective.
At normal cruise power settings, the T-6's fuel burn rate is approximately 32 gallons per hour, which is substantial but only half the rate of a P-51 aircraft. At current fuel prices, this equates to approximately US$150 per hour. If the aircraft is used for acrobatic manoeuvres, the fuel burn rate and cost can increase to approximately US$200 per hour.
The T-6 has a standard fuel tank capacity of 110 gallons, which provides a flight endurance of slightly less than three hours, including reserve fuel. The cruise speed of the T-6 is typically around 140 knots, and the aircraft's stall characteristics are manageable with proper training and awareness of its peculiarities.

Avgas is expensive, running between $2.50 and $4 per litre
Avgas is a fuel used in aircraft, and its price per litre varies. The cost of Avgas is relatively high compared to other types of fuel, with prices ranging from $2.50 to $4 per litre. This price variation can be influenced by various factors, including location, supply and demand dynamics, and taxation.
The high cost of Avgas can have significant implications for aircraft owners and operators, especially those who regularly fly or own fuel-inefficient models. For example, the T-6 Texan, a well-known aircraft, has been challenged to fly due to the difficulty and expense of obtaining Avgas. The T-6 consumes approximately 80-120 litres of fuel per hour, depending on factors such as power settings and engine specifications. At a fuel burn rate of 32 gallons per hour during normal cruise conditions, the hourly fuel expense for a T-6 can reach approximately $150.
With Avgas prices at the higher end of the range, the financial burden becomes more substantial. For instance, if Avgas is priced at $4 per litre, and the T-6 consumes 120 litres per hour, the hourly fuel cost would amount to $480. This substantial expense can significantly impact the operating costs of the aircraft, influencing decisions regarding flight frequency, duration, and overall affordability.
To manage the high cost of Avgas, some aircraft owners and operators explore alternative fuel options or blends that can be used in certain aircraft types. For example, a blend of 75% mogas and 25% Avgas has been suggested as a more cost-effective solution for the T-6, potentially reducing fuel expenses. However, it is important to consider the compatibility and performance implications of using different fuel blends, as they may vary across different aircraft models.
While Avgas is expensive, it is crucial to acknowledge that aircraft fuel costs are just one aspect of the overall expenses associated with aviation. Maintenance, storage, insurance, and various operational fees also contribute to the financial commitments required to own and operate an aircraft. Therefore, while the high price of Avgas can be a significant factor, it is just one piece of the broader financial puzzle in the world of aviation.

Standard tanks last for a little under three hours
The T-6 is a military aircraft that has been praised for its agility and awarded in various air shows. Its fuel consumption depends on the power setting and the engine itself, which can be anywhere from 80-120 litres per hour. The standard tanks on a T-6 hold 110 gallons of fuel, which last for a little under three hours. This means that the fuel burn rate of the T-6 is approximately 32-37 gallons per hour.
The T-6's fuel consumption is also impacted by the type of fuel used. Avgas, for instance, can cost up to US$4 per litre. A more cost-effective alternative is to use a blend of 75% mogas and 25% avgas, which some T-6 operators have successfully utilised. Mogas is significantly cheaper, costing only US$1 per litre.
The T-6's fuel efficiency is further influenced by the specific model and its engine type. For example, the R-1340 engine is known for its high oil consumption, which can be as much as 4-5 quarts per hour. However, with proper engine maintenance, this can be reduced to less than a quart per hour.
Overall, the T-6's standard fuel tanks provide enough fuel for a typical flight duration, and operators can optimise fuel efficiency by considering fuel types and addressing high oil consumption through engine maintenance.

Oil consumption varies depending on the condition of the engine
In the context of the T-6 aircraft, fuel burn depends on the power setting and the engine itself. Estimates for fuel consumption range from 32 gallons per hour at normal cruise to 80-120 liters per hour. The cost of fuel for a T-6 at cruise conditions is approximately $150 per hour, and performing acrobatics can increase this to $200 per hour.
To manage oil consumption, it is important to use the factory-recommended oil and monitor oil levels between scheduled changes. If oil consumption is high, it may indicate an underlying problem with the engine or another component. Leaking gaskets, for instance, often need to be replaced. In the case of a turbocharger, a wobbling shaft can cause oil to leak into the intake manifold and combustion chambers, resulting in blue smoke. Therefore, it is crucial to address any signs of malfunction or damage promptly.
Additionally, understanding oil transport mechanisms is essential to prevent oil from reaching areas where it can cause damage. Oil consumption primarily occurs near or through the combustion chamber, either downward through valves or upward past the piston ring-pack. By comprehending these mechanisms, we can better address issues that contribute to excessive oil consumption and engine wear.

Fuel burn rate at normal cruise is about 32 gallons per hour
The fuel burn rate of a T-6 aircraft at normal cruise is approximately 32 gallons per hour. This rate of fuel consumption is dependent on the power setting and the specific engine of the aircraft. For instance, the R-1340 engine can burn anywhere from 80 to 120 litres per hour, with some variations depending on the engine's condition and the flight length.
The T-6 is a versatile aircraft capable of cruising at speeds of about 140 knots. Its standard tanks, with a capacity of 110 gallons, can last for nearly three hours, including reserve fuel. This duration can be influenced by factors such as stall characteristics, proper checkout procedures, altitude, and understanding the aircraft's unique traits.
The T-6 has a reputation for being a capable trainer aircraft, preparing pilots for a range of military airplanes. Its cockpit is notably spacious, comfortably accommodating pilots of various heights.
The expense of operating the T-6, particularly the cost of avgas, can be a significant consideration. Avgas prices can range from US$2.50 to US$4 per litre, impacting the overall fuel expenses for the T-6, which can reach approximately $150 per hour at cruise speeds.
