What You'll Learn
The Abrams tank's fuel economy
The M1 Abrams tank is a powerful vehicle with a gas turbine engine designed to burn jet fuel. While it can technically run on a variety of fuels, including diesel, jet fuel, kerosene, gasoline, and even questionable heating oil, its fuel economy is notoriously poor.
The Abrams tank is estimated to consume between 1.5 to 3 gallons of fuel per mile, which is an incredibly high fuel consumption rate, even when compared to other tanks. This means that the Abrams requires a constant and substantial supply of fuel to keep it running, which can be a significant logistical challenge, especially in a conflict zone like Ukraine, where the US has supplied a number of these tanks.
The poor fuel economy of the Abrams tank has been a well-known issue for some time. As far back as 1990, a report by the Project on Government Oversight criticized the M1 Abrams for its high costs and low fuel efficiency compared to other similar tanks, such as the German-made Leopard 2. The report found that the M1 Abrams burned 83% more fuel than the Leopard 2 at the same speed.
Despite its fuel-guzzling reputation, the Abrams tank is still highly regarded for its speed, firepower, and armor. However, the fuel consumption does present a significant challenge, requiring a large logistics operation to ensure a continuous supply of fuel, which can be difficult to achieve, especially in areas with limited fuel resources or challenging terrain.

The jet fuel requirement
The M1 Abrams tank is powered by a gas-turbine engine, which runs on jet fuel. This is a specific type of fuel, also known as JP-8 aviation fuel, that presents logistical challenges for the Ukrainian military, which would need a steady supply delivered to the front line. The tank's fuel economy is poor, even compared to other tanks, and it consumes an estimated 1.5 to 3 gallons per mile. This means that the tank requires an enormous logistics chain to supply it with fuel continuously.
The Abrams tank's engine gulps fuel voraciously, and its fuel consumption is a major consideration for users. The tank is very heavy, and its fuel capacity and range limitations led to the adoption of a jet engine. The jet engine allows the tank to manage its fuel capacity and range, but it still consumes a large amount of fuel.
The M1 Abrams tank can run on a variety of fuels, including diesel, jet fuel (Jet A, Jet B, JP4, JP5, JP8), kerosene, home heating oil, and gasoline. However, jet fuel is the standard fuel for the tank, and it is what the tank was designed to run on. While the tank can technically run on diesel, this requires the addition of a special additive due to jet fuel's lack of lubricating properties.
The use of jet fuel in the M1 Abrams tank is a potential issue for the Ukrainian military, as it may be difficult to secure a steady supply of this specific type of fuel on the front lines. However, some have expressed confidence that Ukraine will be able to overcome this hurdle with the support of its allies.

The tank's fuel capacity
The M1 Abrams tank is a powerful vehicle with a gas turbine engine that can run on a variety of fuels, including diesel, jet fuel (Jet A, Jet B, JP4, JP5, JP8), kerosene, home heating oil, and gasoline. However, its fuel efficiency is a notable concern, with estimates placing its consumption at between 1.5 to 3 gallons per mile. This measurement highlights its deviation from the more standard "miles per gallon" metric used for most vehicles.
The M1 Abrams' fuel economy is significantly poorer than that of comparable tanks, such as the German-made Leopard 2. A 1990 study by the Washington, D.C.-based Project on Government Oversight concluded that the M1 Abrams burns 83% more fuel than the Leopard 2 at the same speed. This disparity in fuel efficiency has led to discussions about converting Abrams tanks to diesel engines, which would facilitate the use of common fuel and potentially simplify repair processes, albeit with the trade-off of increased engine complexity.
The M1 Abrams' fuel consumption has significant logistical implications. The tank requires a continuous and substantial supply of fuel, necessitating a robust logistics chain. This challenge is further exacerbated by the distance between fuel depots and the front lines, which increases the time required for tanker trucks to deliver fuel. The large fuel demand of the M1 Abrams is not an isolated issue, as all tank engines face the challenge of powering heavy vehicles over rough terrain.
The decision to supply M1 Abrams tanks to Ukraine has brought the issue of fuel into sharp focus. Ukraine's ability to secure a steady supply of the required jet fuel has been questioned, and it remains a critical consideration for the successful deployment and utilisation of these tanks. The M1 Abrams' fuel needs extend beyond the fuel itself, as the engine also requires a special additive due to the lack of lubricating properties in jet fuel. This additive is necessary to prevent issues when running a diesel engine designed for traditional diesel fuel.

The fuel's cost
The M1 Abrams tank is a powerful machine, but its fuel consumption is a notable drawback. The tank's engine consumes an estimated 1.5 to 3 gallons per mile, which is an exceptionally high amount compared to other vehicles, including muscle cars and other tanks. This means that the Abrams tank needs a constant and substantial supply of fuel to keep running.
The Abrams tank was designed to run on jet fuel, specifically JP-8 aviation fuel. This type of fuel is not as readily available as diesel fuel, which is used by most other armored vehicles, including the German-made Leopard 2. The use of jet fuel contributes to the high fuel consumption of the Abrams tank, as it burns less efficiently than diesel.
The Abrams tank's gas-turbine engine can technically operate with a variety of fuels, including diesel, jet fuel (Jet A, Jet B, JP4, JP5, JP8), kerosene, home heating oil, and gasoline. However, the use of jet fuel is standard, and it is not clear how well the engine performs with other fuel types. Additionally, some fuels may require additives to compensate for their lack of lubricating properties, as is the case with commercial diesel.
The high fuel consumption of the Abrams tank has been a concern in the context of providing these tanks to Ukraine. There are logistical challenges in ensuring a steady supply of the required jet fuel to the front lines. Ukraine already faces fuel shortages, and the Abrams tank's appetite for fuel adds to the challenge of keeping it operational in a combat zone.
Converting the Abrams tank's engine to diesel has been considered, which would address the issue of fuel supply and potentially improve fuel efficiency. However, such a conversion would also introduce new challenges, such as increased maintenance needs due to the engine's more complex design.

Fuel availability in Ukraine
Fuel availability has been a critical issue in Ukraine since the Russian attack. The conflict has disrupted the country's fuel supply chains, causing shortages and long lines at petrol stations. Before the war, Ukraine imported 80% of its oil products, with Russia and Belarus supplying 62% of its gasoline and 44% of its diesel. These sources have been cut off, leading to a fuel crisis that has impacted civilians, farmers, and the military.
Ukrainian civilians have faced fuel disruptions, long waits at petrol stations, and restrictions on fuel purchases. The Russian blockade of Black Sea ports has prevented tanker replenishments, and attacks on energy infrastructure and transportation bottlenecks have exacerbated the shortages. President Volodymyr Zelensky pledged to address the shortages, blaming the occupiers for deliberately destroying fuel infrastructure.
Ukrainian farmers, who use a significant amount of diesel for their activities, have been hit hard by the fuel crisis. They have lost about 85% of their normal fuel supplies since the conflict began. This has resulted in a smaller total area planted with grain and potential drops in yield if fuel is not secured for applying chemicals and harvesting crops.
The Ukrainian military has also faced fuel-related challenges. The supply of M1 Abrams tanks from the United States, which run on jet fuel or diesel, has raised concerns about the steady provision of the required fuel types. However, some sources suggest that the Ukrainian military has secured fuel supplies through agreements with European suppliers, utilizing the country's railroad system for transportation.
