What You'll Learn
The M1 Abrams tank uses 10 gallons of fuel to start up
The M1 Abrams tank is a gas guzzler. It uses 10 gallons of fuel to start up, and continues to burn through fuel at a rapid rate. When idle, the tank consumes 1 gallon of fuel every six minutes, and when travelling cross-country, it burns through 1 gallon of fuel every minute. This equates to around 1.5 to 3 gallons of fuel per mile, or approximately 0.57 miles per gallon.
The Abrams' AGT1500 Honeywell gas-turbine engine can run on any fuel that is thin enough to move through the lines. This includes jet fuel, leaded gas, marine diesel, and even questionable heating oil. The tank's high fuel consumption is a serious logistical problem, and it is estimated that the Abrams burns through 83% more fuel than the German-made Leopard 2 at the same speed.
Despite its fuel inefficiency, the gas turbine propulsion system has proven reliable in practice and combat. The turbine is also very quiet when compared to diesel engines of similar power output, producing a high-pitched whine that earned the Abrams the nickname "whispering death".
Efforts have been made to improve the fuel efficiency of the M1 Abrams. For example, the U.S. Army explored converting Abrams tanks to diesel engines, which would allow for common fuel and more familiar repair needs. Additionally, a replacement turbine is in development, which is expected to reduce fuel consumption by 33%.

It burns 1.5-3 gallons per mile
The M1 Abrams tank is estimated to burn between 1.5 and 3 gallons of fuel per mile. This figure is dependent on the version of the tank, with the M1A2 models having improved fuel efficiency over the original M1. The M1 Abrams is known for its high fuel consumption, which has been a significant logistical problem for the Army.
The tank's AGT1500 Honeywell gas-turbine engine can run on a variety of fuels, including jet fuel, diesel, leaded gas, and marine diesel. This versatility in fuel type can be advantageous in certain situations, as described by a former U.S. Army tanker who claimed that his tank ran on whatever fuel they could find. However, the trade-off is the M1's high fuel consumption, which makes even the most gas-guzzling muscle car seem fuel-efficient in comparison.
The M1 Abrams' fuel efficiency is further impacted by the fact that it consumes a significant amount of fuel when idling, using 1 gallon of fuel every six minutes while idle and 1 gallon every minute when traveling cross-country. Additionally, it requires 10 gallons of fuel just to start up the engine. These factors contribute to the M1 Abrams' reputation for being particularly "thirsty," even among third-generation main battle tanks (MBTs).
Despite the M1 Abrams' high fuel consumption, efforts have been made to improve its fuel efficiency. For example, the Army has explored converting Abrams tanks to diesel engines, which would allow for common fuel and more familiar repair needs.

It can run on various types of fuel
The M1 Abrams tank is estimated to use between 1.5 and 3 gallons of fuel per mile, which is extremely inefficient even when compared to other tanks. The M1 Abrams is powered by a gas-turbine engine, which was designed to burn jet fuel, although it is capable of running on a variety of different fuels.
The M1 Abrams tank burns through fuel at an alarming rate, consuming nearly three-quarters as much fuel as a Tiger tank of 1941. It takes 10 gallons of fuel just to start up the tank, and it continues to burn 1 gallon of fuel every six minutes when idle, and 1 gallon every minute when travelling cross-country.
Despite being designed to run on jet fuel, the M1 Abrams tank can technically run on any sufficiently thin flammable liquid. This includes gasoline, diesel, kerosene, and even alcohol. The Australian Army's M1s have run on diesel without any problems, and one former U.S. Army tanker claimed to have operated the M1 using various alternative fuels, including "questionable heating oil".
The ability of the M1 Abrams tank to run on a variety of fuels is a significant advantage, providing flexibility and adaptability in different operational contexts. However, the amount of fuel it consumes remains a challenge, particularly in large-scale deployments or in areas where fuel supply lines are difficult to establish or maintain.

It has a 289-mile operational range
The M1 Abrams tank is listed as having a 289-mile (approximately 466-kilometre) operational range. This equates to 0.57 miles per gallon, with a fuel capacity of 500 US gallons (1900 litres). The M1 Abrams is a gas-guzzler, even among third-generation MBTs. It consumes 10 gallons of fuel to start up, 1 gallon every six minutes when idle, and 1 gallon every minute when travelling cross-country.
The M1 Abrams' AGT1500 Honeywell gas-turbine engine can run on any fuel that is thin enough to move through the lines. It can run on gasoline, diesel, jet fuel, leaded gas, marine diesel, or even pure ethanol. The turbine-powered M1 can churn up at least 12,000 miles without an overhaul. The power pack never needs an oil change, and it operates on No. 2 diesel. The M1 Abrams' high fuel consumption is a serious logistical problem.
The M1 Abrams' fuel efficiency has improved significantly from the M1 to the M1A2 models due to a range of small improvements. One of the biggest overlooked factors with tanks is their fuel consumption while idle or at very low speeds (under 5 mph). Tanks spend a significant amount of time idle, and they take a short while to warm up enough to move after hitting the "Start" button. A replacement turbine is in development, which will reduce fuel consumption by 33% (50% at idle).

The M1A2 model has reduced fuel consumption
The M1 Abrams is a third-generation American main battle tank designed by Chrysler Defense (now General Dynamics Land Systems). It was conceived for modern armored ground warfare and is one of the heaviest tanks in service at nearly 73.6 short tons (66.8 metric tons). The M1 Abrams uses a lot of fuel, with estimates ranging from 1.5 to 3 gallons per mile. It consumes 10 gallons of fuel to start up, 1 gallon every six minutes when idle, and 1 gallon per minute when traveling cross-country.
The M1 has gone through several configurations since its introduction in 1983. The original M1 had a relatively small main gun and limited armor. This was followed by the M1A1 in the late '80s, which featured a larger gun and improved armor. The newest variant is the M1A2, which is characterized by vastly improved onboard electronics and additional armor.
Additionally, the M1A2 features a more advanced fire control system, which likely contributes to more efficient fuel usage. The commander's machine gun on the M1A2 uses the Common Remotely Operated Weapon Station (CROWS) system, which provides enhanced situational awareness and improved targeting capabilities. This remote weapon station has a low profile, reducing the vehicle's overall signature on the battlefield.
The M1A2's multifuel turbine engine can run on various types of fuel, including ordinary gasoline, diesel fuel, jet fuel, and even questionable heating oil in a pinch. This flexibility in fuel choice can help improve operational efficiency and reduce logistical burdens, especially in environments where fuel supply lines may be disrupted or inconsistent.
