Armed conflict consumes unimaginable amounts of gasoline and diesel fuel. How much do you know about the fuel efficiency of war machines? Take this quiz to find out.

# The mine-clearing Buffalo A2 has a 12.5-liter (3.3-gallon) engine that gets about how many miles per gallon?

The Buffalo A2, which was featured as a robot in the "Transformers" movie, gets about 3.5 miles per gallon.

# In World War II, the U.S. armed forces used about how many gallons of fuel per soldier per day?

Considering the scope of this conflict, 2 gallons per soldier per day wasn't much fuel.

# The U.S. military uses about how many barrels of oil each year?

If you had a vehicle that averaged 25 miles per gallon, you could take 4 million trips around Earth using 100 million barrels of oil.

# In 2007 the United States armed forces used about how many gallons of fuel per soldier per day?

The armed forces used about 27 gallons of fuel per soldier per day. The U.S. Department of Defense is the largest fuel consumer in the world.

# The C-5 Galaxy cargo jet has a miles-per-gallon rating of about what?

Only America can afford to burn fuel at 0.07 mile per gallon.

# Vortex surfing, similar to geese flying in formation, might help Air Force planes save about how much fuel on a flight?

It might help the planes save 8 percent of their fuel, but the maneuver requires special training.

# What is the miles-per-gallon rating for the 19-ton (17,237-kilogram) Stryker armored vehicle?

Considering its heftiness, it is surprisingly efficient. It gets 5.7 miles per gallon.

# What's the approximate miles-per-gallon rating of the F-22 Raptor fighter?

The 0.4 mile-per-gallon rating of the F-22 Raptor makes your grandpa's gigantic recreational vehicle seem really efficient.

# Compared to the A and B models, the C-5M Galaxy improves fuel efficiency by about what percentage?

Three percent doesn't sound like much, but over time this means a significant savings in fuel.

# Which branch of the U.S. military consumes the most fuel?

Jets burn fuel like it is going out of style.

# How much fuel does the U.S. Navy consume in the time it takes to fill a car's 20-gallon (76-liter) gas tank?

The Navy consumes 30,000 gallons of fuel in that time. It makes you wonder how refineries can keep pace with our consumption.

# Which branch of the U.S. military consumes the most diesel fuel?

Ships burn through incredible amounts of diesel.

# In an hour, how many pounds of fuel would an F-16 jet burn at full afterburner and low altitudes?

It would burn about 64,000 pounds of fuel. Afterburners provide huge thrust but at the expense of much higher fuel consumption.

# How many miles per gallon does an Army Humvee get?

Consumer Hummers get about 12 miles per gallon too.

# How much horsepower does an Arleigh Burke destroyer's engine generate?

It generates 110,000 horsepower, and it eats fuel like crazy, which is why bigger ships like aircraft carriers use nuclear power instead.

# The M1070, an Army semitrailer, has a 500-horsepower (372,850-watt) engine and a miles-per-gallon rating of what?

Fully loaded, they can only go about 30 miles per hour (48 kilometers per hour).

# What's the miles-per-gallon rating for the M1 Abrams tank?

It only gets 0.6 mile per gallon. You can't expect much better from a 60-ton (54,431-kilogram) vehicle.

# The M109A6 Paladin is a self-propelled howitzer with a 155-millimeter gun. How many miles per gallon does it get?

It only gets 1.3 miles per gallon. Army vehicles clearly do not stress fuel efficiency .

# How many gallons of fuel does the M1 Abrams tank carry?

It carries 500 gallons of fuel and has an operational range of about 300 miles (483 kilometers).

# At a low altitude and maximum afterburner power, how many gallons of fuel per hour does an F-15 fighter require?

It requires about 23,000 gallons of fuel per hour. That’s about 385 gallons every minute.

# The hybrid engines on the USS Makin Island saved about how much in fuel costs on its maiden voyage?

It saved about \$2 million on its first voyage. Over the life of the craft, the Navy expects to save about \$250 million in fuel expenses.

# If an F-15 uses its afterburner continuously, how long would its fuel supply last?

it would last about six minutes. In other words, the afterburner is for rare occasions only.

# About how many gallons of fuel might an Arleigh Burke-class destroyer use in a single hour?

It takes a lot of fuel to move such a huge boat — 1,000 gallons per hour to be exact.

# How much does the U.S. Navy spend each year on ship fuel?

It spends \$2 billion on ship fuel. The gas-turbine engines common to Navy ships are not very fuel efficient.

# How does speed affect a ship's fuel consumption?

Faster speeds mean bigger waves to push out of the way.

# About how many gallons of fuel per hour does the F-16 fighter jet require?

The jet uses about 800 gallons of fuel per hour. This is why the Air Force requires so much jet fuel.

# How many gallons of fuel did the U.S. Air Force consume in 2012?

Two billion gallons is a veritable ocean of jet fuel.

# The Bradley Fighting Vehicles are made to keep up with M1 tanks. What's their approximate miles-per-gallon rating?

Their heavy armor drastically reduces fuel efficiency, and they only get 1.7 miles per gallon.

# To save fuel, the U.S. Air Mobility Command considered removing what from planes?

Removing booklets and manuals could cut the weight of the plane by 130 pounds (59 kilograms).

# The World War II-era B-52 bombers burned through how many gallons of fuel per hour?

The immense bombers flew countless sorties through the conflict, burning 3,300 gallons of fuel per hour.
