Tanker Truck Fuel Capacity: A Closer Look at Volumes and Design
In 2007, the U.S. consumed over 20 million barrels of oil daily, while China used about 7.5 million barrels per day, according to Nation Master. Tanker trucks are responsible for delivering the oil used for transportation in the United States. (See reference 2.)

Nearly 25 million gallons of fuel are made in the Los Angeles area per day,
According to Nation Master, the United States consumed more than 20 million barrels of oil per day in 2007. China ranked second, using approximately 7.5 million barrels daily. In the U.S., tanker trucks are the vehicles that transport oil for transportation purposes. (See reference 2.)
Single-tank trucks
Single-tank trucks with two axles can hold 3,000 gallons. Those with three axles have a 5,000-gallon capacity. (See reference 1.)
Semi-trucks
A semi-trailer truck is equipped with a single tank. This tank, roughly 40 feet wide, can contain 9,000 gallons. (See reference 1.)
Materials
Aluminum is the typical material for these tanks. They are designed to be lightweight so they can carry more fuel. (See reference 1.)
Construction
Typically, tanks are built with two to four compartments. Bulkheads divide these compartments. When tanks are used for different flammable materials, double bulkheads are required. (See reference 1.)
Unloading
Unloading fuel from tankers occurs from the bottom. The fuel flows by gravity through valves within the tanker. These valves are operated by air, mechanically, or both. (See reference 1.)
