Some semi-trucks have multiple tanks to travel further
The fuel capacity of a semi-truck depends on the number of tanks and their sizes. Some semi-trucks have multiple tanks, allowing them to travel longer distances without refuelling.
A typical semi-truck with a single tank holds 105 gallons of fuel. However, some semi-trucks have multiple tanks, enabling them to carry more fuel and extend their range. The additional weight of the extra fuel and tanks is an important consideration, as it affects the overall weight of the truck and influences its performance and road safety.
The weight of diesel fuel is approximately seven pounds per gallon. When filled to capacity, a standard semi-truck tank with multiple tanks can weigh around 735 pounds. While this increases the truck's range, it also adds to the overall weight, impacting fuel efficiency and performance.
To manage weight distribution and maximise fuel efficiency, the Federal Motor Carrier Safety Administration recommends filling the tank to only 95% capacity. This allows for fuel expansion and helps prevent spillage. For example, a 120-gallon tank filled to 95% capacity would weigh approximately 798 pounds, while a 150-gallon tank would weigh around 998 pounds at the same fill level.
Customised fuel tanks are also available for semi-trucks, offering larger capacities of 160, 260, or 400 gallons. These options provide even greater fuel capacity, allowing semi-trucks to travel extended distances without frequent refuelling stops.

A full tank impacts maximum load allowance
The weight of a full tank of fuel impacts a semi-truck's maximum load allowance. Semi-trucks have a weight capacity of between 70,000 and 80,000 pounds. Companies employing semi-truck drivers will want to get as close to this maximum as possible to offset the high costs of paying drivers. However, exceeding the maximum weight can have severe consequences. It can damage the truck and its engine, cause road damage, and result in fines for the operator or trucking company.
The weight of a full tank of fuel is influenced by the number of tanks and their size. Some semi-trucks have multiple fuel tanks, allowing them to travel longer distances without refuelling. A standard configuration semi-truck tank typically holds 105 gallons of fuel, weighing around 735 pounds when full. Customised semi-truck tanks are available in larger sizes, commonly 160, 260, or 400 gallons.
The weight of diesel fuel is approximately seven pounds per gallon. Therefore, a semi-truck with a 300-gallon fuel capacity can be expected to weigh about 2,100 pounds. This weight consideration is essential because it directly impacts the maximum load allowance. The load standard guidelines are in place to ensure the safety of everyone on the road.
While a full tank is desirable at the start of a journey, most truck drivers follow the 95% rule, filling their tanks to only 95% capacity. This precaution allows for fuel expansion and prevents spillage. For example, a 120-gallon tank filled to 95% capacity would weigh 798 pounds, while a 150-gallon tank would weigh 998 pounds. This weight calculation is crucial for trip planning and determining shipping abilities, considering the maximum load capacity includes cargo, truck weight, and fuel.
Additionally, the terrain and temperature can impact the weight of the fuel. Diesel fuel is affected by temperature changes, contracting in cold weather and expanding with increasing temperatures. These factors can influence the overall weight of the truck and, consequently, the maximum load allowance.
