Knowing the fuel capacity of a semi truck is crucial for planning long-haul trips and managing fuel costs. In this article, we will delve into the details of semi truck fuel tanks, their sizes, and how far a truck can go on a full tank.

Key Takeaways

• A standard semi truck can hold 105 gallons of fuel.
• Customized semi truck tanks can have capacities of 160, 260, or 400 gallons.
• The average gas mileage for a semi truck is 6.5 miles per gallon.
• Some semi trucks come with more than one fuel tank for extended travel.
• A gallon of diesel fuel typically weighs about 7 pounds.

How Many Gallons Of Gas Does A Semi Truck Hold?

A standard semi truck typically has a fuel tank that can hold 105 gallons of fuel. However, customized fuel tanks can have capacities of 160, 260, or even 400 gallons.

These custom tanks are useful for businesses that require their trucks to travel greater distances without stopping for refueling.

Standard Configuration

In a standard configuration, a semi truck will generally have a fuel tank that holds 105 gallons. This is the most common size and is adequate for most trucking needs.

Customized Tanks

For those who need to travel greater distances without refueling, customized tanks are available. These can have capacities of 160, 260, or 400 gallons.

Factors Affecting Travel Distance

The distance a semi-truck can travel on a full tank depends on several factors:

Number of Fuel Tanks

Some semi trucks are equipped with more than one fuel tank, allowing them to travel greater distances without stopping for fuel.

Weight of Fuel and Tanks

A gallon of diesel fuel typically weighs about 7 pounds. Therefore, a standard 105-gallon tank would weigh approximately 735 pounds.

Gas Mileage

The average gas mileage for a semi-truck is about 6.5 miles per gallon. So, a truck with a 300-gallon tank could expect to travel about 2,100 miles before needing to refuel.

Commercial Fuel Bulk Delivery

Bulk delivery services are available for businesses that require large quantities of fuel. These services can deliver diesel, biodiesel, and gasoline directly to your location.

Fleet Fueling Services

Many companies offer fleet fueling services that provide 24/7 access to fueling stations, making it easier to manage fuel consumption for a large number of vehicles.

More Insights on Semi Truck Fuel Capacity

We will delve deeper into some of the nuances of semi-truck fuel capacity. We’ll cover the 95% rule for fueling, the weight of diesel fuel, and why you should never let your fuel tank drain completely. Let’s get started.

The 95% Rule for Fueling

When it comes to filling up a semi truck’s fuel tank, it’s generally advised to fill up to 95% of the total fuel capacity. This rule serves multiple purposes:

Risk of Spilling

Overfilling the tank could lead to diesel fuel spilling out via the overflow valves. This not only wastes fuel but also poses environmental risks.

Diesel Expansion

The fuel can expand or contract based on the ambient temperature, affecting the weight of your fuel. Adhering to the 95% rule helps mitigate these issues.

Never Drain Your Tank Completely

Most truckers make it a point never to let their fuel tank go below 25%. This is because:

Contaminant Accumulation

Dirt and bacteria tend to accumulate at the bottom of large fuel tanks. The suction system is designed to avoid drawing from the very bottom to prevent these contaminants from entering the engine.

Weight of Diesel Fuel

Understanding the weight of diesel fuel is crucial for truckers. A gallon of diesel generally weighs 7 pounds, making a full tank weigh between 840 to 1,050 pounds. This weight plays a significant role in decisions about whether to use one or two fuel tanks.

Weight Variations

The weight of the fuel can also vary slightly with temperature changes, although these variations are usually less than half a pound.

Additional Resources

For those looking to delve deeper into the subject or find great deals on used trucks, resources like International Used Truck Centers offer valuable information and financing tips.

How Much Does The Fuel In A Semi Truck Gallon Weigh?

The weight of diesel fuel is an essential factor for truckers to consider, especially when it comes to complying with weight regulations.

A gallon of diesel fuel generally weighs about 7 pounds. However, this weight can slightly vary depending on the temperature.

For example, at 16 degrees Fahrenheit, one gallon of diesel fuel weighs 7.1 pounds, while at 106 degrees Fahrenheit, it weighs 6.8 pounds.

These minor differences can add up, especially when you have a large fuel tank that can hold up to 300 gallons.

In such cases, the temperature-weight difference of diesel fuel will never be more than 10-50 pounds depending on the size of the fuel tank.

How Much Fuel Do You Need To Put In A Semi-Truck?

When fueling a semi-truck, it’s generally advised to fill up to 95% of the total fuel capacity. This is known as the 95% rule for fueling, which helps to prevent the risk of spilling and accounts for diesel fuel expansion due to temperature changes.

Additionally, you should always factor in the amount of fuel you are carrying before you hit the scales.

If you have 100 gallons of diesel in your tank, that’s about 700 pounds added to your truck weight. Overestimating your truck’s weight mentally ensures that it remains within weight limits when it sits on the scale.

How Many Gallons Does It Take To Fill Up A Big Rig?

The fuel capacity of a semi-truck can vary significantly depending on its make and model. However, semi-truck fuel tanks generally hold an average of 125 to 300 gallons of fuel.

A fuel tank sits on each side of the tractor, and fuel is distributed between the two tanks to balance the truck’s total weight.

Therefore, filling up a big rig could require anywhere from 125 to 300 gallons of diesel fuel, weighing between 875 to 2,100 pounds when full.

How Many Gallons Of Gas Does A Semi-Truck Haul?

Semi-trucks are designed to be fuel-efficient for long-haul journeys, but they still require a significant amount of fuel. A standard semi-truck generally has two fuel tanks, each with a capacity ranging from 120 to 150 gallons.

When combined, these tanks can hold approximately 300 gallons of diesel fuel. These tanks are strategically placed on each side of the tractor to balance the truck’s total weight.

Knowing the exact fuel capacity is crucial for truck operators due to varying transportation laws that might differ from one place to another.

For instance, without knowing the accurate tank capacity and the fuel weight, the semi-truck operator could risk incurring heavy fines for unlawful transportation of goods.

Things To Consider When Filling Up Your Semi-Truck Fuel Tank

Filling up a semi-truck’s fuel tank isn’t as straightforward as it might seem. There are several factors to consider:

1. Size of The Fuel Tank: Not all fuel tanks are designed the same. The industry standard is a tank with a fuel capacity of around 120 to 150 gallons. Larger tanks are used for long-distance travel.
2. Type of Semi-Truck: The type of semi-truck you’re driving can influence the fuel capacity. Trucks designed to carry heavier loads will naturally have larger fuel tanks.
3. Aerodynamics: A well-designed, aerodynamic truck will consume less fuel, affecting how much fuel you’ll need to fill.
4. Fuel Weight: A gallon of diesel usually weighs around 7 pounds, which can add significant weight to your truck.
5. The 95% Rule: It’s generally advised to fill up to 95% of the total fuel capacity to prevent the risk of spilling and to account for fuel expansion due to temperature changes.

By considering these factors, you can more accurately gauge how much fuel you’ll need and how it will affect your truck’s weight, thereby ensuring you stay within legal limits.

Conclusion

Understanding how many gallons of gas a semi truck holds is crucial for anyone in the trucking industry. Whether you opt for a standard 105-gallon tank or a customized one with greater capacity, knowing your fuel needs is essential for efficient operation and cost management.
