How Far Can a Truck Go on One Tank of Fuel: The Corollary of Over the Road (OTR) Driving

As an OTR truck driver, you might often wonder how far one tank of fuel can take you, especially when you're navigating through vast distances. The answer to this question isn't straightforward, as several factors come into play. In this article, we'll explore the variables that influence fuel efficiency and travel distance for OTR trucks.

Factors Affecting Fuel Efficiency

Truck fuel efficiency is not as simple as just looking at the miles per gallon (mpg). Several factors can influence how far a truck can travel on a single tank of fuel. These include tank capacity, terrain, load weight, and driving conditions.

Truck Fuel Tank Capacity

Most OTR trucks have two standard fuel tanks, each typically ranging from 150 to 300 gallons. For example, a truck with a 200-gallon tank @ 7 MPG would allow you to travel approximately 1400 miles. However, this can vary, and trucks with larger tanks can certainly go farther between fills. It's not uncommon to see trucks with twin 200-gallon tanks or even twin 75-gallon tanks, which can significantly impact travel distance.

Driving Conditions and Terrain

The terrain under which a truck drives plays a crucial role in determining fuel efficiency. A truck running across flat land in Nebraska will travel further than the same truck with the same load driving through Colorado's mountainous regions. Wind conditions, whether favorable or not, also affect fuel consumption.

Truck Design and Load Type

The design of the tractor and the trailer can also influence fuel efficiency. An aerodynamic tractor pulling a standard van trailer will travel further than a classic-styled, square-hood tractor pulling an oversized load. Additionally, the load itself, whether heavy or light, can affect fuel consumption.

Examples of Travel Distance

For those considering a trip from Missouri to Los Angeles, which is approximately 1600 miles, or to Oakland, which is around 1835 miles, fuel considerations are paramount. If you're based in Missouri and looking to save on fuel costs, you might consider filling up with cheaper fuel, then running the distance to your destination.

Most OTR trucks have two 150-gallon saddle tanks, giving roughly 1800 miles with a fuel efficiency of around 6 MPG. This means that the average OTR truck can travel about 900 miles on 490 liters of fuel during heavy haul work. However, this can vary greatly depending on the specific conditions and truck setup.

Practical Considerations

While distance and fuel efficiency are crucial metrics for an OTR driver, there are additional practical considerations that can affect travel decisions. Running out of fuel is not only inconvenient but also potentially dangerous. Truckers must be prepared to cover their fuel costs, particularly in relation to their duties for road use taxes.

Additionally, drivers must ensure they maintain a sufficient fuel reserve to avoid running out of fuel. If you find yourself in a situation where you need to refuel but can't complete your trip, you'll need to seek assistance, which can be time-consuming and costly.

Conclusion

There is no single, definitive answer to how far a truck can go on one tank of fuel. Factors such as tank capacity, driving conditions, load type, and truck design all play a role. While it's possible to estimate the distance based on these factors, the variability means that an accurate answer is elusive. Nevertheless, understanding the factors that influence fuel efficiency is essential for any OTR driver.
