6 Tips to Improve Your Semi-Truck Fuel Economy This Year

In long-haul transportation, semi-trucks play an indispensable role, moving goods across vast distances and ensuring economies thrive. Given the significant miles that these trucks cover, fuel economy isn’t just a term; it’s a crucial aspect of operations, both from an environmental and financial perspective. 

By achieving better fuel efficiency, semi-truck operators not only reduce expenses but also contribute to a greener environment by cutting down on carbon emissions. In this article, we will discuss some actionable tips that can significantly improve your semi-truck fuel economy this year.


The Basics of Fuel Economy

Fuel economy refers to the distance a vehicle can travel on a unit of fuel, typically measured in miles per gallon (mpg) or kilometers per liter (kmpl). For semi-trucks, with their large fuel tanks and immense weights, achieving a commendable fuel economy is a bit more complex than with smaller vehicles. The reason fuel economy is paramount for semi-truck operators boils down to two primary factors:

  1. Cost Savings: Fuel is often one of the most considerable operational costs for trucking companies. Even a slight improvement in fuel efficiency can result in substantial annual savings.
  2. Environmental Responsibility: Efficient fuel use leads to fewer emissions, making a direct contribution to a cleaner environment. This not only aids in meeting environmental regulations but also bolsters a company’s green initiatives.


6 Ways to Improve Your Semi-Truck Fuel Economy

1. Optimize Tire Maintenance

Tires are more than just the point of contact between the semi-truck and the road; they play a pivotal role in determining fuel efficiency. Under-inflated tires create higher rolling resistance, meaning the engine has to work harder and thus burns more fuel. On the other hand, over-inflated tires can reduce traction and wear out prematurely. Therefore, maintaining the correct tire pressure is imperative. Check tire pressures regularly, ideally during every fuel stop, and always ensure they align with the manufacturer’s recommendations.

Misaligned tires, or tires that aren’t rotated appropriately, can wear out unevenly and decrease fuel efficiency. Ensure regular check-ups for alignment and commit to a consistent tire rotation schedule to prolong tire life and maintain optimum fuel economy.


2. Plan Efficient Routes

Mapping out the most efficient route for a journey requires more logistics than just calculating the shortest distance between two points. Time spent in congested traffic not only delays shipments but also consumes fuel inefficiently. Leveraging real-time traffic data can help drivers anticipate and avoid congested routes.

Modern GPS devices and software come equipped with route optimization features that factor in variables like traffic, terrain, and even weather conditions. This ensures that the chosen route is not only short but also conducive to better fuel efficiency. Every time a semi-truck stops and starts, it consumes extra fuel. By planning routes that bypass towns with frequent stop signs or intersections, one can maintain a consistent speed and optimize fuel consumption.


3. Reduce Excessive Idling 

The hum of a semi-truck engine idling might seem harmless, but it’s a silent fuel consumer that adds unnecessary expenses over time. On average, a semi-truck consumes about a gallon of fuel per hour of idling. Over prolonged periods, this can add up to significant fuel wastage, not to mention the additional wear and tear on the engine.

Auxiliary power units (APU) can provide power for the truck’s essential functions without the need to keep the main engine running. By using an APU during rest periods, drivers can save fuel and reduce emissions. Ensuring drivers understand the financial and environmental implications of excessive idling is crucial. A well-informed driver is more likely to turn off the engine during longer waits.


4. Regular Engine Maintenance

Dirty air and fuel filters make a semi-truck’s engine work harder than necessary, reducing fuel efficiency. Regularly changing these filters ensures that the engine receives clean air and fuel, optimizing performance. Using the right grade of engine oil and changing it at regular intervals reduces friction in the engine, leading to better fuel economy.

Routine inspections can identify issues like fuel leaks or malfunctioning components before they become major problems. Addressing these issues promptly ensures that the engine continues to operate at peak efficiency.


5. Improve Aerodynamics

Air resistance, or drag, plays a significant role in the fuel consumption of a semi-truck, especially at highway speeds. By optimizing the aerodynamics of a truck, you can substantially reduce this drag and boost fuel economy.

Devices such as cab extenders, side skirts, and air deflectors can streamline the airflow around the truck, reducing turbulence and drag. Remove or redesign external equipment that disrupts airflow, such as large mirrors or non-essential attachments. The smoother the profile of the truck, the better the aerodynamics.

Modern trailers are being designed with aerodynamics in mind. Consider upgrading to a more aerodynamically efficient trailer if it aligns with your operational needs.


6. Educate & Train Drivers

Even the most fuel-efficient truck can guzzle fuel if not driven correctly. The driving habits of your fleet’s operators play a pivotal role in determining fuel economy. Educate drivers about practices such as progressive shifting, maintaining a steady speed, and using cruise control effectively.

Smooth driving, without abrupt accelerations and decelerations, conserves fuel. Regular training sessions can instill these habits in drivers. Modern trucks come equipped with systems that provide real-time feedback on driving habits. Use this data to guide drivers towards more fuel-efficient behaviors. In some cases, a well-trained driver can improve fuel economy by margins of nearly 10%, showcasing the importance of continuous education in the trucking industry.
