Top 7 ways to improve fuel economy in a semi-truck

1. Use Fuel-Efficient Driving Methods

Did you know that adopting efficient driving habits can cut fuel consumption by as much as 20%? That’s a significant saving, especially for owner-operators who rely on every drop of fuel to maximize profits. In fact, a study by the American Trucking Associations‘ Technology and Maintenance Council revealed a 35% gap in fuel efficiency between the best and worst drivers. This shows just how much of a difference consistent, fuel-conscious driving can make.

Keep Speed Between 55-65 MPH

Managing your speed is one of the simplest ways to save fuel. Research shows that fuel economy starts to drop sharply at speeds over 50 to 55 mph. For example, for every 1 mph increase above 55 mph, fuel efficiency decreases by 0.1 mpg. Driving at 55 mph can improve fuel efficiency by 43% compared to speeding along at 75 mph. Even driving at 65 mph offers a 22% improvement.

Additional studies back this up. According to the AA, driving at 70 mph uses up to 9% more fuel than at 60 mph and 15% more than at 50 mph. Push it to 80 mph, and fuel consumption can jump by 25% compared to cruising at 70 mph. Using cruise control on flat highways can help maintain a steady speed, reducing the fuel-wasting effects of constant speed fluctuations.

But speed isn’t the only factor. How you handle your acceleration and braking also plays a big role.

Accelerate and Brake Gradually

Smooth driving techniques can make a huge difference. Rapid starts and hard braking can increase fuel consumption by up to 40%, while aggressive driving can lower fuel efficiency by as much as 30% on highways. Tests have shown that harsh acceleration and braking don’t save much time – just 4% less travel time – but they cause harmful emissions to skyrocket by over five times.

Even small speed variations can have a big impact. For instance, fluctuating your speed between 75 and 85 km/h every 18 seconds can increase fuel use by 20%.

"Every time you use your brakes, you waste your forward momentum… You will conserve fuel and save money by taking your foot off the accelerator and coasting to slow down instead of using your brakes." – Natural Resources Canada

By anticipating traffic and road conditions, you can maintain a more consistent speed and reduce unnecessary braking. Whenever possible, try coasting to slow down rather than immediately hitting the brakes.

Consistency is the real game-changer. Research shows that speeding contributes to 33% of fuel waste, hard acceleration accounts for 25%, and hard braking makes up 6%.

"The key to success with each of these behaviors is consistency. Even small changes in behaviors can lead to improved fuel efficiency and significant cost savings over time." – TBS Factoring

2. Use Route Planning Technology

Efficient route planning can significantly lower fuel costs. In fact, GPS systems alone can reduce expenses by an average of 9%. Considering that fuel can make up as much as 40% of fleet operation costs, using route optimization software offers a powerful solution. This technology can cut fuel costs by up to 30%, while also improving routing efficiency and reducing wasted time by as much as 30%. A key element in this is leveraging live traffic data to refine routing tools.

Choose GPS with Live Traffic Data

Opt for GPS systems that provide real-time updates based on traffic, road conditions, and terrain. These systems help drivers avoid unnecessary delays and extra mileage. Heavy traffic or indirect routes can increase fuel consumption by as much as 30%, making real-time adjustments crucial for efficiency.

The evolution of technology continues to enhance these systems. Tim Peters, Chief Marketing Officer at Enghouse Systems, highlights the potential of emerging trends:

"Future trends point towards AI-powered predictive analytics, enabling smarter route planning and vehicle maintenance, and 5G integration… [This] will revolutionize data transmission speed for real-time updates."

Modern GPS tools do more than just guide routes. They also monitor vehicle performance, flagging potential maintenance issues early. This proactive maintenance scheduling prevents costly breakdowns and ensures trucks operate at peak fuel efficiency.

Well-known navigation tools like Google Maps and Waze provide real-time traffic data to help avoid congestion and accidents. Meanwhile, trucking-specific GPS systems offer tailored features like truck-friendly routes, which account for vehicle size, weight, and road restrictions.

Plan Direct Routes

While real-time updates are essential, planning direct and efficient routes from the start is equally important. Smart route planning goes beyond simply finding the shortest distance. It uses algorithms that consider factors like traffic, road grades, and speed limits to maximize fuel efficiency.

Advanced software can reduce mileage by 10–25% and lower operating costs by up to 15%. When planning routes, take topography and road types into account – flatter roads and paved surfaces are more fuel-efficient, while hills and rough terrain force engines to work harder and consume more fuel. Even small elevation changes can have a noticeable impact on fuel economy over long trips.

Regularly updating routes to reflect current traffic and road conditions is also key. Planning trips in advance helps eliminate unnecessary miles, avoid delays, and improve overall fuel efficiency. On the other hand, last-minute routing changes often lead to inefficient paths and wasted fuel. Coordinated planning also makes multiple-stop trips smoother, with less backtracking.

Automated routing systems streamline this process by replacing manual spreadsheets with real-time, integrated data, reducing the risk of human error.

UPS exemplifies this approach in their fleet strategy:

"Our fleet strategy is making the best of today’s transportation technology through careful route planning that avoids unnecessary driving and saves fuel."

Dan Popkin, Senior Vice President of Enterprise Solutions at ALK Technologies, emphasizes how navigation has evolved:

"These solutions get away from static routing and enable dynamic routing processes… They transform navigation into a strategic tool for fuel savings."

3. Join Fuel Discount Programs

Fuel discount programs are a straightforward way to cut down on fuel expenses. For owner-operators, fuel often represents 23% of annual revenue – up to $70,000 per year. Even small savings per gallon can quickly add up, making a big difference to the bottom line.

Fuel cards, for example, can save between $0.50 and $0.68 per gallon. Over time, these discounts translate into significant savings, with some users, like those with the DAT One Fuel Card, reporting average monthly savings of $500 per truck.

These cards typically use one of two discount models. Retail-minus pricing subtracts a discount from the listed cash price, while cost-plus pricing adds a small fee to the station’s fuel cost, which includes taxes and delivery charges. Some cards even offer a "Better Of" option, which automatically applies the method that yields the largest discount.

Brian Webb, Multi Service Fuel Card Director of Sales, succinctly explains:

"If you’re paying retail price, you’re purchasing fuel the wrong way."

This approach works well alongside other fuel-saving strategies, which we’ll explore in later sections.

Compare and Track Fuel Prices

Making smart fuel purchases starts with comparing prices and monitoring your spending. Most fuel cards are tied to specific networks, meaning they work best at certain fuel chains, though some allow out-of-network purchases with reduced benefits. When evaluating fuel programs, look at the coverage along your routes, the type of discounts offered, and any additional perks or fees.

Fuel cards offer more than just savings. They provide detailed purchase reports, simplifying tax filing and International Fuel Tax Agreement (IFTA) reporting. Many also include security features like fraud protection and tax-ready reporting, making them more efficient than traditional credit cards.

Understanding which gas stations and truck stops are part of your program is key to maximizing savings. Fleet owners who skip out on fuel discount opportunities leave money on the table.

Access Booker Transportation Services Benefits

Some programs go beyond standard discounts, like those offered by Booker Transportation Services, which tailors fuel savings for owner-operators. Booker’s fuel discount program leverages bulk pricing and supplier-specific deals that individual operators wouldn’t typically have access to.

To put this into perspective, filling a semi-truck’s 300-gallon tank costs about $1,665 at the nationwide average of $5.55 per gallon. Even small savings per gallon can lead to significant reductions in monthly expenses.

For owner-operators who average 7 miles per gallon and drive around 3,000 miles weekly, fuel costs quickly add up. This makes a fuel card program particularly valuable, as it ensures consistent savings for those maintaining high mileage.

Booker’s program provides its leased owner-operators with fuel cards linked to managed accounts. These cards offer essential features like fraud controls, transparent expense tracking, and easy fund management. By leveraging the company’s purchasing power, owner-operators access discounts that wouldn’t be available to individual truckers.

This structure mirrors industry best practices, where carriers negotiate specialized programs to help their drivers save at the pump. For owner-operators, using these programs isn’t just smart – it’s essential for managing operating costs effectively.

4. Follow Regular Maintenance Schedules

Keeping up with regular maintenance is crucial for your truck’s performance. Skipping maintenance doesn’t just lead to mechanical problems – it also increases fuel consumption as the engine works harder to compensate for inefficiencies.

Bret McKinney, Director of Fuel at CRST, sums it up perfectly:

"The different parts of your truck all work together. A weak link can have an adverse effect on fuel and other areas."

Addressing a serious maintenance issue can boost your mileage by up to 40%. This makes routine upkeep one of the most effective ways to save fuel and ensure every part of your truck contributes to peak efficiency.

Complete Routine Service Checks

Simple tasks like oil changes, replacing air filters, and performing regular tune-ups go a long way in keeping your engine running smoothly. Ignoring these can lead to gradual performance declines and increased fuel consumption.

Tune-ups alone can enhance fuel efficiency by 4–40%. The impact varies because some issues, like a dirty air filter, may cause minor inefficiencies, while multiple worn-out components can significantly hurt your mileage.

Your maintenance checklist should cover filters, brake systems, and cooling systems to verify they’re functioning as intended. A preventative approach also helps you catch small issues – like low oil levels, clogged filters, or compressor leaks – before they snowball into bigger, costlier problems.

The PrePass Safety Alliance highlights the value of this proactive mindset:

"Preventative maintenance is an investment that pays off by reducing the likelihood of major component failures."

By addressing minor problems early, you not only avoid expensive repairs but also maintain fuel efficiency over your truck’s lifespan. Beyond engine care, tire maintenance plays a critical role in reducing rolling resistance and saving fuel.

Check Tire Pressure and Alignment

Keeping your tires properly inflated is one of the easiest ways to save fuel. Under-inflated tires increase rolling resistance, forcing your engine to burn more fuel. The scale of the problem is staggering: under-inflated tires waste about 5 million gallons of gas daily in the United States.

The numbers don’t lie. For every 1 psi drop in tire pressure, fuel efficiency decreases by 0.2%. That means a tire that’s 10 psi below the recommended level reduces your fuel efficiency by 2%. Over time, this adds up, especially when fuel costs are one of the biggest expenses for truck operators.

Proper tire inflation doesn’t just save fuel – it also extends tire life. Every 1 psi drop accelerates tire wear by 10%, meaning you’ll spend more on replacements if you don’t keep an eye on pressure.

Wheel alignment is just as important. Misaligned wheels create uneven tire wear and increase rolling resistance, which directly impacts fuel consumption. Regular alignment checks ensure your tires wear evenly and perform efficiently, helping you save on fuel and maintenance costs.

Before hitting the road, inspect both truck and trailer tire pressure. Look for leaks, punctures, and pressure inconsistencies during pre-trip checks. Additional steps like tire rotations, balancing, and alignments will extend the life of your tires while keeping fuel consumption in check.

For added convenience, consider installing tire pressure monitoring systems. These systems provide real-time alerts, so you can maintain optimal pressure levels without relying solely on manual inspections. Over time, this small investment can lead to significant savings.

5. Improve Tire Performance and Truck Aerodynamics

Choosing the right tires and making aerodynamic upgrades can significantly cut fuel costs and improve a truck’s efficiency. While these changes may require an upfront investment, the long-term savings and performance benefits make them worthwhile.

Install Low-Rolling-Resistance Tires

Low-rolling-resistance (LRR) tires are a game-changer for reducing fuel costs. Rolling resistance contributes to 30-33% of a Class 8 truck’s total fuel expenses, which translates to about $0.13 per mile. By minimizing energy loss caused by tire deformation during rotation, LRR tires improve efficiency. A 3% reduction in rolling resistance can save 1% in fuel consumption, boosting mileage by 0.05 miles per gallon. Over thousands of miles, these small gains add up.

Cyrille Roget, Science and Innovation Communications Director at Michelin, highlights the importance of tire choice:

"A tire’s fuel consumption represents one full tank in five. This is linked to the tyre rolling resistance. And it’s not insignificant, if you think about the amount of fuel we put in our tanks. So the right tyre can really help you save money."

The cost of fuel lost to rolling resistance can be as much as five times the tire’s purchase price. Real-world tests back this up, showing that specific steer tires and wide-base singles can save 8.15 gallons per 1,000 miles – a 7.04% improvement. For owner-operators driving 100,000 miles annually, this translates to more than 800 gallons of fuel saved.

Daryl Bear, lead engineer and chief operating officer at Mesilla Valley Transportation Solutions, emphasizes the ease of this upgrade:

"They’re already buying tires, so by simply changing a brand, they can improve fuel economy and save a tremendous amount of money."

LRR tires are often priced similarly to, or even less than, traditional tires, and advancements in technology mean they now offer comparable or superior mileage. To maximize their benefits, ensure proper tire inflation – just a 5 PSI drop can erase efficiency gains. Research from Continental shows that rolling resistance is distributed across axle positions: 15% on the steer axle, 42.5% on the drive axle, and 42.5% on the trailer axles. Prioritizing LRR tires on drive and trailer axles can yield the best results.

Install Aerodynamic Equipment

Pairing tire upgrades with aerodynamic modifications can amplify fuel savings. Drag accounts for up to 50% of a semi-truck’s energy use on highways. Tools like trailer side skirts (cutting fuel use by 4–7%) and roof fairings (improving efficiency by 3–5%) are highly effective. Combined, aerodynamic kits can reduce fuel consumption by 5-15%. For instance, cutting the drag coefficient by 10% can lower fuel use by 5-7%, while a 20% reduction can save 10-14%.

Barry Personett, Vice President of Product & Sales Engineering at Great Dane, explains the industry’s focus on proven solutions:

"Aerodynamic devices are added to our trailers to reduce drag and improve fuel efficiency. Devices are required to prove their ability to reduce fuel consumption through CARB and the EPA."

Side skirts streamline airflow under the trailer and around its components, while roof fairings help trucks hauling high-roof trailers by directing air more smoothly over the top. These adjustments reduce drag behind the cab and lighten the engine’s workload.

Aerodynamic improvements can be even more impactful in colder climates, where denser air increases drag by up to 20%. However, the effectiveness of these upgrades depends on your operation. For long-haul highway routes, side skirts and boat tails can deliver big savings. On the other hand, local fleets with frequent stops might not benefit enough to justify the investment. Tailoring aerodynamic upgrades to your specific needs ensures the best return on investment.

6. Cut Engine Idling Time

Idling can quietly drain your wallet. A diesel engine burns about 0.8 gallons of fuel per hour while idling. Over the course of a year, with an average of 1,000 idle hours, that adds up to 800 gallons of wasted fuel. At $3 per gallon, that’s $2,400 spent on fuel that could’ve stayed in your pocket.

Here’s the kicker: idling for just 10 seconds burns more fuel than restarting your engine. If you’re running 100,000 miles annually, cutting idle time by just 10% could save you 1% in fuel – around $500 to $700 a year. The solution? Leverage technology to minimize idle time and maximize savings.

Use Auxiliary Power Units (APUs)

Auxiliary Power Units (APUs) are a game-changer for cutting down idle time, especially during rest periods. They keep the cab comfortable and power essential systems without running the main engine. Even better, they use only about 25% of the fuel your truck engine would consume while idling.

Yes, there’s an upfront cost – APUs range from $2,000 to $8,000 per truck, with high-end models like the Thermo-King Tri-Pak priced around $10,000. But the savings can be worth it. For example, direct-fired heaters, another option, use just 5% of the fuel required to idle the main engine.

Consider this: A 120-truck fleet that installed Idle Smart systems cut engine idling by 43%, saving over $380 per truck each month. They also saw fewer breakdowns and reduced maintenance on aftertreatment systems. Another company with 40 trucks reported a 52% decrease in fuel consumption from reduced idling, slashing over 47,000 pounds of CO₂ emissions. These technologies even help fleets comply with anti-idling regulations, avoiding hefty fines.

Install Automatic Engine Shutdown Systems

Automatic Engine Idle Shutdown (AEIS) systems simplify idle management by automatically turning off the engine after a set period. This reduces fuel waste and prevents unnecessary wear on the engine during long stops.

Take the Kalmar Automatic Engine Stop System, for example. It can be programmed to shut down the engine after three to 30 minutes of idling. With a simple software upgrade, it integrates seamlessly with your vehicle, alerting operators through an in-cabin display. These systems ensure the engine runs only when absolutely necessary.

The cost of AEIS systems varies widely, from $100 to $10,000, depending on the model and features. They also provide flexibility by overriding factory idle limits, giving operators more control. Coupled with telematics systems, you can monitor idling patterns, coach drivers, and set clear expectations to further reduce idle time.

Of course, some idling is unavoidable for safety or cargo needs. But by eliminating unnecessary idling during breaks and stops, you’ll see real savings while keeping your operations smooth.

7. Add Fuel Additives and Monitoring Technology

Combining fuel additives with advanced monitoring technology can stretch every gallon further while giving you the tools to make smarter fuel decisions. Modern diesel engines encounter unique challenges that additives can address, while telematics systems provide real-time insights to improve performance and uncover savings.

Diesel Fuel Additives: A Practical Boost

Fuel additives are designed to tackle specific issues that can drive up costs. For example, ultra-low sulfur diesel (ULSD) lacks the lubricity of older fuels, leaving engines more prone to wear. Additionally, lower cetane levels and fuel system deposits can hurt combustion efficiency and overall engine performance.

"Using the right additive protects fuel systems and improves efficiency." – Deer Park Diesel

Products like Hot Shot’s Secret Everyday Diesel Treatment (EDT) can boost fuel economy by up to 7.3% and raise cetane levels by 7 points. Similarly, AMSOIL Diesel Injector Clean has shown fuel economy improvements of up to 8%. For owner-operators, these gains translate into meaningful fuel cost savings.

Choosing the right additive depends on your specific needs and operating conditions:

• Anti-gel additives: Ideal for temperatures below 30°F.
• Cetane boosters and injector cleaners: Enhance fuel economy and engine performance.
• Lubricity enhancers: Help protect older vehicles.

Power Service, for example, recommends Diesel Kleen +Cetane Boost (silver bottle) for temperatures above 30°F and Diesel Fuel Supplement +Cetane Boost (white bottle) for winter conditions below 30°F.

To maintain optimal performance, follow a regular schedule:

• Use EDT with every fuel fill-up.
• Apply Diesel Extreme every 6,000 miles.
• Use diesel injector cleaners every 3,000 to 10,000 kilometers.

Always consult your vehicle manufacturer’s guidelines and avoid overusing additives – more isn’t always better.

Telematics Systems: Real-Time Insights for Better Efficiency

While fuel additives improve combustion, telematics systems take optimization a step further by delivering real-time data. These systems combine GPS tracking with diagnostics to monitor fuel consumption, driver behavior, engine performance, and location. By promoting better driving habits and providing actionable insights, telematics can cut fuel expenses – which typically account for 24% of marginal costs – by as much as 20%. For someone spending $30,000 annually on fuel, even a 10-15% improvement can result in significant savings.

Tourmo AI’s Fuel & CO₂ solution showcases these benefits, improving fuel efficiency by up to 20%, reducing fuel costs, detecting potential fuel theft, and simplifying environmental reporting by up to 40%.

When selecting a telematics system, consider your specific needs:

• Basic plans: Typically $10 to $20 monthly per vehicle.
• Mid-tier plans: Include engine diagnostics and fuel monitoring for $25 to $40 per vehicle.
• Premium plans: Offer advanced analytics and integration features for $50 or more per vehicle, plus hardware costs ranging from $100 to $300 per device.

For refrigerated operations, opt for systems with customizable temperature thresholds and real-time monitoring. Ensure the system integrates seamlessly with your existing TMS and ELD systems for maximum efficiency. Features like driver scorecards, predictive maintenance, and geofencing can further enhance your investment.

"Fleet telematics puts you in the operational driver’s seat and enables more control over your fleet thanks to data-driven insights that lead to better decisions." – Solera
