How to improve fleet fuel efficiency & lower spend
Fuel is one of the largest fleet operating expenses. While fleet managers can’t control the price at the pump, they can influence how much fuel their vehicles use—and where it may be going to waste.
Some sources of fuel waste are easy to spot. Others can build quietly across the operation: unnecessary miles, repeated speeding, engines excessively idling, or fuel purchases that don’t match fleet activity. Individually, these issues may seem small. But across a fleet, they add up.
Finding opportunities to reduce fuel waste starts with visibility. Fleet fuel management is the process of tracking, understanding and improving how fuel is used across a fleet—from driver behavior and routing to idling, maintenance and fuel purchasing. Fleet fuel management systems offer a clearer picture of what’s truly driving consumption and costs.
In this guide, you’ll see that with that clarity, fleet managers can make more informed decisions about where to focus, what actions to take and how to improve fuel efficiency over time.
1. How fleets can reduce fuel costs and consumption
Fleet fuel waste can be hard to fix when you can’t see where it’s happening. Fleet fuel management software uses telematics and other fleet data to help surface patterns in consumption and spending, so you can focus your efforts where they’re most likely to make a difference.
AREA TO REVIEW | WHAT TO LOOK FOR |
| Driving behavior | Patterns such as speeding, rapid acceleration or hard braking |
| Unnecessary idling | Engines running when the vehicle or equipment doesn’t require it |
| Vehicle maintenance | Tire condition and pressure, fuel filters, axle alignment and other factors that can affect fuel economy |
| Navigation and routing | Unnecessary mileage, backtracking and inefficient routes |
| Fuel purchasing | Purchases that don’t align with vehicle location, activity or tank capacity |
Rather than assuming every issue deserves equal attention, look for recurring patterns that stand out from the rest of the fleet. Those signals can help you decide where to investigate—and act—first.
Address fuel-wasting driving habits
Speeding, rapid acceleration and hard braking can all work against fleet fuel efficiency. The question is: where are those behaviors happening most often?
Fleet fuel management solutions can help surface recurring patterns by driver or vehicle, giving you something concrete to act on. From there, targeted coaching, in-cab alerts, driver scorecards and positive reinforcement can help turn those insights into more fuel-efficient habits.
Keep vehicles maintained for better fuel economy
When fleet fuel consumption starts creeping up, the vehicle may be telling you something.
Proper tire pressure, tire wear, fuel filters, axle alignment and motor oil can all affect fuel economy. Looking at vehicle condition alongside fuel performance can help you determine whether maintenance may be contributing.
Look beyond fuel consumption
Fuel theft, unauthorized purchases and other forms of fuel slippage can also contribute to waste.
Connecting fuel-card transactions with telematics data can help fleets compare purchases with actual vehicle activity. For example, managers can flag transactions when the assigned vehicle wasn't at the fueling location or when the amount purchased exceeds the vehicle's tank capacity.
Together, these insights can help fleet managers build a clearer picture of where fuel is being used. And once you know where fuel may be going to waste, a fuel savings calculator can help you explore what greater fuel efficiency could mean for your fleet.
2. Route planning
Every unnecessary mile uses fuel. In fact, just 5 unnecessary miles per day across a 20-vehicle fleet can add up to more than 25,000 wasted miles a year—bringing additional fuel costs, vehicle wear and labor time with them.
Better route planning can help fleets spot and reduce wasted mileage caused by backtracking, inefficient stop sequences, traffic or changing schedules. By planning around real-world conditions, fleet managers can make each mile work harder and reduce the fuel spent.
Plan for more than the shortest distance
The shortest route on a map isn't always the most efficient for a working fleet. Route planning considers the real-world factors that affect how vehicles move throughout the day, including traffic congestion, delivery windows, required stops, vehicle type and capacity, compliant truck routes and driver availability.
As conditions change, near real-time adjustments can help drivers navigate around congestion, construction and roadway incidents that could otherwise add mileage or leave vehicles sitting in traffic.
3. Getting engine idling under control
Engine idling can use as much as one-quarter to one-half gallon of fuel per hour. Not all fleet idling is wasteful, so reducing it starts with knowing the difference. Fleet managers can use idling data to identify patterns, set clear thresholds and monitor progress over time.
With greater visibility into when and where idling occurs, fleet managers can identify opportunities to reduce unnecessary engine use and help keep fuel costs in check.
Separate productive idling from unnecessary idling
Some vehicles may need to idle to power equipment through a power take-off (PTO), but the goal is to distinguish that productive use from avoidable behaviors.
Start by looking at when, where and how long vehicles are idling, and what the vehicle is doing at the time. Once you understand your fleet’s baseline, establish expectations around acceptable and excessive idling.
From there, alerts provide near real-time notification when a vehicle exceeds those limits, making it easier to address patterns before they become routine. The right threshold may vary by vehicle and operation, which why alerts are customizable to fit company needs.
Check whether your idling strategy is working
Setting a policy isn't the finish line. Detailed reports and dashboard metrics can help show whether idle time actually decreases after thresholds are put in place.
Reviewing that information daily, weekly or monthly can help managers identify persistent problem areas, track changes and adjust their approach as needed.
4. Coaching, incentives and vehicle considerations
Lasting fuel savings depend on what happens behind the wheel. Fleet managers can use driving data to identify recurring behaviors, focus coaching where it can have the greatest impact and recognize drivers who improve.
Turn driver data into clear direction
One hard brake or long idle may not tell you much. The same behavior happening day after day is a different story.
Driver scorecards can help you find patterns across hard braking, rapid acceleration and idling. Idling alerts, detailed reports and dashboard metrics can help managers identify which drivers—or habits—consistently stand out.
That gives managers a more focused coaching conversation: What keeps happening, why is it happening and what specific behavior should change?
| DATA | ACTION |
| A one-time event | Look for more context before intervening |
| A recurring behavior | Targeted coaching around that specific habit |
| Improvement over time | Recognition or positive reinforcement |
| Little or no improvement | Revisit the goal, coaching or expectations |
| Consistent strong performance | Use it as an example of what good looks like |
Turn fuel data into driver action
"Use less fuel" is difficult for a driver to act on. Specific behavior is much easier. Recognition, leaderboards and incentive programs help reinforce the behaviors you want to see more often. According to the U.S. Department of Energy, drivers who receive feedback on their driving habits can improve fuel economy by an average of 3%—and by as much as 10% when fuel savings is the explicit goal.
Over time, that combination of visibility, coaching and recognition can help make fuel efficiency part of how the fleet operates.
5. Simplifying fuel tax tracking and reporting
For fleets operating across multiple IFTA jurisdictions, managing fuel costs also comes with an administrative burden: tracking mileage, fuel purchases and fuel taxes by jurisdiction. Customers can track location data manually to compile their own IFTA reports or integrate GPS data with a third-party provider to streamline report creation.
Simplify mileage tracking
For qualifying fleets operating across multiple IFTA jurisdictions, reporting requires tracking miles traveled, fuel purchased and fuel tax paid by jurisdiction.
The question is how much of that information your team is still gathering and calculating by hand.
GPS-powered journey reports can help track distance traveled by state, while fuel-card integrations can connect fuel-purchase and location information with fleet data. Having more of the information readily available can reduce the time spent gathering records from multiple sources.
| REPORTING TASKS | HOW TECHNOLOGY CAN HELP |
| Calculating mileage by jurisdiction | Tracking distance traveled by state |
| Managing fuel receipts across locations | Integrating fuel-purchase data |
| Organizing records for potential audits | Centralizing records and simplifying data exports |
Connect mileage with fuel-purchase data
Mileage is only one part of the IFTA equation. Fleets also need accurate records of where fuel was purchased.
Connecting mileage and fuel-purchase data can create a more consistent foundation for quarterly reporting. Fleets can use this information to manually compile their IFTA reports or connect with a third-party provider to further streamline the reporting process.
The goal is to make the information needed for IFTA reporting easier to track and manage—helping reduce administrative effort and support more consistent recordkeeping.
6. Next steps: finding fuel-saving opportunities
Reducing fleet fuel costs isn't about finding one big fix. It’s about identifying where fuel is being wasted and taking action across the areas you can influence.
Find your next fuel-saving opportunity
1. Measure
Establish what normal fuel use and fleet activity look like today.
2. Identify
Look for patterns, outliers or unnecessary activity that could be driving fuel costs.
3. Act
Find your opportunity: whether it's routing, driver behavior, idling, maintenance or fuel purchasing.
4. Re-measure
Check whether the change made a difference, then identify the next opportunity.
Where should your fleet focus first?
Use these questions to identify where your biggest opportunities may be:
- Are vehicles regularly traveling unnecessary miles? Take a closer look at past behaviors.
- Are speeding or other fuel-wasting behaviors showing up consistently? Focus on driver visibility and coaching.
- Are vehicles idling longer than necessary? Establish a baseline, set expectations and monitor improvement.
- Could vehicle condition be affecting fuel economy? Review maintenance practices and recurring issues.
- Do fuel purchases match vehicle activity? Look for unusual transactions or potential fuel slippage.
- Is fuel reporting taking more time than it should? Explore ways to simplify mileage and purchasing data collection or integrate with a third-party IFTA reporting provider.
Start where the data points to the greatest opportunity, measure the results and keep looking for the next improvement.
