Fuel Waste Benchmark by Fleet Type

Author: FleetOpsClub Research Team Published: April 5, 2026

The single most useful number in fuel waste is the idle burn rate, because everything else follows from it.

Putting a dollar figure on it

Idle gallons only become a budget line when you price them. US on-highway diesel retail averages, from EIA:

The August 2026 figure is an event-driven spike rather than a trend, so plan against the 2025 annual average unless you are budgeting for this quarter specifically.

At $3.660 a gallon, the DOE idle figures produce:

Argonne's own framing treats roughly 2,000 idle hours a year as a high idler and about 1,000 as a low one. A fleet of twenty trucks sitting at the high-idle end is burning something in the region of $100,000 a year in fuel that moves nothing.

Fuel waste matters in proportion to what fuel costs, and ATRI publishes the only reconciled per-mile breakdown of that.

*Source: ATRI, Analysis of the Operational Costs of Trucking: 2026 Update, July 2026, data year 2025.*

Fuel is 20.6% of marginal cost per mile — second only to driver wages. Total costs rose 3.4% year over year; excluding fuel they rose 4.2% to $1.854, which means fuel was the one line that held roughly flat in 2025 while everything else climbed.

The small-fleet penalty is measurable

ATRI's fleet-size analysis found truckload carriers operating more than 1,000 trucks pay **$0.088 per mile less for fuel** than carriers running fewer than five. Over 100,000 miles that is $8,800 a year, per truck, purely on purchasing scale.

Small fleets cannot buy their way to parity on price. What they can do is remove waste, which is why idle reduction is disproportionately valuable at the small end — it is the only fuel lever that does not require volume.

An honest note on what this report does not contain. A genuine "waste by fleet type" table — refuse versus long-haul versus last-mile — would require telematics data across a representative sample of fleets in each segment. That data is held by telematics vendors, is not published, and where vendors do publish adoption or efficiency figures they are marketing surveys rather than neutral measurement.

We have not invented that table. What is above is what can be sourced: a per-hour burn rate from DOE, a fuel price series from EIA, and a per-mile cost structure from ATRI. Those three are enough to calculate your own waste figure from your own idle hours, which is more useful than a segment average you cannot verify.

This report benchmarks fuel waste across the main operating models common in commercial fleets:

• local delivery
• field service
• regional and long-haul trucking
• mixed municipal and utility fleets
• construction and vocational fleets

It focuses on the practical drivers of waste:

• idle time
• routing inefficiency
• speeding and driving behavior
• vehicle condition
• jobsite or equipment-related burn
• fraud or unauthorized fuel activity

This report is built by reading vendors' own published pricing and product documentation and recording what each one states, together with the date it was checked. FleetOpsClub holds no proprietary pricing dataset and runs no buyer survey. Where a figure appears here it is quoted from a named public source; where a vendor publishes nothing, the report says so rather than estimating. Vendor pricing changes without notice, so treat any figure as accurate to its stated check date and confirm before budgeting.

Public sources used for context include:

• EPA SmartWay material on freight efficiency and fuel performance (EPA SmartWay)
• ATRI's work on operating costs in trucking, which helps explain why fuel remains one of the most heavily managed line items in transport operations (ATRI Operational Costs of Trucking)
• DOE and AFDC guidance on idle reduction and fuel-saving practices (Department of Energy idle reduction)

This benchmark is not a guaranteed financial forecast. It is a market and operating guide to help fleets compare waste patterns more realistically.

Fuel waste is often discussed as if it were a simple MPG problem. That view is too narrow. MPG can signal a problem, but it rarely explains the cause by itself. Two fleets can report the same fuel performance and still be wasting fuel for completely different reasons.

One fleet may have heavy urban stop-and-go driving and too much idle time. Another may have weak route sequencing. Another may have vehicle maintenance issues. Another may simply be running a fleet type where usage is naturally heavier because of jobsite load, PTO operation, or seasonal operating conditions.

The most useful benchmark is not one number. It is a structure that separates:

1. behavior-related waste
2. planning-related waste
3. equipment- or operating-model-related waste

That structure helps teams focus on the right fix instead of applying the same fuel policy to every part of the operation.

Local delivery fleets

Delivery fleets usually waste fuel through route density problems, heavy idle time, repeated acceleration, and stop-sequencing issues. Driver behavior matters, but route design often matters just as much. The best benchmark for these fleets is not only MPG. It is fuel burn per route, per stop cluster, and per shift pattern.

Field service fleets

Service fleets often lose fuel through a mix of idle time, technician routing inefficiency, and vehicles being used as mobile workspaces. A clean benchmark here separates windshield time from jobsite time. That makes it easier to see whether waste is tied to dispatch, driver habits, or the service model itself.

Trucking fleets

Trucking fleets usually track fuel closely, but waste can still come from long idle events, detention, speeding, route choice, equipment setup, or maintenance conditions like tire pressure and engine health. The benchmark should focus on cost and consumption by lane, vehicle, and driver pattern instead of looking at one fleetwide average.

Municipal and utility fleets

These fleets can have structurally higher fuel burn because of PTO usage, all-weather operation, emergency response patterns, and equipment-linked duty cycles. The main benchmark question is not whether the fuel number is high in the abstract. It is whether the burn profile matches the actual work being performed.

Construction and vocational fleets

Construction and vocational fleets often have the widest gap between normal fuel burn and wasteful fuel burn. Jobsite idling, off-road operation, heavy load conditions, and seasonal shifts all matter. The most useful benchmark here is role-specific rather than fleetwide.

1. Idle time

Idle time is one of the easiest waste sources to find and one of the easiest to misread. Some idle is necessary. Some is pure waste. Fleets improve faster when they separate those two.

2. Route and dispatch inefficiency

Poor route order, excess windshield time, avoidable return trips, and weak stop clustering can quietly drive fuel waste even when driver behavior looks acceptable.

3. Driver behavior

Aggressive acceleration, speeding, excessive warm-ups, and inconsistent shutdown habits still matter. But they should be benchmarked with route and equipment context so the fleet is not coaching the wrong problem.

4. Vehicle condition and fuel controls

Maintenance quality, tire condition, engine health, and fuel-card control all affect waste. Software becomes much more useful when the team can see fuel spend, telematics behavior, and maintenance exceptions together.

The strongest fuel benchmark systems let managers connect fuel to operations, not just to expense totals. Good visibility usually includes:

• fuel use by vehicle and driver
• idle and route context
• exception alerts for unusual consumption
• integration with fuel-card or transaction data
• maintenance visibility that explains efficiency changes
• location-aware trend analysis

That is what allows the fleet to identify whether the problem is fraud, poor routing, driving behavior, maintenance, or a vehicle role that needs a different benchmark.

The first common mistake is holding the whole fleet to one generic MPG target. The second is looking at fuel spend without route and duty-cycle context. The third is using telematics or fuel-card data without linking it to maintenance and operational decisions.

Fuel waste reduction works best when teams use a tighter feedback loop:

• spot the pattern
• identify the likely cause
• adjust behavior, routing, or maintenance
• verify that the change held

Without that loop, fuel reporting becomes passive. The fleet sees the problem, but does not manage it well enough to change it.

Fuel waste should be benchmarked by fleet type, route pattern, and operating model. Buyers evaluating fuel-management or telematics software should ask:

1. Can this system separate route-driven waste from behavior-driven waste?
2. Can it connect fuel data to idle, routing, maintenance, and transaction controls?
3. Can managers act on the data quickly enough to change the outcome?

Those are better buying questions than simply asking who shows the most fuel reports.
