Fuel is only manageable when each gallon is tied to a specific vehicle or machine. This guide covers the data to collect, the reports worth running, and where IFTA fits.
The foundation of fuel management is one record per fill: the date, the unit that received the fuel, the product, and the gallons. With those four items you can answer most questions about where fuel went.
Add the odometer reading for road vehicles and the hour-meter reading for machines. Without them, you can see how much a unit used, but not whether that was a lot for the work it did.
Standardize unit numbers early. A vehicle called Truck 14 in one system and T-14 in another will have its history split in two.
Raw gallons are hard to compare across a mixed fleet. Efficiency measures normalize the numbers.
Pick the measure that fits each unit type:
Report on the unit, but also on the driver or operator where you have the data, because the same machine can burn very different amounts depending on how it is run.
| Unit type | Primary measure | Data needed per fill |
|---|---|---|
| Trucks and vans | Miles per gallon | Gallons, odometer |
| Excavators, loaders, compressors | Gallons per hour | Gallons, hour meter |
| Generators | Gallons per hour at load | Gallons, hour meter, load notes |
| Mixed-use units | Gallons per job | Gallons, job code |
A baseline is a unit's own normal. Collect a few weeks of clean data and note the typical range for that machine doing that kind of work. Then watch for departures from it.
Useful exception reports include units with fuel use well above their baseline, fills larger than the tank capacity, fills with no matching odometer or hour reading, and fuel logged to units that were not running. A flagged item is a question to ask, not an accusation. Often the cause is a wrong unit number, a leak or a maintenance issue.
Tell a legitimate change from a problem. Seasonal work, a heavier route or new attachments change what normal looks like. When you know the reason, update the baseline instead of ignoring the flag.
Review exceptions quickly, because a flag from three weeks ago is hard to investigate.
Fuel is a real cost of every job, and it is easy to bury in overhead. If each fill carries a job, department or cost center code, accounting can charge fuel back to the work that consumed it. That makes job estimates more honest.
Consistency matters more than sophistication. A coding scheme that every fueling operator can use correctly is better than a detailed one that gets ignored.
Include DEF in the same records for diesel units that use it.
The International Fuel Tax Agreement is a fuel tax reporting system for motor carriers operating across state or provincial lines. It applies to qualified motor vehicles: those with two axles and a gross or registered weight over 26,000 pounds, those with three or more axles regardless of weight, and vehicles used in a combination whose combined weight exceeds 26,000 pounds. Light-duty trucks and passenger vehicles are generally outside it.
Qualified carriers file a report each quarter showing the fuel purchased and consumed and the miles driven in each jurisdiction. Under the usual schedule, reports are due April 30, July 31, October 31 and January 31. Carriers must keep supporting records for at least four years, including fuel receipts and trip or mileage records.
IFTA covers road vehicles. Off-road equipment and generators are not part of it. How fuel bought in bulk and dispensed from a yard tank is documented for IFTA is a detail to confirm with your base jurisdiction or tax preparer. Rules differ in the details, so rely on your base jurisdiction for authoritative answers.
Even for vehicles outside IFTA, state fuel tax rules, registration and credits can apply, and they vary by state. A tax professional can explain which ones apply to your fleet.
Keep IFTA records separate from your internal fuel reports, so each can be produced on request without confusion.
A monthly report does not need to be elaborate. The goal is to answer a few questions the same way every month, so trends stand out.
Share the report with the people who can act on it, such as the shop foreman, the dispatcher and whoever approves budgets. A report no one reads changes nothing.
A supplier's delivery record gives you the date, product and gallons for every fill, often unit by unit. If those records arrive in a form your office can read, they can stand in for manual fuel logs. Ask what format they come in and whether unit identifiers can be included.
Pair delivery records with your own odometer and hour-meter readings. That combination gives you complete per-unit reporting without drivers keeping receipts. For how fueling in the yard is arranged, see fleet fueling, and for the card comparison, mobile fuel delivery versus fuel cards.
Capture data at the moment of fueling. Entry from memory a week later is where unit numbers and gallons go wrong.
Reconcile monthly. Total gallons delivered should be close to total gallons recorded as used, adjusted for the change in tank inventory.
Date, unit, product and gallons. Add odometer or hour-meter readings to make the data useful for efficiency.
Generally no. IFTA applies to qualified motor vehicles, which are defined by weight and axle count. Confirm with your base jurisdiction.
No. IFTA concerns motor vehicles operating on public highways across jurisdictions.
Weekly is common for active fleets, and monthly can work for small ones. Choose a cadence your team will actually keep.
