Fuel and energy usage reports
Fuel and energy reports help you find cost savings in your fleet by identifying usage patterns and validating fill-up and charging events.
Tracking your fuel and energy usage helps you monitor where and when your vehicles are refueling during the day. You can use reports in MyGeotab to monitor your fuel efficiency, validate conventional fuel fill-ups, and monitor your electric vehicle's charging patterns.
Fuel and EV Energy Usage
Use the Fuel and EV Energy Usage feature to understand how the overall energy and driving efficiency of your fleet changes over time.
The Fuel and EV Energy Usage feature tracks the energy and fuel usage of your assets. This helps you identify the most and least efficient assets in your fleet in order to target low performers to save costs. The feature supports both fuel usage (L/100km) for conventional vehicles and energy usage (kWh/100km) for electric vehicles (EVs).
The feature displays your assets in a list with the following data:
Fuel/Electric energy economy: Indicates the efficiency by converting the amount of energy used into L/km.
Fuel used: Indicates the amount of fuel used.
Energy used: Indicates the amount of electric energy used.
Date: Indicates the date period for the search.
Distance: Indicates the total distance driven.
How fuel usage is calculated
Fuel usage is calculated using a combination of engine-reported fuel data, imported fuel card data, and GPS-calculated travel distance. The system calculates the fuel used during a trip by querying the Device Total Fuel Used metric from the engine. If imported fuel transaction data is available, it is also included in the calculation. Fuel economy is reported as the amount of fuel used over the distance traveled with the given fuel (in mpg or L/100 km).

Fill-Ups
The Detected Fill-Ups feature tracks stops associated with fuel level increases throughout your fleet.
A fill-up event is identified every time fuel is added to an asset. Viewing fill-up events in sum can help you identify inconsistencies and potential cost saving opportunities for your fleet.
Fill-up events are detected from the vehicles' telematics data, specifically changes in the fuel level reported by the engine. Importing fuel transactions is not required; however, imported transactions add cost and product type information to matched events.
The Detected Fill-Ups feature shows the following information for each asset:
-
The date of the fill-up event
-
The address where the event occurred
-
The device associated with the asset
-
The driver associated with the asset at the time of the fill-up
-
The fuel economy, calculated between the previous fill-up and the most recent fill-up
-
The volume of fuel added during the event
-
The odometer reading at the time of the fill-up
If there is a matching fuel transaction record for the event, the cost of the fill up and the product type are also indicated.
If some fill-up rows show no cost or product type, the system detected the fill-up from engine data but could not match it to an imported fuel transaction record. Only fill-ups matched to a fuel transaction display cost and product type.
Rules and exceptions cannot be created based on fill-up events at this time.
Troubleshooting missing fill-ups
If a vehicle was filled up but the event does not appear on the Fill-Ups page, consider the following:
-
The vehicle may not support the Fuel level diagnostic. Check the Engine Measurements report (Maintenance > Measurements) to confirm.
-
The selected date range might not include the time at which the fill-up occurred.
-
The detection algorithm requires a window of driving data to confirm a fill-up. The vehicle may need to be driven for a longer period before the event appears.

Fill-Up Validation
MyGeotab flags fill-up events when fuel transaction details don't match data from your GO device.
Imported fuel transactions are checked using data from your devices. If a fill-up event fails to meet the validation criteria, its row in the Detected Fill-Ups report shows a yellow warning icon. Hovering your cursor over the icon displays the reason why the system flagged the fill up.
When viewing details for a flagged fill-up, the details page shows rows marked in yellow where the fuel transaction details don't match the data from your GO device. This allows you to double check the provided details and determine your next steps.
Troubleshooting fuel usage calculations
If fuel usage appears inaccurate or is not being calculated, the vehicle may not support the required engine diagnostic.
If fuel usage appears inaccurate or is not being calculated, the vehicle may not support the Total fuel used (since telematics device install) diagnostic. Check the Engine Measurements report (Maintenance > Measurements) to see if the vehicle supports the diagnostic. Not all engine computers provide the detailed information needed to calculate all fuel consumption and fill-ups.
The tables below show what each report supports:
Fuel Usage Report
| Report will show | Quantity / Consumption |
|---|---|
| Vehicle diagnostic: Total fuel used | True |
| Vehicle diagnostic: Fuel level | False |
| If fuel transactions are imported | True |
Fill-Ups Report
| Report will show | Time, Location, Odometer | Amount, Consumption | Cost |
|---|---|---|---|
| Vehicle diagnostic: Total Fuel Used | False | True* | False |
| Vehicle diagnostic: Fuel Level | True | False | False |
| If fuel transactions are imported | True | True | True |
*Fuel Level or Transaction must also be present
Frequently Asked Questions (about Fuel Usage)
add a short desc here
To better understand the Fuel Usage and Fill Ups feature, we have put together some scenarios on how fuel usage is calculated, and how the data can help you get the most out of your fuel transactions.
What data must be included in the Fuel Transaction Import Add-In?
Fuel card data must include the following data points:
- A UTC date/time of the transaction;
- Coordinates (latitude, longitude);
- A vehicle identifier that matches at least one of the following telematics device fields: VIN device, serial number, license plate description, comments
- Volume (Liters)
- Cost
- ISO Currency Code
Is there API access to matched fill-ups?
Currently, the API call “FillUp” in the Telematics Provider SDK now provides access to engine fill-ups, fuel transaction fill-ups, or a combined (matched) fill-up.
Do fuel usage and fill-ups reports have any known limitations?
The fuel usage and fill-up reports have the following limitations that may impact the accuracy or detail of reported items.
- Fuel reports may not support certain vehicle types. For more information, please contact your authorized Reseller.
- Fuel use during idling is not included as a separate item in the fuel usage report.
- Use of Personal Mode impacts the detail in fill-ups report — fill-ups during a private trip are grouped together.
- Fill-ups report may not account for Small/Partial fill-ups since the fuel level change is not noticeable.
- Location of the fill-up may be inaccurate. The fill-ups report is not intended for IFTA purposes.
- Fill-ups reports may be inaccurate in rare scenarios. For example, a significant change in elevation (i.e. the vehicle tilts) or a significant change in speed may cause the fuel to slosh around.
