How to review fuel apportionment

Last updated 19 October 2026

Overview

Fuel apportionment estimates how much fuel each GPS-tracked asset used for driving and idling on public roads, driving and idling off public roads, and auxiliary equipment. The estimate combines recorded activity with the fuel consumption rates configured for the asset. It is not a list of actual fuel purchases.

Steps

  1. Open GPS Apportionment and select the reporting period. The Fuel Apportioned card shows the fleet total and the split between on-public roads, off-public roads and auxiliary equipment.

  2. Select View individual vehicle details, then Tables and Fuel Apportionment. The table shows a row per vehicle with fuel type, estimated litres for each activity, total litres, percentages and the driving, idling and auxiliary fuel rates. Scroll horizontally to inspect all columns.

  3. Compare the results with the asset's operating activity and fuel settings. To review individual journeys, switch to Explorer, select a vehicle and open a trip.

If a figure looks unexpected

  • Confirm the period and the vehicle's telematics connection.
  • Check its driving, idling and auxiliary fuel consumption rates in the Register.
  • Review GPS validation for flagged trips.
