Discover the top dashboard reports to help track trends and reduce your fuel spend when costs are on the rise.

For many companies, fuel consumption and related costs are a top priority. Fuel remains one of the largest expenses for fleets, with fuel accounting for 60% of total fleet operating costs. In fact, fuel is often the number one expense they track.

As gas prices rise, there is even more pressure on managers to control costs while still maintaining operations and keeping customers happy. This is where technology can help. By connecting to telematics, fleets can clearly see where their dollars are going, and identify and limit wasteful behaviors.

If you are looking to get a quick understanding of how and when fuel is consumed and if fuel is being wasted, MyGeotab is a ready-source of detailed and historical information on fuel trends. Here are the top MyGeotab reports to help you increase fuel efficiency and manage fuel costs.

Fuel and EV Energy Usage report

The Fuel and EV Energy Usage report, found under the Engine & Maintenance section in MyGeotab, summarizes fuel economy, distance traveled and monthly fuel usage across a chosen time period. The report can be filtered by vehicle or time period.

This report helps fleet managers identify the fuel efficiency and performance across the whole fleet or specific vehicles. You can examine the fuel economy of your assets and determine the action needed to improve efficiency and slash costs through improving driver behavior or targeting maintenance.

Fill-Ups report

The MyGeotab Fill-Ups Report shows fuel fill ups that are detected from a vehicle's fuel level diagnostic measurements or from user imported fuel transactions. A fill-up event is defined as anytime fuel is added to the vehicle. The report will show you a brief summary, including total fuel added and total cost, for the time period you select.

This valuable fleet report can point you to unmatched fuel transactions that need further investigation. You can also use this telematics data to validate fuel transactions.

Green Fleet Dashboard

The Geotab Green Fleet Dashboard is a tool for monitoring your fleet’s performance in improving fuel economy and reducing emissions. Available for free on the Marketplace, the Green Fleet Dashboard allows you to monitor the fleet’s average fuel energy usage, cost, and resulting emissions on a total or economy basis. Having a holistic view of fuel usage provides excellent insight to inform fleet fuel policies and coaching on fuel efficient driving.

Benefits of the Green Fleet Dashboard:

  • View trends in average fuel and electric energy usage, cost and CO2 emissions

  • Benchmark your fleet’s fuel economy to other similar fleets

  • Monitor the performance of battery-powered electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV)

  • Track idling time, harsh driving events and charging exceptions

  • Establish ways of improving cost and emissions by analyzing idling history and patterns

More strategies for improving fuel efficiency

Having the right tools can go a long way to improving overall performance. To help your fleet optimize fuel consumption, consider implementing these strategies:

Compare fuel usage trends for bigger fuel wins

When targeting fuel usage patterns, it pays to look at the bigger picture. Fleets should be asking:

  • What have fuel consumption and idling trends looked like over the last three months?

  • What are the trends on aggressive driving and miles driven?

If idling, speeding and mileage are reduced, then fuel consumption should decrease as well. This way, reviewing trend reports can help track patterns and identify anomalies or coaching opportunities.

Heather Carlton, Geotab Associate Vice President, Reseller Sales, explains that addressing factors such as aggressive driving, speeding and idling is a worthwhile effort. “Monitoring fuel usage is a good barometer of other programs that you have in place,” says Carlton.

Cross-referencing different metrics can provide greater insight and doesn’t separate your data into silos. “It’s a great idea to put all your fuel-related reports side-by-side on the dashboard,” Carlton advises.

By watching these trend lines, fleets can also tell whether their programs are working, or need fine-tuning. If you see fuel usage staying flat or increasing, it is an indicator that it’s time to review and adjust the program.

Monitor your fleet’s miles driven statistics

Another important factor to consider is miles driven. Carlton recommends evaluating whether drivers are taking the most efficient routes, or if the fleet is dispatching the most efficient drivers to service calls. MyGeotab is ideal for managing miles driven as it provides full visibility into mileage, routes taken and drive time.

Optimizing routes and reducing miles driven can lead to more customer visits per day. “Helping businesses maximize their productivity, use that time on the road to make money instead of spending money — that’s what we want to achieve,” says Carlton.

How does Geotab capture fuel data?

Information is broadcast through the electronic control module (ECM) for some vehicles, while others require a request for data. In some cases, fuel must be calculated on our end using other diagnostics like mass airflow. This all depends on the protocol in place.

Engine protocol refers to the language “spoken” by the vehicle’s engine computer module. Protocol is dependent on the vehicle’s make, model and/or year.

The three main protocols used industry-wide which we support are:

  • J1708

  • J1939


In vehicles with different protocols, we look at each on a case-by-case basis and use debug data to identify how to capture the fuel data and correctly report it. The accuracy in which we record fuel varies between 0.001L to 0.5L, depending on the protocol and how the engine broadcasts this information. For most vehicles, we are able to pull different types of diagnostics like trip, idle fuel used, fuel level, water in fuel and more.

How do we match fuel card data?

To match a fuel transaction to a device, there must be at least one matching reference field from the below list:

  • VIN

  • Device serial number

  • License plate number

  • Device description

  • Device name

  • Comments

Fuel transactions that cannot be matched to the telematics data are highlighted in yellow.

Importing fuel card data into MyGeotab

MyGeotab accommodates any fuel transaction data, as long as it is in .csv or .xls file format. Fuel card importing is not tied to any specific manufacturer. Fuel transactions can be imported into your MyGeotab database via the Fuel Transaction Import Add-In or by using the API.

Ongoing developments in fuel usage tracking

Geotab is continuously working on fuel data output to optimize accuracy and support for vehicles. Currently, we are working on improvements that include:

  • Additional data to help support and develop calculations for non-petroleum vehicles when standard sources are not available (ethanol, diesel).

  • Routine firmware updates that contain fuel bug fixes and improved fuel calculations.

Future developments include:

  • Constant monitoring of fuel data from the Geotab GO device.

  • Continuous investigation of devices that fail to report fuel data so support can be added. Future requests are encouraged to help improve Geotab’s fuel support.

What’s next?

If you are looking for ways to cut costs, fuel consumption is one of the top areas to target. Geotab Regulatory, Pro and ProPlus users have access to some powerful features right in MyGeotab for reducing their fuel spend. Money saved on fuel can be redirected to more valuable business areas, such as product development, operations and human resources or training.

As Geotab leads the way in telematics, we strive to support as many vehicles as we can for all types of engine data. As we continuously keep testing, our vehicle support will increase and the data will continue to become more accurate. From the Analytics Lab to the EVSA, Geotab is working to lead the way in telematics support and experimentation.
