Fuel monitoring with CAN bus and OBD vehicle data

After wages, fuel is usually the biggest running cost, and without data you're guessing. A tracker that reads the vehicle's CAN bus or OBD port reports the real fuel level, consumption and odometer, not an estimate. Then you can see which vehicles, routes and habits cost the most.

Real data instead of estimates

On trucks, the FMC650 reads fuel level, fuel used, the real odometer and engine data from the CAN or FMS interface. On cars and vans, the FMC003 plugs into the OBD port and reads whatever the vehicle makes available there. That varies by make and model.

Find the waste

Set fuel against idling time, speed and route history and you start to see where it goes. Often it's engines left running at drops, or a heavy right foot. Sometimes the route is just longer than it needs to be. The fuel reports let you compare like for like.

Recommended hardware

Which tracker to choose

Shop these trackers →
FMC150
Has its own CAN reader and works in cars, vans, trucks and buses. You get dashboard fuel level, fuel used and distance where the vehicle provides them. Needs a professional fit.
FMC250
Reads CAN like the FMC150, but in an IP67 case for vehicles and machines that work in wet or dusty conditions.
FMM003
Reads the OEM fuel level and odometer over OBD on supported vehicles. The SIM must support LTE-M or NB-IoT.
FMC125
Has RS232 and RS485 for digital fuel-level probes that measure the tank directly. CAN data needs an optional Teltonika adapter.
FMC230
Two impulse inputs for fuel flow meters, and it takes analogue level sensors too. CAN data needs an optional Teltonika adapter.
FMC130
Gets fuel level and odometer through an LV-CAN200 or ALL-CAN300 adapter, or a Bluetooth OBDII dongle (not included). It also takes an analogue fuel sender.
FMB125
2G only. Fine for a short fuel-probe project that ends before UK 2G closes from 2029. For anything longer, choose the FMC125.
ECAN02
Lets a Teltonika CAN tracker such as the FMC150 or FMC650 read the CAN bus without contact. What data you get depends on the vehicle.

Questions fleets ask

Does every vehicle report fuel level?

No. Trucks with an FMS interface generally do. Cars and vans on OBD depend on what the manufacturer makes available, so check your models with us first.

Is CAN data accurate enough for fuel reports?

For reports, yes. CAN data comes from the vehicle itself, so it's far better than estimating from distance travelled. If you want to catch fuel theft at the tank, you may still need a dedicated fuel sensor.
