How to track car gas mileage?


The economic crisis and the effects of the coronavirus epidemic are hitting the transport and logistics industry and all the companies that use cars, trucks, passenger vehicles and special vehicles in their work. The key to survival in this situation is to reduce fuel costs and increase efficiency at the lowest possible cost. In this article, we will explain in detail which solutions can help with this. By the way, I recommend paying attention to fuel MPG through

MPG Meaning: Everything You Need to Know

Controlling fuel consumption without satellite systems

Many car fleets still do without GLONASS/GPS monitoring. Let’s assume that fuel accounting and write-off are correct in the company and the problem of over consumption of fuel seems not to bother the driver. But can the company management claim to be in the possession of all the information? Probably not. Real control is when it is possible to compare as many different readings as possible and identify the causes of discrepancies.

For example, calculating fuel consumption according to the Ministry of Transport’s norms will not be objective, as these norms are extremely average and sometimes differ greatly from the actual readings of a particular vehicle. If the actual consumption is calculated on the basis of odometer data, the accuracy will also be «lame». Accuracy of these devices sometimes exceeds 15-20%, and drivers can «cheat» on mileage. If fuel receipts for petrol or diesel fuel are taken into account when writing off fuel, there is a risk that they are fake. And fuel card accounting does not always guarantee transparency, because drivers can collude with petrol station employees.

Satellite monitoring without fuel sensors

For basic satellite control, it is enough to install a professional GLONASS/GPS tracker, which sends information about vehicle movements, including coordinates, speed and mileage, to the monitoring system.

The mileage recorded by the trackers is much more reliable than the vehicle’s regular odometer readings. Therefore, satellite data helps to calculate fuel consumption more accurately and make objective write-offs. Also, by comparing the mileage from the monitoring system with the trip tickets, it is possible to find out whether the drivers are adding up kilometres.

Controlling fuel consumption using an in-house sensor via the CAN bus

What is a CAN bus?

It is an interface that allows the exchange of CAN-bus is an interface that allows the exchange of information between different sensors and electronic systems in the vehicle and also external devices within the framework of a unified CAN network (Controller Area Network). CAN-Bus is present in all modern vehicles.
