Trucks and commercial vehicles
Fuel saving for trucks
On a commercial vehicle, fuel is the largest cost per kilometre. CFSS is a fuel saving system for trucks that lowers diesel consumption in real duty cycles — without changing routes, payload or driving style.

How to reduce fuel consumption in a truck fleet
Truck fuel consumption depends on engine, load, terrain and driving style. Driver training and route planning help, but they hit a ceiling. CFSS works on the combustion process, so the fuel consumption reduction is delivered on every kilometre, whoever is behind the wheel.
Results are tracked in L/100 km using refuelled volume and distance from your fleet management system or vehicle CAN data.
- Long-haul — constant load, high annual mileage
- Distribution — frequent stops and variable duty cycle
- Municipal and special-purpose vehicles — body operation on top of driving
What a 7% fuel saving means in money
A truck consuming 33 L/100 km over 120,000 km a year burns roughly 39,600 litres of diesel. The guaranteed 7% is about 2,770 litres per vehicle per year — multiplied by every truck in the fleet.
The saving calculator on this page runs on your own figures, including a projection over the full 700,000 km service life of the unit.
Installation without taking trucks off the road
Certified technicians install the system during a planned service interval. No vehicle leaves service because of us and fleet availability stays unchanged.

FAQ
Questions we are asked most
How much fuel does a truck use per year?
It depends on the application: a long-haul truck covering 120,000 km at around 33 L/100 km burns close to 40,000 litres of diesel. The calculator on this page gives the exact figure for your vehicle.
Does it work on Euro 5 and Euro 6 engines?
Yes. Measurements have been carried out on both Euro 5 and Euro 6 vehicles, including the independent test at JKP GSP Belgrade.
Does installation affect the vehicle warranty?
The installation does not interfere mechanically with the powertrain and is performed by a certified technician. We review the details for your vehicle type before installation.
Let us test CFSS on your trucks
We propose a reference measurement on part of the fleet. If the measured fuel saving does not match the guarantee, there is no reason to continue.
