Fuel saving for transport companies and fleets
For a transport company, fuel is not a line item — it is the margin. CFSS delivers fleet fuel savings across every vehicle class in operation, with results documented per vehicle so finance and operations read the same numbers.

How transport fuel savings scale across a fleet
A single truck saving 2,700 litres a year is a useful number. A hundred trucks doing the same is a budget decision. CFSS is deployed fleet-wide in stages, so the fuel consumption reduction measured on the pilot group defines the business case for the rest.
Reporting follows your existing structure — per vehicle, per depot, per contract — using refuelling records, odometer readings and engine hours you already collect.
- Pilot group with a documented baseline
- Staged rollout during regular maintenance windows
- Consolidated fleet fuel efficiency report per period
Lower fuel costs without touching operations
Nothing changes in dispatching, routing or scheduling. We make dispatch easier rather than harder: no additional driver procedures, no changes to the transport plan, and no vehicle removed from service outside its planned interval.
What the verification looks like
Independent testing at JKP GSP Belgrade recorded 9.14% lower fuel consumption on a bus fleet, and Serbia Cargo measured a 20.6% reduction in rail traction. Both reports are published in full, signed by the client.

Okvirna projekcija zasnovana na garantovanom minimalnom povećanju efikasnosti od 7% na tečnim gorivima. Ugovorne vrednosti potvrđuju se dokumentovanim referentnim merenjem i nadziranim pilot projektom na vašoj floti.
FAQ
Questions we are asked most
How do we prove the saving to management?
With a before-and-after comparison of the same routes and duty cycles, based on your own fuel and mileage data — not on our estimates.
Can we start with only part of the fleet?
Yes, and we recommend it. A pilot group produces the measured business case for the full rollout.
Which vehicle types are covered?
Long-haul and distribution trucks, buses, municipal vehicles, special-purpose bodies and diesel gensets used on site.
Build the business case on your own fleet data
Send us fuel consumption and mileage for a representative group of vehicles and we will structure the pilot measurement around it.
