Turn small tanks into measurable volume.
Passenger cars, service vans and light fleets become a serious case when consumption is measured across the whole population.

Light-duty fuel is fragmented, but the volume is enormous. NTROPYX separates petrol and diesel profiles so fleets see real litres, refill intervals and net operating cost.
Market exposed7.44 L/100 km
Recovery signal12% target
Proof contextPetrol + diesel cohorts
Treat petrol and diesel separately.
NTROPYX communication stays disciplined: each fuel profile is modelled by consumption, distance and operating use.
Show cost per 100 km before contact.
The visitor sees the business case in familiar fleet language: litres, refill interval, net cost and scalable recovery.
Why NTROPYX here
Built for light-duty procurement.
Immediate message: fuel efficiency, cleaner combustion, lower waste and a commercial path sized to the sector.
- The page keeps the 7.44 L/100 km real-world consumption evidence.
- NTROPYX is framed as a combustion catalyst, not a detergent or octane booster.
- Commercial route: clean cohort, annual fuel volume, documented dosage and reporting boundaries.
§ 03 · Consumption reality
Europe measures the gap: 7.44 L/100 km real-world for petrol + diesel cars.
European Commission OBFCM data for 2021-registered cars reports real-world fuel use of 7.89 L/100 km for petrol and 6.88 L/100 km for diesel. Combined petrol + diesel: 7.44 L/100 km, with a 21.2% average gap versus WLTP. Switzerland adds a dense installed base: about 4.76 million passenger cars, still mainly petrol and diesel, with average annual mileage around 12 500 km.
