What the bench measured.

15.2% less fuel per kWh on the Scania DC13 road engine.¹
Power up 17.5% and 18.0%. Exhaust 20 to 32 °C cooler under load.^1,2
One Dose for passenger cars: 40–60 L per syringe.
One litre treats 2,000 to 50,000 litres, by strength.
Dose at the point of fill. No engine modification.
Tested by a CNAS L23122 accredited laboratory, March 2026.³

One bottle. Four strengths.

The 1 litre bottle. The ratio on the label is the volume of fuel one bottle treats.
The dosing chamber. Two caps and a graduated chamber marked 20, 30 and 40 ml.
The label. Made in Switzerland, with the fuel icons and the laboratory marks.
The ratio. Printed in the corner of every label, here 1 L : 50'000 L.
One Dose. The syringe is graduated to 5 mL; one dose is 3 mL. The sachet is Swiss made, with the CMA, ilac‑MRA and CNAS marks.

1 L : 10 000 L

Measured to the gram.

Two engines on accredited test benches, four campaigns each, with the fuel weighed rather than metered. The products of incomplete combustion fell the furthest: carbon monoxide, hydrocarbons, particulates and smoke, down 44.8% to 81.7%.

15.2% less fuel per kilowatt‑hour on the Scania DC13 road engine, over runs of at least two hours for each condition.¹
Power up 17.5% and 18.0% on average, with exhaust 20 to 32 °C cooler under load. In the laboratory's reading, more of the fuel becomes work.
Particulates down 68.6% on the Scania DC13, nitrogen oxides down 20.0% and carbon dioxide down 15.0% across both benches.

Same fuel. Higher cetane and octane.

Close view of the NTROPYX label and its 1 L : 50'000 L ratio

Cetane number 52 → 56. Measured on the road diesel with a CFR engine, ISO 5165. Across eleven analyses before and after treatment, the laboratory found no measurable change in the fuel's standard parameters. In petrol, it raises the octane number. Both bench tests ran on diesel, so octane was not measured there.

Three readings per sample. The CFR engine is first calibrated on reference fuels, then each sample is measured three times in a row and the result is the mean of the three.

One bottle. Every road fuel.

Diesel and petrol. The same bottle treats both fuels. It raises the cetane number in diesel and the octane number in petrol.
HVO and biodiesel. The road range covers both, alongside diesel and petrol.
Keep it away from electromagnetic fields. Store and handle the bottle away from transformers, high‑voltage lines and high‑power motors.

One litre.
Up to 50,000 litres.

Up to 50,000 litres

One 1 L bottle treats 2,000, 10,000, 20,000 or 50,000 litres, depending on its strength.
The bench dose. Both test engines were dosed at 1 : 20,000, one of the standard bottle ratios.
1 : 2,000,000

Made to order. Concentrations from 1 : 2,000 up to 1 : 2,000,000 litres, to each customer's needs.
Road freight. The 1 : 10 000 bottle, dosed at the point of fill.
Power generation. The 1 : 50 000 bottle for diesel generators.
One Dose. 40–60 litres from one 3 mL syringe, for passenger cars.
Made in Switzerland.

Printed on every label and on the One Dose sachet.

Diesel and petrol.
On the water, too.
