Swiss Fuel Services


In a recent, independent test carried out by Swiss Fuel Services (based in Zürich), our innovative SulNOxEco™ Fuel Conditioner has delivered a 12.6% average fuel saving over 20,000km travelled across its 3 test vehicles. The results of the test are detailed below.

Protocol – Test vehicle in field test with SulNOxEco™ fuel additive

Vehicle manufacturer/type:BMW 320d Touring, year: 2021, capacity: 1,995 cc
Tank capacity:60 litres (optional equipment, regular 40 litres)
Fuel consumption:6.5 litres / 100 km according to factory specification
Notes on the field test over 4,000 km driven with the test vehicle.

The test vehicle was inspected by TÜV SÜD as part of the emissions measurement and calibrated on the TÜV SÜD test bench at the beginning of the field test.

On a defined reference route (see below), the consumption of diesel was determined before the start of the field test with SulNOxEco™. The diesel fuel was then treated with the fuel additive over a total distance of more than 4,000 km. A total of 5 tank fillings were applied, each with a dosage of 30 ml SulNOxEco™ per 60 litres of diesel in the refuelling process.

Results from the route and driving profile of the reference route

Without SulNOxEco™ application: Schaffhausen – Heimsheim, 12.02.2022 Departure 10:30h
The reference route (A4 – CH, A 81 and A 8 – DE) was driven with the test vehicle according to speed limits. On sections without speed limits, the speed was 120-140 km/h, max. 160 km/h.
This results in a consumption value of 6.0 l/100 km.

With SulNOxEco™ application: Schaffhausen – Heimsheim, 21.02.2022 Departure 07:00h
The reference route (A4 – CH, A 81 and A 8 – DE) was driven with the test vehicle according to speed limits. On sections without speed limits, the speed was 120-140 km/h, max. 160 km/h.
This results in a consumption value of 5.2 l/100 km.

The field test with SulNOxEco™ shows a test result of around 13% fuel savings per 100 km.


Protocol – Test vehicle in field test with SulNOxEco™ fuel additive

Vehicle manufacturer/type:Mercedes-Benz S560 4matic, year: 2019, displacement: 3,982 cc
Tank capacity:80 litres (optional equipment)
Fuel consumption:8.5 litres / 100 km according to factory specification
Notes on the field test over a distance of approx. 10,000 km driven with the test vehicle

The test vehicle was driven primarily on long-distance routes as part of business trips (SEMREV AG board vehicle) in the period from Nov. 2021 to May 2022.

On a defined reference route (see below), the gasoline consumption was determined before the start of the field test with SulNOxEco™. The gasoline was then treated with SulNOxEco™ over a total distance of more than 10,000 km. A total of 10 tank fillings were applied, each with a dosage of 80 ml SulNOxEco™ per 80 litres of gasoline in the refuelling process.

Results from the route and driving profile of the reference route

Without SulNOxEco™ application: Schaffhausen – Hamburg, 12.11.2021 departure 10:00h
The reference route (A4 – CH, A 81 and A 8 – A7 DE) was driven with the test vehicle according to speed limits. On sections without speed limits, the speed was 120-140 km/h, max. 160 km/h.
This results in a consumption value of 9.4 l/100 km.

With SulNOxEco™ Application: Schaffhausen – Hamburg 23.02.2022 Departure 11:00h
The reference route (A4 – CH, A 81 and A 8 – DE) was driven with the test vehicle in accordance with speed limits.On sections without speed limits, the speed was 120-140 km/h, max. 160 km/h. This results in a consumption value of 8.1 l/100 km.
This results in a consumption value of 8.1 l/100 km.

The field test with SulNOxEco™ shows test results of 13.8% savings per 100 km.


Protocol – Test vehicle in field test with SulNOxEco™ fuel additive

Vehicle manufacturer/type:Range Rover Evoque TD4, year: 2017, capacity: 1,999 cc
Tank capacity:60 litres (special equipment, regular 54 litres)
Fuel consumption:7.6 litres / 100 km according to factory specification
Notes on the field test over 6,500 km driven with the test vehicle

The test vehicle was inspected by TÜV SÜD as part of the emissions measurement and calibrated at the beginning of the field test on the TÜV SÜD test stand.

On a defined reference route (see below), the consumption of diesel was determined before the start of the field test with SulNOxEco™. The diesel fuel was then treated with the fuel additive over a total distance of more than 6,500 km. A total of 8 tank fillings were applied with the dosage of 30 ml SulNOxEco™ per 60 litres of diesel in the refuelling process.

Results from the route and driving profile of the reference route

Without SulNOxEco™ application: Schaffhausen – Heimsheim, 25.03.2022 Departure 08:30h
The reference route (A4 – CH, A 81 and A 8 – DE) was driven with the test vehicle according to speed limits. On sections without speed limits, the speed was 120-140 km/h, max. 160 km/h.
This results in a consumption value of 8.9 l/100 km.

With SulNOxEco™ application: Schaffhausen – Heimsheim, 28.04.2022 departure 07:00h
The reference route (A4 – CH, A 81 and A 8 – DE) was driven with the test vehicle according to speed limits. On sections without speed limits, the speed was 120-140 km/h, max. 160 km/h.
This results in a consumption value of 7.9 l/100 km.

The field test with SulNOxEco™ shows a test result of 11% fuel savings per 100 km.
