Lower consumption in the driving cycle
The manufacturer states an average consumption reduction of up to 6% in the WLTC test. This driving cycle reflects changing speeds.

FUEL ECO TECH · PUBLISHED MANUFACTURER DATA
What the measured values mean.
The percentages describe a reduction in fuel consumption in the respective test comparison with and without FET. The three figures refer to different measurement situations.
A higher individual value in the test
The manufacturer states up to 8.8% as “peak consumption”. This is the stated peak value – not the average saving.
Peak value, not the value for every journey.
View key figures ↗Lower consumption at a steady speed
The manufacturer cites up to 15% for constant-speed driving. This applies to journeys at a steady speed, not to the mixed driving cycle.

Example calculation with assumed saving rates: cars 10%, trucks 15%, boats/yachts 20%. For construction machinery we use 10% as an example. The actual result depends on the application. Construction machinery and boats/yachts are calculated by operating hours; the payback period follows from your individual quoted price. Installation costs must be considered separately.

THE INTEGRATION
Simply integrated.
Directly into the fuel line.
The Fuel Eco Tech module is integrated into the existing fuel line between the fuel filter and the high-pressure pump. It works passively, requires no electricity and does not interfere with the engine management.
- 01 After the fuel filter
- 02 Through the Fuel Eco Tech module
- 03 On to the high-pressure pump

Frequently asked questions
What applications is Fuel Eco Tech intended for?
The manufacturer lists diesel and petrol vehicles, including cars, trucks, construction machinery, agriculture and shipping. Suitability and version are checked for your engine.
Where is the module installed?
According to the manufacturer, Fuel Eco Tech is integrated into the fuel line. Images illustrate the external principle; actual installation depends on the vehicle and manufacturer documentation.
Is a ten percent saving guaranteed?
No. The calculator uses an adjustable savings assumption. Published laboratory and practical examples are not a fixed promise for every vehicle.
