We fitted a Mercedes E280 with a CarTuner from Swiss Harmony because we wanted to find out whether the installation actually reduces fuel consumption. The CarTuner was attached to the positive terminal of the car battery. It causes interference suppression of the electrosmog. As a result, the driver and all passengers are significantly less stressed and less exhausted even after long journeys. In addition, fuel consumption should also be reduced. Depending on the driving style and the type of kilometers driven (highway or city traffic), the savings should be between 5% and 15% of normal fuel consumption.
Every car is different and every person drives their car differently, so the results can fluctuate greatly
