Consumption with Fuel Saver: 9,10 l/100Km
Savings: 19%
Yes it really made a difference.
I compared the average consumption of 2 years ago to that of last year. In 2011 it was 11.2 l/100km, in 2012 it was 9.1 l/100km with the ECOPower-Fuel Save and this with an Audi TT (2 l 200PS) in the city of Berlin.
