Thanks Orion for digging out that study. That's an interesting outcome ADAC had. Hard to to argue with a club of that size about the outcomes of that particular study.
The remaining question is of course why the hell that product worked on my car, on JJ's car, in a driving school (where students knew nothing about it) and at a company delivery van where the driver thinks it's just to clean the injection system because of bad fuel in that particular region.
Is it a placebo effect? Well hard to say, I'm driving very sportive and always at higher revs. Therefore my fuel consumption is always higher than with a "normal" driving style. Adding that FFi stuff did not make me drive more "careful" with the gas pedal. Same with my wife, she drives how she drives.
Anyway my personal conclusion is:
If that's a placebo effect that drives down my consumption by 10% and costs USD 2, I'm willing to pay that 2 bucks.

'Tis pleasant purchasing our fellow-creatures;
And all are to be sold, if you consider
Their passions, and are dext'rous; some by features
Are brought up, others by a warlike leader;
Some by a place--as tend their years or natures;
The most by ready cash--but all have prices,
From crowns to kicks, according to their vices.
