I did a little evaluation after two seasons:

So far I've driven about 20,000 km with my Plus 4. About half of it last year and the other half this year.
I mostly drive on scenic country roads. I avoid motorways as much as possible (total share approx. 1%).

Average consumption total 7.34 l/100 km (38.4 MPG). Tendency falling.

2018:
Average 7.45 l/100 km (37.9 MPG)
Min. 6.34 l/100 km (44.5 MPG)
Max. 8,02 l/100 km (35,2 MPG)
The maximum was at the last tank filling before winter (so it's rather caused by low outside temperatures).

2019:
Average 7,18 l/100 km (39,3 MPG)
Min. 6.66 l/100 km (42.3 MPG)
Max. 7.58 l/100 km (37.2 MPG)

What is interesting for me is that the average consumption this year is significantly lower than last year. The driven roads were quite comparable. This year I have been partly even more sporty on the road (I have discovered that revs over 4000 RPM can be quite fun drive)

Here is a list of average fuel consumption per refuelling:

The first year ends approx. in the middle of the list after the average with 8.02 (l/100 km). The first value with (coincidentally also) 8.02 contains a longer (quite fast) motorway trip.

It can clearly be seen that consumption was higher at the beginning than later. So there seems to be a running-in behaviour.
