These days schools are closed. When I was doing school runs (20-25 km) it creeped up to around 9-10 per tank. In fact this is the last few avgs per tank so one can see. This is my workhorse car (96K km driven) so gets only usual maintenance from Honda 3S, like oil change and air filters on their recommendation. I have stopped getting the 'idle relearn' that they kept telling me to do every 5K km.

Jan-21 8.91 km / L, 10.08 km / L
Dec-20 10.08 km / L

Just went back in the app history and saw some avgs from Oct / Nov 2018, they were between 9-10 km / L.
