Hi,
I have crossed 700km and I thought I should share an update.
My average has increased from 6.25km/l to 8.0km/l. On empty roads and longer drive (18-20km long), I get 8.5km/l max. Two services done on time (1 and 3 months).
I am enjoying the ride and only need to fill my tank once a month. Really comfortable ride and I don't get tired if stuck in traffic for 2 hours.
