Reading about Omnis consumption create feeling of uncompetence and envy. My is around 7 l/100 km. Ok, I am lazy to make such statistics, as usually visiting petrol station morning on way to work and I use just ECU dash board information. I will try to change it and to make notices and see.
I think, problem is on me. I used to drive in urban area and my low riding experience is shown in probably not effective riding style.
But anyhow, you have very nice consumption.
