Haven't done a whole lot of driving, so I'm only on my third fill-up. My first fill-up was after driving round Ottawa and that was 10.2L/100km, roughly based on 1) how much fuel it took and how many kms I drove and 2) the average consumption reading on the INFO centre and 3) the distance driven against fuel used on the INFO centre.
We drove to Gananoque avoiding the highway, so mostly 80km/h and driving round various small towns. We got 8.2L/100km based on the INFO centre (average consumption and litres used against distance driven).
Hope all that makes sense!
