As a Canuck on US forums for years, have those conversion sites down pat LOL
Definitely, as speed increased above that 110km/hr, fuel mileage drops quickly.
I'm out east, no "winter" gas here, so no alcohol content. I don't pay a whole lot of attention to mileage on a day to day basis, but as the opportunity came up on this road trip, I decided to monitor it a bit closer again. With that said though, the car has definitely improved since new last October when I was seeing low 20's mpg in the same circumstances. Transport Canada's rating is 7.8l/100km, so still not that good yet, but again not bad for what it is IMO.
