Toronto highways are pretty flat for the most part (my "eco" light is on alot). Being in Canada everything is metric so I used an online converstion to get those numbers, maybe it is imperial ?!?! not that I know what that is LOL ... in metric my numbers are 10-11 L/100km hwy and mixed of 14-15 L/100km.
That being said, very rarely do I get a lead foot ... I take all my aggression out on the cars at work
