87 grade so far, car runs good and best I get is 6l/100km at 80km/h OR 40mpg at 50mph (in Canada we have 80km/h national roads)

How did you get this kind of mileage? is it pure highway and just leave it in cruise control? So far i only got it down to 8.3L/100km but this is for only a few mins on the hwy.
 
Yes, pure Hwy, cruise control, Smart mode, pretty flat road with a few hills, one person in the car and about 10deg C outside.

I see. I did a 2 hour hwy trip before but this was in winter. -11 Celsius outside. I was steady 125km/h on cruise control and i got horrible gas mileage lol. I believe 12L/100km. But i know for a fact because it was cold outside.
