Anybody starting to think that the message read out is in US MPG, not Canadian....the max I got from my car was 24 MPG, straight out highway driving around 110km/hr...their rated at 31 highway. Anybody get close to 31, or is the gauge US only...it's got litres/km I know, but prefer mpg.

Anywhere from 9.8 to 10.2 liters per 100 km. Thats pretty close but the car isn't broken in yet I think it can still do better I only have about 8000 Km on her .
And yes you can flip the reading from km to miles it has that option for the computer.

Multiply the MPG by 1.2, to get the Canadian MGP.
If I keep to the speedlimit, and don't have a head wind, I have seen 30 on the highway.

The message centre uses US gallons
the most i've touched is 25MPG going about 125km/h, others have gotten better if they slowed down.
