Just did a 2100 kms (1300 miles) trip to Canadian Rockies from Vancouver with 2 adults and 2 kids and luggage.mine is 2009 with 3rd row and i got around 12.2 km/ltr (28.5 MPG) hand calculated by driving at 70~75 miles/hr and my Onboard computer is showing 12.1 km/ltr.So both readings are pretty close.New thermostat made a difference.
