I`ve been driving much like you stated, keeping and eye on the tach and not hammering it off the line. With a 50/50 mix of highway/city, my mileage has been about 11.3 litres/100 K. That is on my second tank with roughly 800 kms on the clock. On the highway at 100klms (55mph) I`m reving about 1500, sometimes coasting I can rev about 1000.
Sorry for no MPGs on the gas usage...all metric unfortunately.
I love the vehicle and so far have no complaints.
Thanks
