Wrote a post below after 8K miles, now at 26K. The MPG for this car have steadily improved over time though there are seasonal variations (better in summer worse in winter). Anyway I have kept detailed mileage records and this car has done 45.9 MPG (calculated) for the life of the vehicle. I find the calculated is always ~2 mpg more than the dashboard reading. Breakdown is 48.4 MPG Summer & 42.5 MPG Winter. For the statisticians out there the overall sample size (tankfuls) is 61 and the overall mean is 45.9 MPG with a 95% confidence between 45.0 & 46.8. Std Dev is 3.56. MPG is still improving, and expecting to hit average 50 MPG per tank once Spring warm-up arrives.
