Now at 1,500 miles
Overall average is 35mpg but nearly all my driving is on narrow rural roads - some single track and some unmade.
Only done one run on major roads - that was nearer 40mpg.

What I have noticed is a recent, and fairly sudden, increase in mpg - same route has gone from 33 up to 39 mpg.

Does the engine/transmission mapping change after a certain mileage?
