I guess so. How long is a break-in period, normally?

Also, cruise control, in my experience, isn't as good for fuel economy as driving with load and paying careful attention, so that might have some bearing on the situation.

The motorways between the city where I live and where I work are completely flat - and I mean flat. The cruise control holds the speed much better than I do - it rarely devitate from the set speed more than 0.5mph, where I deviate from the set speed a lot more so I spend my time accelerating/deaccelerating to keep to the set speed. I guess I could do a tank without CC to see if there's any difference, however holding the accelerator pedal in the same place for 800 miles a week isn't forgiving to my ankle!
