I have just done my first long run in the Scenic from Manchester to Devon and back.
On the way home i filled up at Sainsburys in Newton Abbott, reset the computer and jumped straight onto the A380.
The computer didn't register any mpg for a couple of miles then it showed 28mpg, by the time we hit Bristol it had climbed to 38mpg and when we got on the M6 it was showing 49mpg.
It went up 1mpg at a time, is that how it should work?
Also i have 205/55 tyres fitted and the originals were 205/50's. How much difference will they make?
