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?

Not sure on the scenic but on my Lag II the MPG on the computer used to go up in 0.4 increments I think.

The tyres wont make a difference at all mate. They are just a higher profile, and will give you a slightly better / comfier ride that all.
