We get 42 from our 1.2 but that's the type of driving(very urban)

If car read 46mpg, expect a true 44mpg and you've given proper run in ideal conditions. That suspect as good as you'll get. You could do a 12 mile A road run and after include stopping at lights it might do lot better. That test as close to new economy tests as can do yourself. They like average speed of 42-43 mph basically. My first Fiat ('03 Punto Multijet) got reading 88mpg on A road run. In reality it normally did 46. Both figures off trip computer so not accurate.
