I have now covered 1850 miles car returns 44MPG per half tank ( I fill up on half) I drive around 75/85 MPH depending on traffic, seems to be loosening up a bit now.
Strangely my Odometer says 43 MPG and when brimming it's two MPG more = 44/45 MPG, so it's pessimistic
not had that before.
I can get 50+ MPG if I stick to 67MPH.
