You're changing your mind.
We have gone from 40MPG on a motorway to 35 MPG on a motorway
The @ 56mph consumption figures are exactly that. I.e. a constant uninterrupted 56mph , no stopping , no accelerating to move round a lorry, no slowing down for congestion and the accelerating back up to the 56mph. In other words it's nonsense and virtually unachievable.
Now, given that the 56mph figure for a 2.0 is in the low 30's MPG, and was conducted on a brand new shiny Fronty , what makes you think your 20 year jalopy with a new air filter and oil filter is capable of exceeding these figures ?
