That's about right tbh. I can get 63mpg if im lucky.
Our dci 80 averages 65-70mpg on day to day driving (mainly single carridgeway A/B roads) but on a long run I can hit mid 80's no problem
What do you class as a long run? 100 miles plus?
I wish i could get 70MPG out of my car lol!!!
Its difficuilt to get them below 50mpg whatever speed lol
