Hi Kate,
Who would know best? Considering you bought itfrom me

, and the engine had been seen to by DLK so it behaved perfectly I can tell you what I achieved on my last long run out. Driven steadily with a fairly light foot and using the cruise control on the mway I turned in a healthy average of 37mpg for a journey of 398 miles of which only 60% was mway. the rest was 25% A class and the remainder B class roads.
Don't forget that you will alwats get better mpg if the AitCon is not on. Turn it off by having the ECO button
lit up.As with every trip it depends on how it is driven so wear light footwear and leave the diving boots at home

.
Last but not least, pulling an
independently unbraked trailer will entail you not exceeding 50MPH and will also reduce you overall mpg.
Keep the display showing the Instantaeneous consumtion and it will encourage you to lift the foot off! It worked for me when I was tempted to put the hammer down. The sudden massive drop to single low figures

soon made me lift it back off the go faster pedal.
Hope it goes as well for you as it had for me.
I miss it

, even though its replacement is far beyond what I expected!
