That’s a good point actually. For the last 8-9 fuel stops, I’ve reset my trip. My average is 400miles on 60ltrs so really, my overall average ends up being closer to 30mpg...if I’ve worked that out correct?!?!?Is that what the MFD is telling you or are you measuring via brimming the tank each time? If its the MFD, chances are, based on the experience of others, its reporting somewhat more than you are actually getting. Either way, it looks like you are getting very good MPG. Last time we went to Bala (circa 130 miles each way, 150 DSG, fully loaded with a boat trailer and bikes on the back) my MFD reported 51 mpg but in reality I seem to be getting anything between about 38 and 45 (hard to get accurate figures as most tanks have an element of Eberspacher heating to take off) - still more then happy with that!!
Edit: I pretty much tow all day every day too
