When you say trip computer, I can get two different readings from mine on the X5. If I reset it first thing in the moring or when I take off in the morning the mile per gallon goes high, once I reach hwy speed it drops down.

It can go from 12.6ltr/100klm to 8.6ltr/100klm on 15min run. I filled the tank up the other day, it took 86ltr of diesel, my computer said I would have a range of 1046klm from the tank and I know I am not going to get that around the city or combined driving.

For that diesel Porsche to get 30mpg thats around 8.2ltr/100klm give or take, no way unless he idle's around everywhere and turns off the Air-con. There is more chance of getting 30mp imperial gallon than a US gallon, and coming to that fact which gallon is the computer set to? mostly likely imperial as its a world wide car which means his trip computer is way out.
