I have finally plugged mine in. Played with it a bit this morning, and got some interesting results!
Figures so far, lifted from the other thread:
Scottish Ian 8.8
Pezza 7.1
H.7 5.74
Wirdy 5.4
I have done a 6.02, 5.79 and 5.74!!! Interesting eh? Maybe my car has mods that I am not aware of? Or maybe I set the meter up badly? I'll play some more later. That was with me, a small number of tools and about 15 litres of optimax on board. The ambient temp was about 3 degrees, so nice cool air going in!
I weighed the car yesterday evening and came up with 1660 kg. That was with 1/4 showing on the petrol gauge (I think theres about 20-25 litres left at that point?) and no-one in the car. For reference mine is a pre-facelift auto legnum with leather.
