New Record: 41,9 MPG (5,62 ltr/100km) on LPG. This is equivalent to 4,5 liters of petrol (LPG has got 20-25% less energy) which means 52,3 MPG on petrol.
243 miles on Autobahn, 200 - 800m elevation, no hypermiling techniques because of difficult weather conditions. Used drag of lorrys for approx. 180 miles.
It was raining all the time and i had crosswinds. Lights were on. Heating fan level 1
I'm pretty satisfied with that.
