Just did the sums. Broken Hill to Cobar with a side trip out to White Cliffs and back, 651 k's. This was the leg where we learnt the trick of blowing into the breather tube. My boy thought $1.73 a litre was too pricy in Wilcanna.
110 kph posted speed. We may have been a few kph above this. The screen fitted to the DR makes quite a difference with fuel economy if you are travelling at speed.
