Update on consumption.
I was going to try to run the tank down on this run but couldn't drive past $1.08/l. So 497.8km from 60.16 litres, close enough to 12l/100km, 1 trip to & from the boat ramp (16km) with the trailer/boat, headed east up Greenmount , out to Merredin 110km/hr on GPS (115 on the dial) some dirt roads & one floodway crossing pretty much on cruise control the whole time on black top, aircon on the whole time.
