I AM only getting 16-17 litres/100km from my 2007 Holden VZ V8 Ute around town, and 11-12 litres/100km on the freeway. I couldn't get a clear explanation when I approached Holden, and the dealer's fix was to reset the computer, which they claimed wasn't reading the fuel consumption correctly. Despite this there has been no change. Any ideas?
I ASSUME you are getting your fuel consumption readings from your trip computer and not by a fill-to-fill check. If that's the case I would suggest you do a fill-to-fill check to make sure the computer readings are correct. The combined fuel consumption figure for the Gen III V8 is 13.0 litres/100km so I suspect your ute is not too far off the mark. I'm currently driving a V8 VE ute and I'm getting 17 litres/100km according to the trip computer.
