    14.5 - 15.5L/100km doing about a 30/70% mix of highway/city respectively - avg speed about 38km/h, giving it a fair bit of poke, untuned.

    Hoping to drop a litre or two with a tune

    who cares about fuel economy when u have a v8 funny as it sounds if you whack a supercharger on them they are better again on fuel unless you put the foot down then you might as well own a servo...

    neppirt, depends on what sort of driving you do. If you do city driving, then look to a smaller engine with not as much power. If your doing towing or a lot of higher speed driving, then the bigger engines are better. That's general rule of thumb.

    But yea, if you want fuel economy for normal driving throw a supercharger on top! :P

    That's certainly not true these days. Mine with a tune is almost the same as my old vy v6 on a trip, and around 2 ltr/100klm around town difference, which isn't worth worrying about.
    I wouldn't go back to a V6 now.

    agreed above, full tune on the adventra is giving me between 12-13/100 combined driving (combination of nailing it and highway)

    On the open road eg. driving Sydney - Brisbane with 100-110kmh on cruise control I get 9-10 litres/100kmh fuel consumption. Around town it's about 15-16.

    On my VY II R8 285KW Clubby, 6 Spd Manual (factory) 3.7 Diff , I can get down to 6.8 - 7.0 L/100 km sitting on constant 100km/H or even at 110Km/H over long trips. I went from Sunbury to Phillip Island (150 Km or so) the other week and I averaged 8.2L/100 but that included some road works and 80-km/H spots with traffic.
    "Usually" the car sits at between 11.6 and 13.8 Avg L/100Km/H over a full tank of juice as a rule.
    When you give it to it though I have seen my avg L/100km around the 23 mark... which gets a bit pricy running 98 Octane.
    Cheers

    Got my VXII 255kw and on the highway got it down to 9.5ltrs/100ks untuned. my mrs 6 does about the same so yer getting a gen 3 is a BETTER idea than say a super six IMO.

    Yet the Super Six can get from Sydney to Melbourne via Canberra on one tank with left over. It was sitting on 6.9L/100km with a large 150km stretch being road works zone, heading down to some 40km/h stretches on the hume. That was bad... was about 12 months ago.
