    20/1. Hunter Valley to Canberra running e10 94 octane, cruise control set on 115km/h, air conditioning set at 20c. Best: 8.0, average 8.2l. That includes being stuck on Pennant Hills Road for 40 odd minutes in the heat yesterday.

    BTW i dont normally run e10 but it was so cheap compared to premium 98 i thought i would give it a try.

    9000ks 12.9L pretty good I think but cost of fuel doesn't bother me

    That’s what I thought until I realised that $20-$50 twice a week could be better spent.

    Hi Monster, I have a stock standard VF2 Redline automatic for which I am considering getting an Oztrack tune. I want to optimise what is in the vehicle. I have however considered installing a flex-fuel sensor. The electrical side will be easy for me although I have not yet investigated what fuel connectors I will need and the exact under-hood placement of the sensor. Do you think it is worth the extra complication in a standard vehicle, that I am unlikely to modify? In particular I am interested in any extra performance from the ethanol. Fuel consumption is not a big issue as I usually only use the vehicle on the weekend.

    the flex sensors usually have the GM EFI clip on style fitting (same as the factory hard line at firewall) so u can fit them inline quite easily

    OzTrack will give LS3 a good tune for ethanol. Yes it is worth it on near stock LS3, mainly less effort / more power down low like 2500. So whether a little tip-in cruising or working your way up to 4400 OzTrack will recalibrate the tune to perform noticeably better than stock particularly under those conditions.
    Also on hot day giving it the boot it will stay responsive longer before heatsoak and timing retard.

    Thanks O7GTS and Monstar for the information. When time allows, it will be my next project.

    After 12 months, finally got to do a long distance trip in the LS3 Auto (A/C + cruise on + full boot + 98) at Easter from Gold Coast to Sydney. The 2 mainly Freeway legs were Port Macquarie to Sydney northern suburbs 10.1 l/100 over 373 km and returning from Port Macquarie to Gold Coast 10.0 l/100 over 475 km. The trip computer says best was 9.3 somewhere. Comparatively, my VE AFM did 9.1 - 9.3 in similar conditions. So not too bad really. Driving around Sydney - different story!

    I'm driving a Camry Altise hire car atm. I did Coffs To Macksville and return yesterday on cruise come, avg economy was 8.8l/100 on the speed limit. Lighter car, 4cyl, 1 person on board, no luggage. 4 cyl false economy, makes our V8's seem pretty darn good on highway.

    Yes quite amazing really, and not to forget the benefits of superior space, comfort, ride and handling for long haul trips, and the chance to get the jump on those rare overtaking lanes, it's the only way to fly (low).

    I’m driving a car half the weight and output of my wagon, more output yet 2/3 weight of latest VW Audi turbo 4 engine, is lauded as a triumph of engineering between BMW and PSA - recently won international Engine of the Year eight consecutive years - the posterboy of downsizing.
    Main thing is fuel economy is still same as it uses premium fuel and you know what’s the point spending more time than you need to out of boost?!
    Other thing is the fuel seems combusted petty poorly, like a light bit of oily sooty shiit gets caught in vortex behind white car need to wash every week!

    I averaged 9.9L/100 from Sydney to Gold coast and back 4 people and luggage.
    Same economy as my diesel Pajero. I can't complain about that :D

    I live in a very hilly area of the world, 700m above sea level. I guess around town, with my heavy foot, it's chewing through 16.9l/100km and on the highway somewhere in the 10's. I'll be interested to see how much worse it gets with the addition of a cam.

    The Camry I mentioned above was horrible to drive too btw. The steering ratio was appaulling slow. No road feel whatsoever. The cruise control was like a 1980's Mazda 929. It felt unstable at 100k's.
    It's all too easy to compare cars to our Commies on paper. But, driving many of them is a big let down in my experience.

    On a run to Newcastle from Melbourne I got 6.1 as we were about 50km from Sydney, soon disappeared as we hit Sydney's suburbs but I've still got it set as my lowest figure.

    Melbourne is 31m above sea level while Newcastle is 9m above sea leavel which means you were going down hill the whole way :p You still got great 'mileage' from your trip :)

    We should post fuel consumption figures with reference to the set distance setting (averaging over 25, 100 or 500 kms) as it makes it simpler to compare.

    Pity the speed average isn't linked to the 'set distance setting' used with fuel consumption average but it would also be useful to post this number.

    Me, IIRC, i'm getting an average from 18.4ltrs down to 11.4ltrs/100kms on the 25 kms scale with average speeds of around 34 kmph. It's very traffic and throttle dependant (and i don't hammer the go peddle).

    It's also a pity the instantaneous fuel consuumption display is capped at displaying a max of 34.9ltrs/100kms even though there is no hardware reason for such a cap.

    It would be nice to actually see what is happening when one takes off from the lights with other traffic but i guess GM/H are trying to be politically correct towards the greenies of the world by not showing the real uncapped figure. Gental take off from lights yields 24 odd litrs / 100 kms but is very very un fun...

    For comparison, my old EF falcon 6 cylinder POS pegger the meter at 99.9ltrs/100kms on normal take-off (the cap was due to the 3 character 7 or 9 segment display limitations of the trip computer).
