    Owners manuals usually make a generic comment like minimum of 91.

    The octane rating refers to the ability to resist ignition under compression. Ethanol fuels have an Ron (relative octane number)

    The ecu with help of the knock sensors will determine the ignition timing. If you put 91 in your tank the ecu will be forced to advance the spark to prevent knocking, however this reduced efficiency. Whereas if you run a higher octane fuel the ecu can ignite it closer to tdc increasing the engines efficiency. (ignition timing is also adjusted for other factors such as emissions but that's not as much related to the fuel you use)

    While ethanol is very good ay resisting ignition under compression, ethanol has a much lower energy density than octane.

    I'm getting 13.0l/100km from my SV6, ave speed of 40kph I use Caltex 95.

    No idea if that's any good or not, but I do get less mpg from E10, when the Mrs has filled it up.

    Last tank in mine was 10.4 per 100 with an average speed of 75km/h. Cammed auto ssv on liquid injected LPG. $8.32 per 100km, cheap motoring :)

    I have a 2011 V8 with Walkinshaw exhaust and CAI. I generally get between 13 - 15l/100 around town averaging about 45. Its at the higher end if my wife drives it as she just can't help herself (and wonders why she gets the tickets???).

    Recently did a trip from Canberra to Sydney and got 8.2l/100 sitting on 113 kph on the freeway. Did a little driving around Sydney west and returned to Canberra on the same tank with an overall average of 9.1. Always use 98. Its a lot better than what my 2006 V6 Caprice used to get.

    07 V6,
    once in all highway 700km trip, I got lower than 9L/100km.
    on my regular drives it averages around 12L/100km (combined highway-city)... When I get hard on pedal for some fun it goes up to 13s, if I get smoother trafic it moves down toward 11.5L/100km

    Use "Fuel Doctor" from Super Cheap Auto.. in my VT commodore I get an extra 100kms per tank. I've just upgraded to a 2008 VE Omega and will be using it in it also. BTW - I've always used the expensive high octane fuel.. never anything other.

    The app is called "Road Trip".

    no use going from a 1.3 to a V6 and cry when you have to fuel it up..... naturally it will use more fuel, have a larger capacity tank, but i bet it's better to drive than the 1.3! When i had the Omega it ran better on E10 than it did on normal 91 ULP or 95 PULP. The SS has always been run on 98. The wife put E10 in it once, i thought something was wrong with it... it went from an average of about 12/100 to almost 14/100.
    At the moment it has a tune, CAI, under-drive, extractors and zorst and it gets about 11.3/100 doing highway and traffic. Last few days i have been driving it around town and not been overly kind to it and it's hovering around 16/100
    Fuel type and driving style makes a huge difference to your economy. Asking others can only ever be a very rough guide.

    All he did was reset the trip meter once he was driving at 100km/h on cruise control.

    LMFAO

    You owned a 4cyl 1.3 and bought an SV6 and your complaining about fuel consumption...

    err. Did you not read the vehicle specs before you signed the cheque at Holden?

    It is a big car compared to a little car, and a bigger engine compared to your previous pea shooter 1.3 4cyl

    If you want that fuel econ back, buy another corolla.
