    Goes great! The car doesn't seem to start up quite as smoothly however.

    Used it once to track with it went well although not tuned for 100oct so bit of KR so won't use it unless I'm tuned for it. As a daily sure.

    No difference to car/performance unless tuned for it... Or you are getting heaps of knock... The ethanol gives you extra knock resistance

    No real advantages when I used it over 3 consecutive tanks. Extra cost, and no better fuel consumption.

    It's not too much more than United Boost 98 (one cent per litre), but I would agree about fuel consumption. Mine might have actually been worse when compared to BP Ultimate, but that could have been my right foot

    It will be worse since it contains ethanol

    Used for a little while. All I noticed was cost per km was slightly worse and the customer service was better there than at our BP
    Other than that, no difference.
    Nor should there be really

    Never personally used it...i avoid ethanol blended fuels

    Stick to 98RON would be my best bet..

    Not quite true...
    Due to the nature of modern engines, which have all these fancy sensors to pay attention to in closed loop... And alter the amount of fuel going in to meet required afrs...
    Due to the fact ethanol burns leaner than petroleum on an equal volume basis, more petrol will be required to achieve same AFR's...

    My car guzzled the 100, fuel economy went from 10.5/lit on bp98 to 12/lit per 100km on 100 octane
