    Not meaning to hijak this thread

    Do people find much diff between fuel brands? My personal perspective is that the BP Ultimate seems to provide better consumption than (in my case) V-Power. However thats my personal experience. I know full well that both are 98 and thus very little difference should be noticeable.

    I'm just curious as to ppls experiences. Has anyone had a noticeably different experience from one brand to the next? Or am I just smoking crack

    Currently, there will be a noticeable difference between vendors depending on supply points.

    Caltex + BP Refineries together provide over 90% of 98, 95 + 91 RON fuels to Australians, with Shell about 7%, Mobil about 3%. Caltex & BP have exclusive fuel sharing agreements, as does Shell and Mobil. Caltex & BP do not supply Shell, but BP supplies 98 RON (Mobil 6000) to Mobil from time to time when Shell cannot. Mobil only produces 91 + Diesel.

    Currently Caltex, BP and Mobil are the only companies in Australia with active Fuel Refineries. Shell's Refinery has been shut down since October last year with Cracker issues (the heart of the refinery), and therefore imports spec fuel from Singapore/India/Asia. Shell has not ordered any Crude (for March + April 09), so we suspect it wont be operational for another 3-4 months.

    So, basically to answer your question, Shell fuels are currently imported, and generally lesser quality (even though they have to be Knock tested to Aussie spec before releasing to servos).

    So, while Shell is 98 RON rated overseas supplied, BP + Caltex fuels are produced locally and we know where the crude comes from. The Crude most likely used to produce Shell's fuel is most likely dirty crude, and Shell will be blending sources from Singapore, India, and other supplies. Keep in mind that the RON rating is the main spec by which differentiates fuel. This is based on a certain Octane rating.

    Therefore, if the fuel is poor quality, Shell may just add Octane to meet spec, but the fuel may still be less efficient, compared to the nice clean locally made non-blended, Aussie made BP + Caltex 98 RON spec fuels.

    Above stats have been taken over 32 tanks of fuel, with a total of 14,362km since new. Car is driven how it should be and always use 98 octane V-Power or Ultimate.
    Yeah I keep detailed records too and this looks pretty similar to my figures. My vehicle is closer to 30,000klms now.

    it would be good to have a feature like most vehicles have already, shows how many KMs to go before an empty tank on the MPS

    The new SP25 has a trip computer. Which to me means that the new MPS will have it too.

    Oh and yeah! Good info Wardski... Why I try to use BP Ultimate when ever I can. Shell is too unpredictable. BPU is way more consistent which obviously helps with modified & tuned cars.

    I've done over 50 000klms in mine and have averaged 8.57l. The best has been 7.93. I drive approx 120klm highway, 60klm city per day. Usually get around the 500klms before i fill up.

    Sheesh....I can't believe the differences.....worst I've gotten is 400km - best 600kms! Driving like a nanna is the best - but I'm with Dotti - it's no fun!! My half nanna / half non-nanna driving I average about 450kms....I reckon it's worth it!! Definately have to use high octane!

    I drive mine as much as I can and the fuel consumption remains around the same. I fill up when the light comes on. Usually around the 400km mark and this usually takes about 48 litres to fill.

    I've just done 60,000 km's in mine. It used only slightly more when new.

    I use 98 RON from anywhere during the week and 100 RON on the weekends.

    Great info Wardski, I use Mobil 98 RON (8000), work account, no choice and with all town driving I get 370-390km and highway driving + city about 440-460km.I think there is better than Mobil but in my case it's better than paying for it.
