    Thoughts on E10 vs 98 vs 91

    So i have only used 98 in my VE SS and but is there a noticeable difference in using 91 or E10 or is it bad for the engine? or is it a myth that E10 slowly destroys a higher performance car.

    One of the shops in Melbourne did a comparison set of dynos. E10 was embaressingly good for power almost trumping 98. From memory Rob Vickery HPF.

    Isn't E10 more expensive than 98?

    I've said it before and I'll say it again.....

    In terms of "Bang for Buck"

    91<---95--E10-----E10(with tune to suit)->98

    I'm currently evaluating my fuel choices. I think I'll be going to an Ethanol blend as I've taken 98 about as far as I can on the tune. It's a pity Shell got rid of E10 as I'd be running it in the SIDI if it was available.

    Thoughts on E10 vs 98 vs 91

    Aparently tt did a test a while bac on the cons of fuel pricing and although e10 was the cheaper of the fuels compared to 95 and 98 it consistently tested at 96 Ron so maybe worth considering

    E10 may be cheaper but I have always thought consumption was higher than using 95 or 98 due to the lower octane rating

    e10 is higher octane than 95, closer or even above 98. consumption is very slightly more, because the ethanol contains oxygen so needs more fuel to compensate. but this will not be enough to oughtweigh the $$$ saved over using 98

    Do I need a retune or will the car adjust over time for the change of fuel,usually run 95 with the rare tank of 98

    eflex is the bomb! it's a shame it's not more popular. 2 years of nothing but eflex running in my car and loves the stuff. Drives much better than 98.

    You dont NEED to retune, but i suppose a tune would give the maximum benifit

    Pretty keen on eflex myself, the only problem being there are only 3 service stations in Newcastle area who sell it and outside Newcastle im not sure its available except sydney.
    Can anybody tell me other locations i can get it? expecially close to eastern ck, whats the closest servo? cheers
