    I thought Shell didnt add ethanol in there fuels, because there are stations which say that there fuels have 10% ethanol, I thought the big guns didnt put it in.

    IMO I wouldnt waste money buying a premium fuel that has ethanol added to it.
    Ethanol is tax free for the petrol companies so optimax extreme should be cheaper than standard optimax which, as far as I know doesnt contain ethanol. I use E10 which is 95 RON and is 2 cents per ltr cheaper than standard unleaded and I am getting 9lt/100km on 60% highway 40% city. Im happy with that.

    don't bother with anything ethanol unless your fuel system (ie tank, lines, breathers) are absolutely 100%.
    Ethanol is hydroscopic and it will ruin tanks lines and engine if water gets in (promoting rust)

    E10 means Ethanol 10%, if optimax extreme has ethanol (dont like the idea of ethanol, these cars have not been tested in the long run for affects), then ill continue using Shell Unleaded 95 Octane, perfect for my car which is pretty stocks with minimal mods.

    I doubt very much that E10 would be approved if there was even the slightest hint that it may cause damage to a car. And there would be very strict criteria and testing to make sure of it. If octane levels in petrol (like shell's) are close to 100%, how can you have 10% ethanol?

    Ethanol is not good for polymer parts in the engine (such as plastics and rubbers), this may take sometime to affect.

    in short ethanol = bad...unless your car is specialy built to be tolarent to it. it is a very corisive material and in high quantites ruins cars.

    Exactly, the engine must be designed for ethanol, and 10-13 yrs ago they didnt really think about ethanol.
