    Lists all the sites ( mostly SE ) of Tesco 99 Ron SUL outlets.

    Sticky maybe ?

    I expected the opposite

    Taken from PH
    It's 5% alcohol (ethanol). Ethanol contains oxygen so can be seen as already partially-burnt fuel... burning ethanol produces less energy than burning the same molar quantity of ethane (the relevant hydrocarbon).

    However ethanol has a higher knock resistance (octane number) and thus can be raised to higher compression ratios in engines without detonation. Higher compression ratios allow higher power outputs.

    For turbo engines, the increased knock resistance will allow the ECU to maintain higher boost levels without detonation, thus producing greater power outputs in less than ideal conditions (i.e. high ambient air temps, etc.).

    heard from people on the scooby club and the celica club their EBC's going mental as the knock value was really high.

    my car also spluttered like mad from it, back on optimax methinks

    It's still nowhere even remotely local to give it a try. Although reading about it, I don't think I want to anyway.

    My Pulsar didnt like the Tesco 99 ron, it would splutter and idle quite lumpy. But my Saab 9-5 has an adaptive ECU and loves the stuff.

    Was no better than standard 95 or 97 in my 1850. Prefered Optimax.

    My Volvo T4 has an adaptive ECU but hates Tesco 99ron fuel. All was cured by going back to optimax though.
