Thread: Stndard or super fuel pros and cons

    Re: Stndard or super fuel pros and cons

    G'day
    Far from an expert but what I've read says higher octane is less volatile (less power in my mind)
    I saw test of additives that raise the octane level in a racing team lab, power went down with increased octane
    If you leave fuel sitting around, particularly in a ventilated container the light more volatile components evaporate and the fuel starts to degrade and the octane level goes higher
    Higher octane is for high compression engines that may suffer pre ignition from using more volatile (explosive fuel)
    I use a simple approach, just use what is recommended by the engine company
    Cheers
