High-performance engines typically have higher compression and are therefore more prone to detonation, so they require higher octane fuel. A lower-performance engine will not generally perform better with high-octane fuel, since the compression ratio is fixed by the engine design. Over time fuel looses it octane rating (resistance to detonation). It is generally not good to keep fuel for more than 3 to 6 months but it depends what you expect out of the fuel when you actually burn it. Whether you store it above or below is really insignificant. Some folks try to put octane booster in to over come this but this is tricky because folks don't really have the means to control over how much you change the rating, just my 2 cents.
