You do realize that there is a huge misconception amongst people that the higher the octane of the gas, the better/faster it is? Cars are designed to use a certain grade (octane) for optimum consumption and for most cars it is the regular unleaded (87), putting a higher octane pretty much means you are pissing away your $$, simple as that.
Motorcycles on the other hand, could actually benefit from higher octane as their engines make use of the higher octane and using lower octane gas could actually effect their performance but not so with cars built in the last decade or so...
