Wait...you do know that the 87, 89, and 91 aren't years right? They are octane levels. And you are also aware that you aren't supposed to put anything less than 91 in the G35 right?
I can't wait till they start selling the gas from 1994, that was a good year!

Also I hope everyone else knows that octane ratings do not = higher performance ratings. They are to designate one thing and one thing only, the fuels ability to resist preignition. The higher the octane rating, the higher the fuels resistance. So technically, a higher octane fuel is harder to burn in comparison.
