Reading on another discussion board, the Yanks all use 89 octane with no problems and suggest people don't waste the money on higher octane fuel.
So what the heck is ours made from... kero and cows urine???
You have to realize that different octane ratings are used in the US. Basically there are two ratings, MON (Motor Octane Number) and RON (Research Octane Number). US octane is an average of RON and MON, whereas NZ and most other countries use RON. US 89 octane corresponds approximately to 94 RON octane.
See the wikipedia entry for Octane Rating (http://en.wikipedia.org/wiki/Octane_rating) for further information.
