These should keep everyone busy for a couple of hours.

And if you really want to be confused, read the following (meat of it is
about 10 pages or so into it.)

re: "Your 91 octane in the US is PON? MON?" 

Our octane rating is always (RON+MON)/2; i.e. the average of RON and MON.
Our 91-octane has the same anti-detonation characteristics as Aussie
95-octane (guess Aussies like to use a bigger number--150mm sounds a lot
longer than 6inches ;). 

Never heard of PON, and a quick Google search turns up bupkis. 

bs (more appropriate than Bob at this point)
