Apparently the US uses PON ( pump octane number ) as opposed to RON ( reseach octane number ) as in the UK and Europe generally. http://www.btinternet.com/~madmole/Reference/RONMONPON.html Your 89 PON is about 93 RON which is lower than anything available over here. The typical unleaded here is 95RON and called 'premium'. Aparently about 91 PON 'Super unleaded' is about 98 RON or 94 PON. Never seen anything else here. I found this in the owner's manual for my 9000 btw. " The APC system is designed to give maximum performance when 97 octane fuel ( RON ) is being used..... However.... the engine can be run on cheaper grades of low octane fuel ( minimum 91 RON ) quite safely. " Graham
