hi octane unleaded

Don't confuse RON and MON octane ratings. The US runs MON/RON combination and their 87 octane is equivalent to our 91. So US spec bikes should run 91 or better.

I've never owned a bike that came with a manual

lifes too short to run 91 in a bike.
the only thing i ever ran on 91 (bike wise) was the RG.....and thats cos i got 8-10ks/L.
have tried to run various bikes on 91, always with dissappoiting results.
On the GB - it refused to run on anything lower then 96......mild cam would do wild things (in a bad sense) to my ass. The knock was horrible.
Sapphire turns into a bitch, and doesnt put out if i put 91 in her.

Not confusion, just quoting from the article - whats MON stand for

MON - Motor Octane Number
RON - Research Octane Number

MON - Motor Octane Number
RON - Research Octane Number

So NZ fuel is rated RON, correct or not

So you don’t need any "Carb and or Timing tuning" while pissing around with different octanes ?????

As i understand it (As an Ex-Bp employee) it was only the CORO (company owned retail orgaisation. or something) stations that were upgrading to the 98 Ultimate. Pretty much the stations owned by Bp oil Nz, and not the privatly run shops. Although i don't see why they couldn't supply the 98 Ultimate either.

We were told to promote the 98 as a 'better cleaner burning fuel, designed to make your car go further per litre and help it run more smoothly. An upgrade of 96 which it is perfectly fine to mix with'.
If custromers didn't like that I'd always point them towards Mobil across the road which provided better service anyway. (only 2 fill stations compared to our 8)

tried running my 02 tt600 on 98, seemed to go better with half 98 half 96. with a full tank of 98, it was hard to start. next tank i filled up with shell 96, going much better now, & starts straight away again. I've run the bike on 96 for 20,000k's so far, still on the same plugs...go figure.

Good question - the manual is set up for different parts of the world (Mexico being one) and I am pretty sure it was above 88 for Australia. I will check tonight and post my findings. Cheers :spudwave:

Another thing to remember for aussie is that they run like 15%-20% alcohol in thier gas which (i think) means that there is less carbon build up. Mot 100% sure of that but a few people have told me that now.

Okay thats the end of the lesson, a couple of things should be noted, you can’t get 91RON in europe anymore so 95RON is regular and 97/98 super. So if the largest petrol users on the road are cars, and car engines typically run at low compression ratios, meaning they work just fine on 91 RON, then why does 98RON exist at all, if for the most part it is a waste of money if used in the average car and average bike for that matter. Some how I can’t believe that the petrol companies are providing a product for the minority of people running high compression vehicles that need 98RON fuel. Looking at the advertising for BP ultimate, it makes out its great for your engine etc and clean, fails to mention that its no better then regular, smell a conspiracy.

So until 91RON is fazed out here, don’t be fooled 91 rules!

Because the Yuroppeans, bless their little petrol soaked socks, make quite a few cars, of which they are rather proud, which definately do require high octane.

The Alfatoy VERY explicitly says to use no less than 95 RON, with a recommendation of 100 RON. The Alfaisti would probably bring down the Eytalian government (well, at least reduce its term from three days to one) if the petrol companies were to decline to supply a petrol suitable for the Alfa, and Ferrari and Maserati and all the other beautiful , contrary beasts.

All this talk of 91, 95, 96 and 98 - when are they going to bring out some up to date fuels? How about an 05? Or maybe a vintage - I think 72 was pretty good.

I doubt if it's more than 5%.
