Good info about fuel octane ratings USA vs UK

[pekespeed]

UK uses (RON) Road Octane Number which is a higher number we (USA) use Anti-Knock Index (AKI).
"In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock IndexAKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe.

some petrol stations in the uk have 102 octane mostly bp stations if you google bp102 there some good reading

true, the lowest we have here is 95 octane. Good enough for the RR

I read some here in the U.S. use regular 87 in their RR's and say the bike loves it. I may try it.

We get premium at 93 octane here in Florida (U.S.)...that's what I run.

There are several threads on this forum that explain why using anything more than 89 is a waste of money.

Sorry, I meant 89.

Here in Australia our regular is 92, premium is 95 and ultimate is 98(as BP calls it). The dealer told me to use premium at a minimum, most of our performance cars also say premium as a minimum. From 92 to 98 it's about 15 cents per litre difference, suppose to get better economy using the higher octane fuel. We also have 10% ethanol in some of the regular fuel and some stations carry 85% ethanol, I've never used it but you can get your car tuned to it and increase the performance using the 85% stuff, you tend to use more of the fuel with ethanol in it.
