Octane Ratings from around the world

[Gonthrax]

Actualy I was wrong about the RON of the "racing fuel" at the local service station, its 110 RON.

I'm pretty sure they use the MON (motor octane number) in the US. Can't remember where I read it though. That would also explain the differences in the octane ratings.

in reply to brendonm on 12/03/01. the octane numbers in the usa differ. but they also tell how rich the fuel is. 87 is the lowest i have seen which means it isnt as rich as the others. they dilute the gas to make it not as rich. the higher the number the richer the fuel. so if your using anything over 100. that is some rich as fuel youve got there. there are also different types of fuel. indy cars use ethynal which is maybe 102 or higher which burns clear and is highly rich for there type of engines.:bandit:

in the UAE ( United Arab Emirates ) The highest octane rating you can buy from a gas station is from Emirates Petroluim 99 Ultima ,,

Followed by Eppco fuel station at 98 RON ,,,

Pretty nice those are the only 2 unleaded fuels we have the rest are leaded at 97 and 96 I belive....

From what I was told by the way they are calculated, 98 here in England is like 91 back in the good ol' U.S. of A. So, they have crap fuel here a long with crappy roads. I still like this place, damn I am dumb
