Can you guys get 98 octane, like here in oz.
Im just wondering why all the performance chip recommend the use of 91.

Yes and no.

Most states in the US top out at 93 or 94 for standard pump gas, there are some stations that have a seperate "cam2" race gas pump that sells 98 or 100 octane unleaded, and usually a 110leaded. I've never seen anything higher than 91 in California.

Rednecks here go to the airport to get 110 for their high comp dirt track/drag cars. It's mad $$$.

I think all California is 91 max unless you go to the racetracks they have the higher octanes.

there are a very few select gas stations that will carry 100 or 110 in socal and a few in norcal otherwise most are 91

We use a different rating system. We use PON and Aus uses RON. 98 RON = 94 PON.

Beat me to it.

Sears point raceway has the higher octanes, i think they have 110

92 here in Oregon, but there is a place in town that sells non-ethanol 110 for ~$8 a gallon. Lots of places have non-ethanol 92 for $2-$3 more a gallon.

No reason to have 98 everywhere in the US, we don't drive like this:

They had like 116 when I was there last year. Which is ~120 RON.

[Thizzelle]

yeah i thought i saw 120 before, was thinking about filling up my M3, roommate works there so he could have done it for free, but chip is tuned for 91.

E85 is 105 octane (RON+MON)/2

If you're not getting detonation or the ability to advance your timing more and tune it for more power with that timing, there is no advantage to a higher octane fuel.
