Gasoline octane?

[jtnyc]

Hey guys,

I just got a '08 ST3 and was wondering what type of gas to use. The owners manual says 87 octane minimum (and 89 for the 'tona)... what do you guys use?

Anyone experimented with different octanes and if so what were the results?

thanks

The book recommendation is absolutely fine. There is nothing magic about octane; it's a measure of resistance to pre-ignition, not a measure of "quality"; the real trick is buying fuel that is clean and uncontaminated. Already a thread on this subject, called (oddly enough) The Octane Thread. Please refer to it for more information.
