RON Ratings - sorry Just_J - but all of Europe also uses RON (as opposed to (RON+MON/2).
BTW US fuel = 86 or 90 RON depending on where you are - though I have heard of some states selling 91 and even 92. In Europe stock fuel is 94 and higher octane is either 97 or 98 (though in Germany I beleive BP sell 100 octane).
In Japan they well 90 and 100 Octane fuels.

jap fuel is close to ours... its not 100 and 91 here.. its closer like 94 jap 93 america... that isnt exact... but close, they do have higher oct... but not by a huge amount.. you are just getting caught in the different methods used to measure it.

exhaust coming out of your valve cover mostly like says theres something wrong with one or more of your intake valves maybe bent or not seating right and allowing a leak,i think. If anyone thinks im wrong or knows somethings else that could cause it,post it, i would love to correct errors in my knowledge

Sorry what? I'm in the US, we use (RON+MON)/2, it's on every gas pump. 91 Octane is the minimum for "premium", where I am they have 92, and 93 in some spots.
The fuel here is ~86 for regular, ~88 for plus, ~91 for premium. Up the street, to be exact, it's 87, 89, and 92. There's a drag strip with 100 octane unleaded. :-D
JC, the car you're talking about is the Spec C. They're probably throwing on a different name for the AUS market. I hope they bring a Spec C version of the USDM STi over. :)
I'd say the Version 6 STi Type RA is one of the best ever made. Such a sweet car. :) The new Spec C is wicked fast however. The rumor mill is churning about the next USDM STi, I know the WRX here is getting a bump in displacement to 2.5L, and a jump in power to 240 IIRC. I'm curious to see if Subaru increases the power of the STi to compensate for the uprated EVO.

Actually, you are off base on the intake valve thing.
If detonation breaks the rings, or the piston ring lands(grooves), the combustion gasses will enter the crankcase. This is the source of exhaust I was referring to.(in the context of the fuel quality discussion)
