I live in alberta and am wondering what kind of fuel you run with it. I guess its supposed to be run with 96 octane but that is not available here of course. Just wondering what octane you run it on and if you add anything to the fuel.

As I've been told numerous times, and have finally shown for my self, our JDM cars will run on 94 octane just fine even at 12 psi.

You can likely get away with the 93 octane that is local to you on anything less than 12 psi.

Of coarse that isn't to say it wont like 96 ;)

I run 91 octane from Petro can and its fine. I've used 94 octane from husky and its fine too. I haven't noticed a difference but my boost is stock right now.

Yes remember that Jap fuel is not on the same scale as ours (RON/PON).

It would be preferable to run 94 if you can. Failing that, use as high as possible. Just keep an eye out for knock response. If you feel *any* at all....stuttering, hesitation, etc., take it extremely easy until you can get better gas or resolve the situation. An alternative would be to install something like water injection to help out.

I run 91 all the time. That is the highest here and I don't have any issues running 12psi all the time regulated with a ball and spring MBC (at least that is what my gauge reads). In the winter no problems and in the summer I put in some octane boost with every tank when its really hot out or for an AutoX.
Its not an oil leak... Its sweat from all the horse power!

In Montreal, the only 94 we can get is from Petro-Canada and is blended with Ethanol...so I stay away from it!

I go with 91 from Shell or Ultramar ...And I take it easy in big heat days!

The stock 3S-GTE only needs octane number 91 as specified in the manual, however running higher octane is recommended.

I use the highest grade I can get (usually 94) and my car idles really smoothly.

I've always wondered if the 94 pump gas, say in Alberta, is of the same quality is the 94 pump gas in Ontario.
Maybe the 91 is high quality in one place, & 94 is of lower quality somewhere else, so they really both perform close to the same?

I guess I have no idea, and don't really trust how well fuel octane levels are monitored before it's shipped to the station.

Maybe 91 octane gas is as good here as the high quality stuff in Japan?
