here you go. 98 RON (japan and europe) is about equal to 94 PON (US). most pumps in the states have 93. In california we get 91 and we still make just as much power as everyone else in the country.

Japan does NOT have significantly higher octane, and again I think the reason the motor that comes to the US is different has to do with the extremely tight emmissions control we have on cars.

 

now, leave me alone about octane hogwash, I'm apartment hunting.....

 

 

I think that you will find that the Hi Oku is in fact 100 RON ..... so there is a little difference I would say .....

 

right, 100 RON is eqaul to about 95 PON, which is NOT that different

 

like I stated before, there is a 4 point spread of what is available. You can run an S on 87 PON (about 91 RON) here in california, you just wind up with retarded timing. So again, I don't think that is the reason.

 

considering that is a 5 point drop in california...

going from 95 (100 RON) to 91(95 RON) most likely would NOT result in catastrophic failure of the motor. Just slightly retarded timing and maybe a bit richer fuel mix

 

Well it's closer to 96 PON .... but I get your point ......

 

thanks..... for what it's worth, that page I posted favours a wider spread of PON to RON numbers, I've seen 100 quoted as low as 94, so I'm not exactly sure what is truly acurate, but base on what I've, this page I linked is a best (or worst, depending) case scenario.......
