What octane do you run in your 1MZ-FE

[ctak24]

I've been running 89 octane and I've been wondering should I go with premium or drop down to regular?

What do you guys run in your V6's?

This is my suggestion.

Yea I didn't really mean that this thread should be the one stickied but the question gets asked enough that it should at least be on the FAQ, and I know there have been some good discussions of what octane should be used with the 5sfe vs 1mz and why, I'll try to find one of them after I get out of work, Or maybe make a good explanation of octane rating and what it means.

incredible, I just realized that "worst" regular unleaded (95 RON) fuel in Europe is actually 91-21 octane (using US/CA index of AKI) ... what an irony ... and here in US it's called PREMIUM ...
then next step up grade (98 RON) is ... 93-94 octane (again using american AKI index) ... most states/stations around here don't even sell such fuel ...

AntiKnockIndex = ( RON + MON ) / 2

Charlotte's got 100 AKI all over due to the race tracks and what not. Might bump up to 91...

nice hehe, you ever tried it in your 1mz-fe yet?

I know some stations in NJ somewhere have the racing fuel too, and buddy (long time ago) mentioned they had something like 116-120 AKI fuel ... but it was of course terribly expensive ...

I know where I can pick up some 103 AKI [also known as (R+M)/2] in the middle of no where Bedford Country Virginia. ~$4.00/gallon, IIRC.

Nope haven't tried it. Can't too high an octane be bad as well?

For your wallet.... But yes, I think it can cause pre-detonation issues. But then again, i'm on zero sleep right now and need to stop posting on TN.

[Chris Crash]

That makes no sense. Wouldn't it just cause detonation issues period because it's harder to burn?

[LynchburgCSI]

Well... uhm. Cheese.

Nap time for Ken.
