Hi,

I would like to know if it's okay to run less than 92 octanes in a USDM evo? I know in the manual say you have to use 92 octanes. Problem is I don't really have any idea on how much octane they have in Tahiti. People told me 94-96 like France and other told me 84-89...

I have an AFC in case the A/F get to lean... but not sure if it will be good to run less than the requirement.

I'm still trying to get some information about the gas in my country, but it's kind of hard to get accurate infos.

Thanks.

 

I put 87 and it ran okay. just make sure you are rich. factory tune does pretty much okay with any gas. I won't drive hard if I get less than 91.

 

87....damn...I only put 91.

 

i only put in 94

 

94???? oh yea..only on the East coast sunoco right>

 

damn, plz god tell! me Total or Mobil have at least 92+.
I don't want to use boost octane...
