Best octane rating?
 

Hey all,

I haven't been able to find a recommended fuel octane rating in the PDF version of the service manual. Should I be using 87, 89, or 91?

(Note: 93 is not available where I live)

Thanks!

87 + appears to be fine
 

Found the answer on my own, but posting in case anyone else has this question in the future. I got my hands on an owner's manual (previously had the service manual only) and it appears that 87 is the minimum octane rating.
