Octane 91
Hi guys
I would like to know should I use 91 octane if I have a cold air intake and a full new exhaust with header and magnaflow catalytic converter and tanabe muffler? this is a 2007 Yaris manual with 228000km And it is true the octane 91 is more clean ?! |

You would require higher octane only if the compression ratio has been increased.
No 91 octane would not be any cleaner
