Figured I could occasionally mix the two to get roughly 93 octane if it was worth it. I know the STI's are meant to run on 93 so west coast STI's see slightly decreased performance due to 91 octane fuel. Just wondering if the Z is similar in that it would benefit from 93 or not. By the way this is in regards to stock trim. Thanks
Does your engine ping on 91? No? Then don't bother.
