Where I am 87+ octane is mid grade and above. I always wonder why given the extremely low compression on these motors, they require anything more than the lowest octane or "regular" (85 where I am). But there's really no point in second guessing anything Honda does or suggests. Perhaps because it's air cooled and they want to err on the side of being conservative given the wide temp range of operation?
