yep says the same thing in my manual, it also says 91 octane
i ran shell v power on 8 degrees and it ran like a old 3 legged pig, so after a couple of days i tried bumping the timing up to 15 degrees and taking it around the block. i did that a felt a difference so i left it there.
but i was running 91 on 8 degrees for a couple of days, it was pinging/ detonating you name it
