I don't notice any knocking with 87. Sounds identical to when I run 91. FWIW, Porsche says the same thing and recommends like 92 or 93 or something. We can't even get that out here very easily. I'll run the required octane. If that ends up being an issue, I don't care. The only time octane concerns me is if I'm beating on it, summer, altitude (i.e., more strain through passes).
