Say you're on a turbo setup, you're on an average amount of boost. You're supposed to use 93 octane or whatever highest to avoid knock. Let's say for whatever reason, you had to run 87 octane, is it safe to use the lower rated octane fuel if you stayed in vacuum and stayed out of boost or is it still not a good idea.
Question about turbo/boost and 87 octane?
