I think there are too many variables to say for sure whether Chevron 91/94 will always come out top of Shell. As you mentioned, different cars and conditions will respond differently, and one would have to take the extra precaution to ensure which blend is being used from their gas station.

I'm not sure how the second run using Shell amounted in a 21HP jump from the first run on Shell. (Admittedly, I didn't watch the video.)
