doing the reverse right now and i can't tell a difference from going from PC 94 to shell 91. have had about 2 tanks on 91. although my tank is a bit sloppy since i had some irving premium, no name mix and bunch of other mixed gases and some octane boost from my road trip. i should really burn that gas to 1/4 tank then fill'er.

The 94 octane (assuming AKI rather than RON) is worth it if you are tuned and running a little more ignition advance or the car sees hot laps on the track -- otherwise, I doubt you'll find much of a difference in power either.
On the other hand, it certainly won't hurt -- what's the price difference compared to 91 and can you get 93?

we also have select esso offering 93 (haven't tried) as well.
few cents more for the 94 compared to 91 at PC but imho i wouldn't get the 91 at PC if they offer 94
