Unless you burn a LOT of fuel driving the exact same route day in & day out, you're facing the same data reliability issues everyone has who wants to test fuel and/or additives.
That said, by default, I think I'd probably go with regular in a car with a knock sensor.

Good points.
The vehicle is a commuter for my Wife (to work and school both), who has the same route except for the weekends. I would say she fills once a week -- FE is pretty stable at 29-31 this time of year (unless I drive it
). If it dips down to 27 or 28, then it may not be worth it (which is what happened during Winter). But Winter is Winter, as we know.
So, should the ECU be reset for such a change, or would that make it an unfair learning curve for a baseline?
We'll fill up with Reg next time 'round and see how it goes.
