I would use a minimum of 91 octane in the car. If available, 93 octane would be the best choice.

91 octane "mogas" from the local airport (no ethanol) at $5/gal or 93 octane Mobil @ $6?

To be clear, mogas is not leaded avgas.

Is Mogas Top Tier? In general, I'd say go with Top Tier, but at a buck a gallon difference, and probably slightly better mpg, I'd be very tempted to go with the 91. Maybe run a tank of Top Tier every third tank.
