I'd think it will probably run on 87, but a higher octane may be required to get all the performance the engine has to offer.

That's how it is with many cars and trucks these days. When they are running on 87, the engine's computer backs off the timing much of the time to protect the engine from detonation, but mileage and horsepower is reduced. You need a higher octane to get maximum performance from the engine. In fact, I believe the DOT requires new vehicles to be built this way.
