Most stations in a given area use the same gasoline, just with a different additive package.
As for octane rating, in a stock engine use whatever the manufacturer specifies. If your engine's manufacturer only requires 87 octane, then it can safely run without detonation on 87 octane, and using a higher octane fuel is just a waste of money. Be grateful that you can actually run the inexpensive fuel. If your engine requires 91 octane, then use 91 to avoid detonation.
All stock or lightly modded D-series engines run fine on 87. DOHC VTEC engines require a minimum of 91.
If you have significantly advanced timing, internal engine modifications that involve high compression, and/or have power adders (including turbo, supercharger or nitrous) then you should use premium fuel as a precaution.
