MPG Testing AR-5 + 93 Octane

I'm most excited about the full size spare on board, as I'll be mounting mine on the rear in the near future, and I was worried about how it might affect gas mileage.

Probably not at all. I didn't notice any difference whenever I stopped carrying mine. The roof however is an entirely different matter.

I can imagine. Roof mount = wind resistance FTL.
