The main purpose of running a higher octane is to avoid detonation (pinging) which can cause real damage to pistons and cylinders. Higher octane fuels will be more necessary at lower altitudes. If your running a 93 octane (if you can get it) in Denver, you're wasting your money. On the other hand if you're running a lower octane at lower elevations, you're asking for trouble.
If you tour to different altitudes, consider upping your octane as you come down in altitude.
I live at 2000+ ft. I use an 89 or 91. 93 is not available, or necessary, here.
