85 octane
While traveling out west this summer I noticed most of the gas stations offering 85 octane and 87 octane as their mid grade. Has anyone tried this in their gasser? I wasn't going to try it especially ...

As stated, when at elevation, 85 octane is just fine.
BUT (read that a large BUT) this means only when driving at high elevation.
So, if you will be in mountain driving at lower elevation (say, when you are returning from high elevation to lower but still in some "upgrades to pull", do not fill with the lower octane.
We face this when we travel from home(elevation 22') to Angel Fire, NM (elevation 8,400'). No problem with 85 octane while in the Angel Fire area, but we wait until lower elevation to fill up when returning to Texas. The other option would be to fill with mid-grade when at high elevation stations.
