The previous tank was filled with 85 octane fuel containing up to 10% ethanol. Most of the tank was used above 5000 feet. As usual for the elevation, I didn't notice any issues with the non-spec rating even with the acceleration up the mountain. (The manual calls for 87 octane as a minimum.)

All of the activity yesterday was on this tank. The tank has a net loss of elevation, but it also includes yesterday's activity which was a net zero with a min-to-max variation of over 3000 feet. Today's run was mostly downwind which I'm sure helped offset the use of cruise control.

Finally, at 9500 miles on the odometer, the "oil service soon" announcement came on. This showed in the area on the left of the display that normally shows the temperature and the transmission selection that is used for all such announcements. These announcements replace the normal display. I don't like not being able to see the temperature gage. [more on this tomorrow]
