Here's a bit of a head scratcher, finally picked up the 17 Stelvio, started in Palm Springs at 110 degrees (yikes) went up the Sierra's (8700 feet at some point} 1400 mile ride. Oil was in the middle of the range the whole time until this am when it showed only a little bit on the dipstick, hmmm. Ran it a little and it was still low so I added some, by mid ride it was at the top....the only thing I could think of is the Oilcooler thermostat but that shouldn't change the level should it?
