I pretty much always drive her on the hard side. But while the drive home is 20 miles of backroads, I usually never see the high side of 200 and to see 260 had me a little worried.
I think //M Ox is right, it's just taking longer to lose the heat out of this thicker oil than the 5W-30 which is causing the higher temperatures.
Still, I wonder why BMW would want this when heat is normally an enemy of engines??
