I'm a little late chiming in, but here's my experience, good or bad.  My 2.0
engine with approx. 30K on it runs anywhere from 160F to 240F under fairly
predictable and *normal* circumstances:  hotter on hot days and at high
freeway speeds, cooler on cold days and at lower speeds.  The oil temp
climbs significantly when I am climbing steep hills, whether fast or slow.
It will occasionally flirt with 250-260F under extreme climbing (like the
11,313' Monarch Pass in Colorado).  I have been told by a well-respected
Vana-guru (and bus guru) that this is pretty normal for an air-cooled
engine. "Don't worry, be happy"!

I am happiest when it's between 180-220F.

My experience only, neither right nor wrong.
