Eric,

Number one, you are totally off base in regards to not lubricating below
150. As long as there is flow, there is lubrication, at low temps. I also am
using Mobil Delvac synthetic oil, which does not break down until well in
excess of 450 degrees. We've had this discussion before about the factory
oil cooler (which the engine has), the problem is on long sustained climbs
through the mountains with a load, the oil temp rises off the gauge (160
C.), and drives the coolant temps up alson to the max, so it definitely
needs an additional cooler.
Thanks for your input though.

Karl
