Trip to PA

[davidkerryedwards]

i was under the impression that synthetic oils would not necessarily run cooler
but
continue to perform their function at higher temperatures? What are the CAT
parameters
for oil temperature on your engine? You have piston oil coolers so I would
think that with
a steady pyrometer reading of 950, you would see pretty high oil temperatures.
I don't know how the CAT oil cooler system works, but my Mercedes has a
thermostat in
the oil cooling system that opens when the oil reaches a temperature which
requires
cooling.
Are these temperatures a new development?

mountains... I was
experiencing high oil temps in the 250* range, just a guess as the Gage reads
230* and
then 320* it was somewhere in the middle... with the water temps in the 190's...
pyro
temps running @ 950*... I am running 5-40 delvac synthetic... I would think that
the
temps would be lower with the synthetic... Is it possible the oil cooler could
not be
working properly??? I have been turning the fan override on when the water temp
gets to
190* which brings the oil temps down slowly... What are all your opinions as to
a fix???

this to
happen???
