The I4 motors run cooler - my 2.0L I4 equipped DoKa will never drive you out
of the vehicle with heat - I am running an 87C thermostat and NO external
oil cooler and the oil temps are when I really drive it hard about 125C -
normal driving it is 105 to 110.
My Turbo Diesel is a different story - 120C normal driving and up to 135 to
140C with I drive the heck out of it on a hot day - I am now running an
external oil cooler which drops temps about 10C and there is really no
difference with the water temps nor the heat coming out of the heater.
Time for an auxiliary heater!

Subject: simple oil temp measurement.... will this work?
i want to measure my oil temp but don't have a fancy VDO temp sender, etc.
But i do have fancy temperature probes that are just a small wire i can
put anywhere (type K thermocouples). I would be happy to snake one into a
coolant line (like SeanB did once upon a time) but am a reluctant to do
that to an oil line as the consequences are much more sever if it
leaks....
so what about strapping my thermometer to the body of the oil filter? I
know the oil cooler is there, but my logic is that after a while, the
whole system is in equilibrium and the coolant won't cool the oil THAT
much, right? i mean after a while, like an hour or so of driving.
The motive of this research is two fold. I recently installed a cooler
thermostat and radiator fan-switch and would like some date to support out
hypothesis that is the the correct system for these rig's. And the second
point of note is this from driving this past weekend. The ambient
temperature was between high 20's to high 30's. When cruising along at
highway speeds, after about an hour the front heater would start to loose
it's burning hot air but instead more a mild heat would come out. I had
the rear core open and the rear fan on the 1st setting. I had the air
flow on FULL in the front. To get more heat i would throttle the front air
to 1/2 or 2/3 off. My concern is it may be running too cold. The
ever-so-accurate needle on the dash sits steady at 1/2 high at all times
once the engine is warm.
the books i have on engines always say the ideal oil temp is 109deg C.
Thanks
