Ernest.
My oil temp generally runs 10C degrees cooler than the coolant
temperature.
This is actually very desirable as the oil red line is 210F while the
coolant can go much higher.
Also it will take longer for the oil to heat up than the coolant as
it's thermostat is activated at 140F degrees allowing flow through the
cooler, while the coolant thermostat is usually at 180F, if
you have one installed.
Having said all that, I am currently using my oil cooler exhaust air
for cabin heat just because it was easier to do, since the oil cooler is
mounted to the firewall and has its own fresh air inlet and outlets.

Concerning cabin heaters, I had been
planning on following John Slade with the heater A/C combo until a
conversation with a fellow Cozy builder and he claimed that running the
hot water lines inside (as would need to be done on a Cozy) leads to a
possible failure mode that could cook the pilot and / or passengers.
Said hot water from engine escaping into cabin usually causes steam which
somehow is hotter that the water or is more likely to spray all over
the place and cause great pain to the occupants. Claimed
this is what caused one of the air racers to crash recently. Should I
change to oil for the heat ? If so, what exchanger will handle the oil
pressure and spikes of the rotary? All comments (sensible)
welcome.
