It has to be the engine thermostat letting oil flow to your cooler prematurely. I was also having trouble with low oil temps on my stock 3.2 I pulled the engine oil thermostat, did the hot water check and it operated as it should. Re-installed the thermostat and same low temp. Replaced the thermostat with new and problem solved. Doesn't make sense to my practical mind either but I rationalized that it could only be the engine thermostat and it was.
