You mentioned your oil temps being very low and outside temps being low.
Are you not concened about over cooling. Oil viscosity is dependant upon temperature. I would think that the oil being too cool you are not getting proper lubrication as it is too thick. The same for over temp on oil the oil becomes to thin and starts breaking down quicker. For me the optimum oil temps would be between 220 and 240 this is where the oil has its best shear factor for best lubrication properties.

Tell straight up if I am on the right path with this

Ideal oil temperature has been debated here many many times. I have never entered my 'opinion' ; however, having operated oil-cooled engines for the longest time, let me share my guideline that I use (see below)

"As suggested by Bruce Anderson, Porsche guru and author of Porsche 911 Performance Handbook, the optimal temperature range for the Porsche 911 oil-cooled engine is 180ºF to 220ºF. Also, according to Anderson, oil temperatures greater than 230ºF are potentially damaging. Yet, the old loop-style coolers started their thermostatically controlled cooling at 182ºF and later the electric fan coolers started at
244ºF! Again, some “experts” have stated that as material design improvements were made, like synthetic oils, engine parts, and gaskets, engine oil temperature became slightly less critical. However, most “experts” agree that cooler oil is better for engine longevity as long as the engine is operating at an efficient temperature of 200ºF."

I am not attempting to compare the Z to the Porsche; I am merely attempting to state what I have using as a guideline for my 'oil temperature range.'
