Would anyone recommend an Oil Cooler Bypass Valve

My water temp rarely exceeds 195 either, but the fan hits on at that temp so all is good.
basically the car runs cool vs hot and never have any issues.

It is generally accepted that oil needs to get to 180*F to operate correctly. Oil tests for viscosity, wear, etc, is usually done at 100*C. 80*C is about 176*F. Your temps are close to operating temps but not quite there yet.

I'm not sure what you mean about the thermostat, though. You want it to stay closed until it hits 195-200*F or so. 195*C is over 300*F. I suspect you mean 195*F is when the thermostat opens.

But, even when closed, it allows about 10% of the oil to flow through the cooler. That's why your oil never gets up to operating temp.
