2018 model hemi operating temperatures

So if 5th gens have oil heaters, is there any point in running a 180 or 190 tstat? Would the heater think that's too low and continually heat the oil? Or do we just turn that heater off.

It's not really a "heater" in the sense of adding extra heat to the engine... it's a heat exchanger that speeds up the process of bringing all the different parts of the engine up to the same temperature. The coolant in the head gets hot faster than the oil in the pan so at first it heats the cold oil. Then helps prevent the operating temperature oil from getting hotter than the coolant.

This means everything expands and contracts at the same rate, and undergoes fewer total thermal cycles over their lifetime and this dramatically reduces wear and the rate at which leaks develop.

Disabling a feature that prevents leaks, reduces wear and improves fuel efficiency doesn't sound like a real smart move to me but hey knock yourself out?

That makes sense, I'm familiar with how a heat exchanger works so that answers my question.

I'm not sure anybody is suggesting to disable something like the heat exchanger, but I don't see any problem with putting in a 190 tstat to make the entire engine run cooler, especially if you tow in the summer. I'm sure that can only increase the life of your engine.
