Get the picture?
Coolant temperature should be in the middle of range and be relatively stable.
210 is very much in the middle of the range. 230 is pushing it and 250 you'll be lucky if its not boiling (depends on pressure and mix).

Running too cold means the cylinder walls are on the cold side and so is the oil. I like to see at least 190 once its warmed up. Sometimes in winter that's tough with a 180 thermostat.

I'm more of the school of heat kills...
Now I wouldn't want to go run in my car at 80 degrees or anything like that but if I could keep my car at a hundred and sixty-to 170 all day long I wouldn't be freaked out about it.. it's my understanding that he breaks down the viscosity of the oil? Just like your transmission the cooler you keep it the longer it will last.. (I was talking automatic there I don't have one)..
Just food for conversation not trying to argue with you...
