An engine that doesn't get to operating temperature will have accelerated wear. Modern engines are running hotter than 180. 200 would be better for wear, but clearances have to be tightly controlled to run there and also use aluminum parts.

I've noticed my 61 F100 has a tendency to run cool. But it is a 6 cylinder version of the 53 Ford tractor engine with a big radiator. Designed to idle all day in Texas summer heat on the farm.
