They definitely run hotter because of emission laws.

Hotter is harder on gaskets, harder on oil, harder on the transmission, and harder on every underhood component. Heck everything non metal, from the paint on the hood to wire insulation is aging/curing at a rate determined by time and temperature.

I don't think it makes my engines last any longer, but always go to 180/190 stats to extend the life of everything within 2 feet of the engine.

However ratmonkey's comment about all engines ultimately reaching the same temp is true with mechanical fans or smallish electric fans. But with a killer pair of electric fans and a robust cooling system you can often keep an engine close to thermostat point for hours on end, even with a cool stat.

This winter my motor would eventually get near operating temp but on the highway it was pretty low like 160* sometimes. Now that it has warmed up it's right around 190-200. I have a 180* stat in there and the trans is bypassed so it doesn't get heat from that. I think I am going to try a better brand stat though. I have a fail crap I think.
