The higher temps are probably due to a fresh engine with good tight bearings. Also, oil is always going to run a little hotter than the coolant, since the oil doesn't have a radiator to shed excess heat.
Personally, I wouldn't like to see sustained oil temperatures below 212F. You have to remember, that the oil also has to boil off any moisture. Also, moisture is a combustion byproduct. Where is it going to go if it gets past the piston rings? That's right....
I think it's doing just fine the way it is. Most modern quality engine oils have a flash point of at least 400F anyway.
Also, aren't there additives in modern oil that only work at higher temperatures, like moly?
This is my theory anyway. Maybe I'm way off, so dont take it as gospel just yet!
