Well, here in college now, I've realized how most students here operate their cars/trucks.
The vast majority of students live off-campus, but most only a few miles away. Four or five days a week, they drive a few miles to the parking area, and then drive a few miles back to their house/apartment.
Now, while the coolant temperature does get to it's thermostat-open point, I seriously doubt the oil approaches any temperature that will burn off contaminants.
Now, in conditions like this, I'm thinking that the most desirable trait of an oil, above everything else, would be one with a high total base number, to help neutralize the acids/contaminants that would accumulate (And continue to remain in the oil until the student took a long drive somewhere).
Please shoot some holes in my argument.
