2nd the thought on the thermostat. Should be a 195. Also, a 15 minute drive, even mostly freeway, is a short trip. It is just getting hot when you stop it. Perfect setup for blow by buildup in the oil. You want the oil to get hotter then 212 so any water in the oil boils away.

Make sure the PCV valve is working and the vacuum port for it isn't plugged.
