I ran across this video on YouTube regarding oil change interval recommendations from a past Nissan GTR engine production leader. The short take is that one is better to use inexpensive engine oil and change it every 3k-4k miles than use more expensive oil with a longer change interval. At a 3k-4k change interval the oil used doesn't make a difference other its viscosity rating depending on seasonal climate conditions. There is more info in the video about oil degradation and oil contamination.
