During the entirety of my Z ownership, I've used Mobil 1 5W30 and Nissan OEM oil filter and have done change every 5k miles (that might even be too often). But with my car being out of warranty and me being a bit more environmentally conscious, I've decided to switch over to Mobil 1 Extended Performance rated for 15k miles and/or one year oil changes.
My plan is to use EP at my next change and 10k miles later, send a sample to Blackstone for UOA (I'm confident that the EP will last at least 10k miles). Depending on the results, I will either go the next 5k miles before another change or change it at 10k (many people out there using EP are opting for an early 10k miles changes).
If anyone is curious, I will post on this thread the results later.

Lastly, the extra protection additives in EP over regular Mobil 1 isn't just a marketing gimmick, someone did an analysis on virgin EP and confirmed that there are more additives in it over the regular stuff.

They also said that they guarantee that EP won't ruin your engine with the longer interval and that the oil filter doesn't need to be changed until the oil does as long as it's a high quality filter (they said a Nissan OEM filter should be fine).
