Changing modern synthetic oil every 3-4k miles is just plain uninformed and a waste of money. Unless you are tracking your 370z, there is no reason to do this.
A good oil and filter will hold up for 5-7.5k miles under hard street driving conditions provided you let the car warm up properly and don't excessively idle the engine.
Go look at some oil reports on bobistheoilguy forum and you will see there is absolutely no need for these non-sense recommendations.
I change my tuned 15' Nismo oil at around 5k-7k depending on how hard I've been driving and the temperatures it's been experiencing. I used to use the magical Nissan ester oil until about 35k miles, then switched to mobil 1 and I don't know any excessive VVEL noise. Speaking of the Nissan ester oil, that is not a full synthetic -- so if you are running that I would change it at 5k, but it's not worth the price.
To end things, the oil filter does more of a job then the oil brand itself. Make sure you get a top of the line filter and you'll be insured that all the garbage is sticking inside there.
The same gentlemen who said change your oil at 3k here, told someone in the classified forums that his v2 nismo front wheels were out of specification. A simple google search would have shown him he was incorrect. Let's do a little research before recommending people bad advice.
