IMO, if you are using full synthetic oil and changing it every 3K miles you are just wasting tons of money! Stop right now. If you use a full synthetic, which is great to do, you can safely change every 5K at a minimum. Even Infiniti only recommends every 3750. Personally, I'd recommend changing your filter and topping off after about 5K and then oil and filter after another 5K but that's just me and my personal experience with Nissan engines and synthetics.
Royal Purple or Mobil 1 it really doesn't matter as both are high quality fully synthetic oils. Any quality synthetic will work.

agreed... Blackstone labs always shows full synthetic and synthetic blend oils (i.e. mobil 1) lasting upwards of 10,000 miles, and still a lot of life left past that.
the dealer will NOT replace with any kind of synthetic (you MIGHT be able to get them to if you have a friend in the service dept.) they will just change it out with regular...go to a shop or you can even go to walmart (if you trust them with your car 
) and tell them you want mobil1 or whatever and have them do it. the synthetic oils are SOO much better for your engine in the long run

Im at around 18,000 miles on an 08 coupe, 6 speed and wanted to switch to synthetic. Can anyone tell me the exact name of the synthetic oil I should buy. Infiniti wont tell me cuz they said they dont recommend synthetic. Thanks

Select only engine oils that meet the American Petroleum Institute (API) certification or International Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils have the API certification mark on the front of the container.
