What's the cost difference between the 3K and 5K oil changes? Is it with conventional or synthetic oil? If its not much just keep going with 5K. Following the regular intervals stated by Nissan are your best recommendation.
I've run Castrol Syntec 0w30 for 16000kms and it came out orange brown still! A good indication to find out if your oil needs changing is a visual check, so if its below the minimum mark and black, change it!
