FZirst of all, the color of oil is NOT a good indicator of any issue.  If you had the oil tested, how much fuel was in it?  Did the viscosity drop out of range for the oil you were using?

What are your driving habits?  Do you do a lot of short trips (under 5 miles) where the oil never really warms up?

I would like to see the data from your oil analysis.

I agree.  1.6% of fuel in the oil is high.  You should definitely talk to a Nissan rep.  Your mileage is about right for around town driving.  It may be that you are getting too much fuel on cold startup.

However, if you take this truck out and drive it 50-60 miles, you should burn off the fuel in the gas. Did you get any wear metal numbers with your oil analysis?  If iron, copper, lead and aluminum are higher than normal, this can be the result of diluted fuel but on an engine as new as yours, you are still going through break-in and metals will be higher as a result.

Let us know what the Nissan rep says when you talk to him.
