Having said that, in any model range, there are some vehicles that get great economy and some that get rubbish.
The ZD30 is a prime example, some people on here could never get better than 15, most get around 12.5 and a few get 11's.
I would do two things, first I would check the accuracy of the Odo over a known distance/GPS and second I would check that the tank actually takes what the LPH says and not noticeably more.
That LPH figure from the onboard Computer isn't always correct.
If the LPH is, say, 13 and you drive a genuine 300 K's after a fill and yet the tank accepts 35 not 30ish then the vehicle is actually using what Nissan claim.
If the dash figures are accurate then, well done, you lucked out in a big way and don't let Nissan do any ECU updates/remaps
