Here's a glimpse at what I've been getting for fuel economy. It's not amazing but it's quite a bit better than my last truck (2010 Ranger FX4, 4.0L V6) and I'm satisfied with the numbers. I think have a heavy foot so lots of you could probably do better than what I'm seeing but with 310hp and 281ftlbs and I really enjoy driving this truck. Nissan rates this truck at 12.8L/100km for city and 9.5L/100km for highway (combined=11.2) which is obviously a fair ways off from my numbers, but I expected that since I live in a mountain valley and I spend at least half my driving time going up hills (no, driving down the same hill doesn't balance it out to be the same as flat drive) which blows fuel economy all to hell in a hurry. I use my old Ranger as a comparative tool and where I'm seeing 16ish in the Frontier I was seeing about 19-20 in the Ranger.
Here's a spreadsheet of my fills/kilometers below but basically I'm averaging about 16.6L/100km (or 14.2MPG.) I've got one or two more fills that aren't loaded into the spreadsheet right now but they're right around the average. This is not good scientific method because I'm just logging the kilometers I just drove and the amount of fuel consumed to bring the tank back to full so there's at least a dozen spots where accuracy is being lost but I think it's a fair method to use as a truck owner that just wants some ballpark data..
The next couple of fills that I have to input will include more cold weather and snow driving (and doing doughnuts in the parking lot at work..) so there will be more idling and more use of 4WD to analyze and compare, this segment of the numbers is primarily "warm" (read: above freezing or only a few degrees below) weather and no 4WD use.
I missed 2-3 tanks when I first got the truck because it was a whirlwind week of picking it up and immediately packing for a weekend road trip but apart from that, this is a complete running log of every liter of fuel I've put in and every kilometer I've taken out.
I always track this info on all my vehicles but with this one I'm especially interested to see what happens to fuel economy when I put my 255/80/17's on with the lift kit in spring. I know it'll be a hit but I'm curious to quantify that..
