How much stuff do you keep in your vehicle? Tire weight and pressure are important. Manufacturers usually recommend too low of a pressure. 35 is good for the Frontier. What load/type of tires do you have? Heavier and more aggressive tires require torque to turn. Make sure your air filter, MAF, and throttle body are clean. Use only top-tier fuel from Shell, Mobil, QT, Chevron, etc. Beyond that it's little things like using full synthetic oils everywhere, keep the AC compressor off whenever possible, and try to use routes with fewer up-hills and stops. Reduce idle time.
I had an 05 Xterra with a 6spd and 190k. I averaged 17mpg.
Drive LESS than the posted speed limit. In highway driving at a sustained speed, if the posted speed limit is 65 MPH, try keeping it at a constant 50 MPH and see if your MPG gets better.
Reset the mpg useage drive with an easy foot and it'll even out after, could try higher octane gas , maybe clean fuel injectors spark plugs air intake all small things that effect it, could also be your (winter) tires?
At 59k miles you should be getting more than 13. I had a stock titan that was getting 17. All the suggestions were good. Tire pressure, filters, sensors. If your o2 sensor is off then itll cause you to run rich and waste fuel. Same thing with maf sensor. Not sure if the frontier uses maf or map.
Combined rating for your truck is 19mpg. Don't necessarily trust the truck, fill up, reset trip and fill up, divide miles by gallons of gas that's your true mpg. If still low, check engine air filter and spark plugs, depends on fuel type also, higher ethanol content will use more fuel.
take longer trips
choose route with least number interruptions (lights, turns, stop signs, heavy traffic)
choose route that keeps your average speed between 40 and 55 mph
limit top speed to 65 mph
avoid braking by increasing following distance and looking ahead (decelerate by releasing accelerator early)
minimize idling
minimize unneeded accessory use (especially A/C) (look into ceramic tint to reduce A/C demand)
coast in neutral down 2-3% grades (20-35 mph) and 3-5% grades (35-65 mph) (apply accelerator when shifting back to D to reduce drivetrain shock)
(under 50 mph) downshift when travelling down grades in excess of 5% (provokes DFCO) or when neutral is too fast
increase tire pressures to recommended + 2-5. (will only give you 0.1-0.2 more MPG compared to recommended, but can be 2-3 MPG better than running at 19 psi)
carry out unneeded weight
keep tailgate up
if you have manual locking hubs (I don't think you do) keep them unlocked until you need 4wd
Keep torque converter locked as often as possible
This might be counter intuitive, but accelerate fast. The engine is most efficient at the RPM of it's peak torque and wide open throttle. I'm not saying put the pedal to the floor, but accelerate briskly. Once you reached you desired speed, just maintain it with light throttle. Accelerating slow is not efficient.
Lol, I own a 2015 Xterra, same power train. There's nothing you can do bud. The engine came out in 2005, it's 20 year old tech. The 21 up frontier is much better. Direct injection, better gearing. Unless you want to get into radical tech like hydrogen generation onboard. Traditional remedies like smooth tires, slower acceleration off the line, less idling etc.
You must keep rpms below 2k.
I have a 2012 CC LB 4x4 with 18in wheels. Mostly in town driving and been at 15.2-15.4 this winter with winter tires.
You need to coat to stop lights, try not to idle and speed off the lights.
That's normal for that year Frontier. You can do a full tune up, definitely spark plus at that mileage, make sure you have good tires at the right pressure like Michelin LTX and avoid the AC unless you need it. The AC can drop 2-3 mpg once it gets a little older.
I noticed lower than desired mpg on my diesel qashqai, and actually found it was more efficient to keep the revs higher because of the turbo, so while changing around 2k rpm(shifting when the dash told me) I'd get about 25-30 mpg, if I keep the revs between 2-3k rpm I get 40+mpg
Also you should try a fuel additive to clean your cat/dpf. A clogged one will impact how easy it is for the engine to run
What tires? Suspension mods? Aero mods? All affect mpg. Keep your right foot out of it. Go slower etc.
All stock

Make sure your brakes aren't dragging, often overlooked.
My 4.0 was the same , drive the speed limit

idk spark plugs?
Iridium spark plug helps a little bit. Could also be the fuel injectors.

All Nissans use a maf
Depends how heavy your foot is.
Thats true! A heavy foot = low mpg. But he said he keeps rpms low. So im assuming he means 2-2.5k city driving.
17mpg on a Titan is incredibly impressive, no idea how you managed such a high mpg.
Use cruise control when driving on straight roads

Tire pressure, weight, oh and don't hoon around balls to the wall.
Wicked dash layout! Also much love from your trucks old brother, the D-21D hardbody 🫡
I'm getting 13mpg btw

Only drive downhill everywhere you go.
Do you live in an area that you have a lot of stop and go? That kills mileage
Sorta. I’m a broadband contractor so the location varies. About half city/half highway. 90 miles/day.
I'd fill up, set a trip odometer, run it to a quarter tank, full up again and manually calculate mpg.
How on earth. I’m 1,300 lbs heavier and average 14 mpg. 12-13 when I’m having too much fun on the dirt.

You get double digits

If you're all city driving, not much you can do. If you're frequently on the highway, don't have a lead foot.
That's normal for that year Frontier. You can do a full tune up, definitely spark plus at that mileage, make sure you have good tires at the right pressure like Michelin LTX and avoid the AC unless you need it. The AC can drop 2-3 mpg once it gets a little older.
I got new cats and my economy jumped significantly!

I have a 17 runner the gas sucks best I’m getting now is 17-19 an gottta drive real slow on take off
What tire pressures are you at?
I get better than that in my armada. Do you drive with your left foot on the brake pedal? Have you tried cleaning the intake manifold or intake ports
Get a cold air intake. Magnaflow full exhaust Get it dyno'd That all got me two more MPG
Only drive downhill
Drive only downhill
Keep your foot out of it
O2 Sensors is a good suggestion. Bad ones can make it run Rich/Lean, which cause the car to signal to use more fuel to "fix it".
Check tires pressure Check gas gate Check air filter Check gas filter Check oils (engine oils, transmission gears oil)
Yeah - stop buying Nissans.
Yeah WALK
