Getting horrible gas mileage, gas around here is $2.33/gal and I can put in about $16 worth and only gets me down the road to buddies house and back and already on quarter tank.
Bad gas mileage, any fixes?

...as well as cruising speed. Guesstimating that closer to 55-60 mph will glean enhanced fuel economy.

I've been babying mine and have averaged 17 around town. Mostly going about 50mph. Plenty of stop and go and hills too.

Its a 2002 Nissan Frontier Desert Runner XE 2wd Automatic V6 about 155k miles.
I haven't done like an accurate test on how many miles per gallon I get, just seems it runs out entirely way too quickly. Like going only like 10-16 miles and using a good bit.
Pretty sure the tires are at the correct Psi, haven't had a tune up in awhile.

also, $16 means you are putting just under 7 gallons of gas in the tank, so, yes, you will be back to 1/4 tank in what seems like no time.

I keep wondering when someone is going to do a swap with the Australian diesel counterpart Navara engine. Ive seen them for sale on eBay, god knows what shipping from Australia would cost.The VG33 isn't known for great gas mileage.
As a consolation, it is pretty gutless too
A 4-cylinder diesel and ZF 8-speed transmission would do wonders in one of these trucks.

Oh, I'd love to see a diesel in a U.S. market Frontier. Maybe in the next gen...The VG33 isn't known for great gas mileage.

I saw a video from tfl truck where Nissan put a diesel in the current gen frontier. Never made it to production obviously and they wouldn't release specs to the guy from tfl but he was driving it during the interview. So if you've got time and money you could always do an engine swap and drop one in there but it isn't gonna be cheap.

the following video is from 2015 and they put a diesel test engine from the nissan titan into a plymouth road runner, though i will say i never knew nissan sold a diesel titan here in the states
I think it was a development engine that the Dirt EVery day guys used in that video.... That being said, The 2017 Titan now has a Diesel in it.
To the original poster, you have failed to include details that are relevant and prevent us from really helping or confirming what you suspect.
Some great info would be... Tire size, any mods done to the truck, are you doing maintenance on it regularly or just beating on it and *****ing about unknown factors????
For reference. My 2013 got 21 MPG pretty much no matter what I did and as long as I loaded less than 600 pounds in the bed. On rare occasions I would get more but I could plan on no less than 21 MPG. I switched tires lately and put a lift on. I knew I was going to get worse mileage and honestly its a little worse than I hoped for but the things we do for a cool looking truck. I dropped to about 17 mpg with a simple change of 285/75-16 tires, so I understand your concerns a bit. Now having said that, you can look at things to improve, such as tire size, driving style, etc etc, but we can't help if we are guessing stuff all the time.
FWIW I will be swapping back to a 265/75-16 to get some mpg's back in the not too distant future but I am in no huge rush right now and the only reason I am OK with that is becuase I have another project truck that I'll swap the larger tires on to and I will probably never really care what kind of mileage I get out of that truck because it's my Zero f**ks truck and it gets a pass as long as its got the power to do what I want it to.

I've been getting 13.8 according to my computer replaced spark plugs and getting 14.6 so I'm going to do O2 sensors next then fuel filter and see where that gets me.
On a side note Nissan did develop a frontier with a cummins 2.8 turbo diesel and asin 8speed tranny out the dodge eco diesel. But as always never made it to production. Although cummins is releasing a version of that as a crate motor soon check out the link. I've been scheming of ways to get a diesel in mine since I had my first 2nd gen frontier
