Gas mileage is concerning..

[smurraybhm]

15.9 mpg strictly city streets on commute, totaling 10 mile RT. lucky to hit 40 miles an hour for a few seconds. At 3700 miles after buying in January - low mileage due to short commute. This mileage isn't any different from what I was getting with the Ridgelines I owned before seeing the light.

Cruise Control works wonders- Yesterday I drove from Orlando to Miami with a 1400lb load and she did 22mpg at 73mph.

Buys Jeep pickup with the aerodynamics of a brick factory. Complains about MPG.

Every response here will be pretty subjective. Different drivers, different driving styles, different roads, elevations, areas, conditions, weather, etc. More important different vehicles. Lifts, tires, loads, etc.

Check out fuelly.com for some stats.

When I see people who claim they get 23 mpg highway on 37s with the Pentastar. I just laugh. There is no f'ing way, unless you drive 55 mph on a runway.

The easiest and cheapest way to improve MPG is a driver mod. Change your driving style.

My work is 66 miles away from my house and 98% is either clear highway or interstate driving. I drive in to work 2 - 3 times a week.
I've performed a few tests at different speeds and driving style is certainly a major contributor to what you're getting for MPG.
This is what I have found on my stock JT, most always using the cruise control...
25-26 mpg at 66 mph
23 mpg at 70 mph
20 mpg at 74 mph

When the wife rides along, she'll run around town to do the shopping while I'm at work and when she picks me up for lunch the mpg has usually dropped down to 17 or 18 mpg, so I'm figuring she is really getting more like 13-15 mpg with her heavy foot.

Don't know. I get about 17.5 around town and high 19s on longer highway drives.

Let me start by saying I don't own a gladiator yet.

But it seems that most people get 20ish on the highway and 17ish around town.

But if you live in an urban area, your fuel economy can be even worse.
I recently moved to a pretty urban area from a rural area.

My mileage has decreased significantly.
My car always got 26 mpg on road trips and 21 around town.

Now that I'm in an urban area I get 18 mpg.

So I just want to hi light that there is a big difference between suburban "around town" and urban "around town".

This makes total sense. I drive 75ish on the highway. I get about 26 mpg.

I recently went with a friend to pick up a new boat. I ended up following him home for 100 miles on the highway. Because he was a bit nervous towing the boat, he stayed between 50 and 55 mph.

I got 32 mpg on that trip!!!

I have a stock Willys (manual) with abut 2500 miles. It has averaged between 15.5 and 16 mpg. The thing I find curious is the great disparity among the responses. I understand driving conditions and driver input matter but some getting 14mpg while others getting 22 mpg seems like a huge disparity and that is among the stock Jeeps.

I get it's a Jeep and personally have stopped thinking about it, but 15.5 mpg really sucks.

It's basically a non-aerodynamic brick. I get about 14.8 for in town with 4:10s and 37s. You want good gas mileage on the highway, learn to tailgate. Seriously. Letting another car cut the wind for you will be a dramatic increase in gas mileage. I'm guessing some of you with your high mileage numbers are either not going over 60, have a diesel, stock tires, or just following traffic closely. I get my best gas mileage with bumper to bumper traffic on the freeway regardless of how fast we're moving.

Everyone seems to vary by how they drive it, where they drive it, and what they've done to theirs.

When I first bought my '21 JTO in June I was averaging around 20 fully stock back and forth to work. So around 20 miles each way mixed with highway and city. After I put the 33s on my mileage went down some too expectedly. I routinely average now around 17-18 with the same mix of highway and city even after recalibrating the the BCM for the tires.

The sweet spot for our JTs seems to be cruising around 55mph in 8th gear. Not a problem if you live in a state where that's the max speed limit still on some highways. Here in Texas our highways our mostly 70 and 75 along with some remote portions being 80 or 85. Driving out to BBNP in West Texas at 80mph for almost 5 hours I was averaging around 15-16 on the highway.

Not me...I can't stand tailgaters and usually leave about 6 - 10 car lengths in front of me while on the interstate.
It just seems logical, that if you are tailgating, you are using more brake and gas to maintain your position, whereas if you leave ample space in front of you, it provides a greater margin to allow for coasting where brakes are not necessary.
Sure it's a brick on wheels, but I would wager any day of the week that any benefit you are getting from wind drifting the guy in front of you is lost and outweighed by the additional braking and gas.

The force of the wind is strong on this one Yoda. I’m about the same.

So true, and I do not drive it to promote good mpg, I just drive it to enjoy it

I use cruise as well, but when its hilly and you have to drive at least 80 to keep from getting blown of the road, I’m not sure how much mpg the cruise actually gives you

Thats as far as I read.

Well then you are missing some fan effing tactic wisdom and experience.

psst - the gladiator behaves like everything else on the road when it comes to aerodynamic and rolling drag.

It's horrible anywhere with hills, like my area. It uses the brakes going downhill and feels like it uses 100% throttle uphill.

It doesn't bother me enough to turn it off but I am sure I could do better myself.
