No, 21 gal.

I've got about 2500 miles on my 4x4 auto so far. I drive around 50 miles a day back and forth to work. A little highway and the rest streets with minimal stop lights and speed limits around 40-45 MPH.

Last 2 tanks were around 21 MPG I don't drive that hard, but drive like Granny either. Overrall I am quite pleased with the mileage as my 99 J@@P Grand Cherokee ( 4.0L 4x4, auto) got around 19. and our 03 Envoy XL 4x2 got around 18MPG in the same driving conditions.

The X is a much better vehicle all the way around than the prevoius 2 vehicles.

20mpg on the last tank. 95% city driving and shifting between 2000 - 2500rpm

17 mpg on the last tank. All city driving, shifting at 2000-2500.

I went on a 133.6 mile round trip today. Only 36 miles of it was "freeway". The remainder was city driving and county road/state highway with construction delays. At my turnaround point it was gravel road and pasture complete with mud and meadow muffins. I had topped off when I left and topped off upon return. I went 133.6 miles and used 6.376 gallons of Chevron 87 octane. That comes out to 20.953575 mpg. Close enough to call 21 mpg.

That was with the A/C going and moderate wind.

I drove between 60-63 mph on the highway stretch which is 18 miles one way. About 1/2 way through it, I notice a pickup blows by me at 70-75. At the end of the highway stretch there are a series of traffic signals. At the first light it is red and this same pickup was only two cars ahead of me. We were at the intersection at the same time but I used considerably less fuel than he did getting there.

Compared to most of you, I am old. So you would drive by me and think look at that old fart going so slow. Its not because I can't go any faster, I don't want to. It doesn't take me that much longer to get there. It costs less and is safer. I haven't had an accident or ticket in 10 years.

In the US, approximately 42,000 +/- (http://www.cbsnews.com/stories/2004/08/10/national/main635233.shtml) people a year are killed on the highway and most are attributed to speed or speed for conditions. Compare that with the number of active military deaths in 2004 which was 1887 according to http://web1.whs.osd.mil/mmid/casualty/Death_Rates.pdf.

I'll go a little slower and live a little longer and spend less.

Kind of like the two bulls at the top of a hill. The young bull looks down in the valley and sees a bunch of cows. The young bull says, "Let's charge down there and get one of them cows!" The older bull says, "Let's walk down there and do them all."

Make sure you check your tire pressure.

Mine were all around 26lbs.... I then slightly overinflated to 33 and got 2MPG - I'm averaging 19 in mixed City/Highway driving. Not bad...

Invest in a good tire gauge and go with the factory recommendations. On my O5 it should be 35 and that is what I go with.

Well, for the pre-'05's it's 30lbs - and you do get a slight benefit from a slight over inflation, even if you do sacrifice some ride quality.

I just filled up my 3rd tank, my first tank averaged about 16.3 miles per gallon. I installed my loadwarrior and bike rack before my second fill up (loadwarrior, x-towers,crossbars and 2 bike racks on the roof) my mpg dropped to 14. I am now getting worse mileage then I was in my 2001 Xterra. I know its too soon to tell but does anybody have any recommendations other than tire pressure and air filter. I hope this trend isn't going to continue.

In the paper over the weekend they were talking about the high price of gas and what people can do with their cars. Apparently there was a study that was just done that came to 2 conclusions:

1) don't gun it at the lights, take your time to get up to speed.
2) ac or open windows, does not really matter

I think running AC the whole trip is gonna hurt your gas milage. Most of the dealer MPG sticker specs are without AC running I think. Corect me if I'm wrong.

Per the owners manual section 5-18 "When cruising at highway speeds it is more economical to use the air conditioner and leave the windows closed to reduce drag"

I have read in several places they say the wind resistance from driving with the windows open is worst than running the air conditioner since the new ones are so efficient.

jsut filled up my second tank in my new 05. will check out my mileage, but in the meantime, does anyone know if a good catback exhaust will increase gas mileage? i seen a few advertised (one of the few acessories available for the 05 ), but not sure if its worth the price or if it will void the warranty

euphoria-

There have been a few threads on this and I think the general consensus is that a catback and even intake won't help that much. If you want them put them on but the likelihood of saving enough gas to pay for them is a very long way down the road if at all.

I guess I can't complain. My first fillup was 17.61 MPG. That was in mixed driving with the A/C running. I had a 2000 Nissan Crew Cab, and the engine was tight initially too. Mileage improved with time with that truck. I expect the same with this vehicle. I hope to be breaking 20 MPG in a couple months...

I have calculated this with both 50% Hwy/50% City, 25% Hwy/75% City, and mostly city, and I ALWAYS end up right at around 15.5 MPG. Granted, my "city" driving involves sitting in still traffic, moving for a quarter mile, then sitting in traffic again. And, all my city trips are 3 miles or less. Super short, super trafficky, and always with the A/C on. I guess that's why I'm not seeing more than 16 MPG.

Also, I like to gun it...but when she was being broken in I took it easy. I have noticed no difference between gunning it and taking it easy off the line. Maybe because my mileage is piss due to my short city trips, I guess it doesnt matter if I take it easy off the line...

If my trips were all like this, I would use a bicycle. You aren't driving it far enough to get it warmed up.

I just broke the 2K mark on my X and have noticed that the MPG is increasing.

As for A/C or Windows I believe the TV show Myth Busters ran a show to test this theory.

... but they did the test at less than hwy speeds, and had skewed results because of it. I watched that show. Like to see them do the same test again, but at 70-75 MPH.

This thread got me thinking... I have about 6500miles on my X and so far have been averaging 16-17 in city and 17-18 in highway.

I just did a 600 mile trip including driving in the Sierras for 3 hours (lots of up and down). I kept the speed to 70mph the whole way and amazingly got 21.9mpg! I never expected that much of a difference. I have done this exact trip a few times in the X and every time I averaged about 17.5mpg, but doing 75-80mph. This made about 13 minutes of difference each way vs. about $19 of gas.

Since this trip, I have been babying it driving around town and I am getting about 21-22mpg in a mix of city/highway driving. I guess this is where stopping to be a leadfoot pays off big time

Now only if I could control my urge to rev it up

My commute is about 1.5 miles and it takes me a few minutes. Any time I go to the other side of town, a couple mile drive takes 10-15 (because of traffic and lights) so on those drives it probably warms up a little more. I agree with the bicycle comment, but I don't wanna show up to work all sweaty (it's super humid here)...

Also, maybe I should stop driving 80 on the highway? I think I tried 70 and it didn't help - but I kept going up to 80 to pass people. Perhaps I should try keeping a steady 70...

I'm right there with you, I just popped up to 19MPG this evening. It is difficult, but I managed to retrain my driving habits and lay off the gas. Every thing I do now is smooth and easy. No hard accelerations unless I really have to do so. But driving like this now makes me appreciate the feel of the truck even more. I feel in tune with it more and more. It's kinda weird......

OK, I've had my X-Terra since April, and just turned 13K on the odometer. Ive gotten about 20MPG since the 2K mark, and most of my driving is freeway. I get about 350m per tank, and put just under 18gal in at a time. I upshift at 3000rpm, and down shift at 2000rpm, leaving me at 2500rpm in 6th gear doing just under 80mph. The AC is blasting when required because I agree that the wind disturbance caused by open windows will exceed the draw in HP of a AC compressor. I am happy with the mileage I get, and 2 of my co-workers drive H-2's and have had to park them due to fuel cost.

I just checked my mpg city trying to drive slow to get a good result. 15.6 Not so good. Some of this may be the 285 75R 16 BFGs I put on instead of stock. Oh well I think I'm going to drive it the way I want which is with a little attitude oan F**k the mpg. If you can't drive the way you want then get another vehicle.

Cheers

WEll, i have about 850 miles on my '05 X and the computer gauges at 16.3mph. How does that work anyway? Im too lazy to open up the manual. Thanks.
