  • 2006 Offroad Automatic driven 2175 miles. Overall 19.72 mpg. Best 23.61 mpg, Lowest 17.1 mpg (on first tank). Just FYI for those shopping and wondering about real numbers. 75 mph interstate driving across Wyoming yielded 19.2 mpg, 40 to 55 driving through Yellowstone and the Teton area yielded the 23.61. :)

    Just bought my S 4x4 automatic Wed. night, was out the door on the highway Thur. night for a road trip, got 20.7mpg w/ac running. Since the engine hasn't been broken in yet I thought this figure was OUTSTANDING! I kept changing speeds between 65-75 to help with break-in, but pretty much stayed in the 70-75mph range, only had to step on the gas a few times for passing, pretty much smooth sailing the whole time. 332.5 miles, 16.03 gallons, if this holds up until my engine breaks in I'll end up looking like Joan Rivers after a face lift from my ear to ear smile :P

    Just purchased a used 2006 S 4X2 with 12000 miles. On the ride back from the dealer (which was 200 mi away) I averaged 22.7 MPG. Most of the drive was on the interstate (in Florida) with the cruise set at 79. In town I averaged 19.8 MPG. I just recieved a K&N panel filter so we'll see what kind of difference it makes.

  • I have a 2005 S, 4x4, 6 spd. Just finished a trip to Houston from Tulsa. On the return leg I gassed in Sherman. Got back to Tulsa and refueled. Drove 199.5 miles on 8.544 gals. Mileage was 23.349. My speeds were from 45 to 50 in the orange cone zones to 78 in the 75 mph zones. AC was off. My X has 14K miles, Amsoil 5W30 oil, Amsoil gear lube in the trans,an Amsoil air filter and a Magnaflow cat-back exhaust. In town the wife usually averages 16+ with alot of street driving. On a trip with the AC running and doing about 80 mph I have averaged 21.22 mpg.

    thinking of buying an 03 4x4 se and was wondering if the 14 mpg mark is true? I plan on putting a cold air volant and a magnaflow cat back or the gibson (can anyone recommend any others)and ditching the fan clutch for an electric unit any one have any feedback I have seen numbers as high as 19 but as low as 12 in the edmunds review but that was on a stock 00 My 2000 explorer 2dr 4x4 gets a solid 19 average with 130000 on the clock
  • I have seen this discussed, but I have never gotten a "difinitive" answer.
    Can the Xterra and Pathys run OK on reg gas?
    I assume the HP may be down a touch,
    has anyone been able to test it both ways, and get real world #'s?
    Is it hard on the engine?

    Traded in '07 Nitro POS dissapointment. I did get up to 23+mpg on I-25 between Denver and Pueblo Colorado..It didn't make the trip back, got traded in for an '07 SE XTERRA new off the transport truck. 18 mpg at first and then improved to 21.8 generally hiway mpg by the time I got home...I am now up to 146 miles on this new unit...I'm very happy and feel it will improve on mpg.. If I don't drive like an idiot which I don't..

    I have an 06 S 4x4. I put a K&N cold air pipe and filter on it but everything else is stock. It has 20K for mileage. I get 23MPG on highway trips @ 65-70MPH. In town I get about 18-20MPG. Great little truck with lots of grunt. Have thought about a Cat-Back exhaust- any ideas??
  • tinycadontinycadon Posts: 287
    Just took a 400mi trip, turned on the cruise control, set it at 70mph, and got 23mpg! That's some pretty good mileage from this bad boy.
  • I guess I should have bought an '05 or newer, 'cause the best I ever got in my '04 was about 16-17 mpg.
  • 2006 Xterra SE. 17.8MPG in city (by internal comp) and a satisfying 23.5MPG on long trips around 70-75 mph. In my experience, the gas mileage deteriorates rapidly over 70mph though. When I cruised at 80 mph i found I was getting more around 20.1MPG (ouch!!). Just puts some aerodynamics into practice i supposed.... Having a flat front end does not help your mpg. :)

    I am seeing all these posts of the Xterra get 18 to 23 MPG. I bought a 2008 OFF ROAD model which has transfer case, locking rear differential, hill descent control and other mileage robbers the other models don’t have. I get 11 MPG on dirt road and 15 on the highway. I live in the Arizona hot desert rural community so I don't get city driving. I never had a six cylinder get such poor mileage. Every thing else I like. Runs good on the highway. Good suspension and steering for being a true off road machine, I say off road because it truly has a truck type ladder frame... only Toyota FJ Cruiser and the Xterra have ladder frames in SUV’s. The question I have, comparing apples to apples does every one with the OFF ROAD Model with the 4.0 liter 5 speed automatic get such poor mileage?
  • Well, on our first tank of fuel with a 2008 Off Road auto we got a whopping 14.8 MPG. All city with a pretty light foot. I guess time will tell how accurate some of these other posts are. Granted the truck only had nine miles on it and I know it will loosen up...but not sure it will loosen up THAT much!

    I have over 2200 miles now and am getting 16.5 to 17 on the highway. I believe the OFF ROAD model doesn't get as good as mileage as the other models do. I can't get anyone to admit it. Too bad I traded a 3/4 ton, 4x4, 4 door Dodge pickup that got 18 to get better fuel mileage in a smaller vehicle

    :lemon: :blush:
  • I will be interested to see how this turns out. I never expected to get great MPG...with an advertised MPG at 14 in the city I guess that the sticker was pretty accurate. I am not sure how some of these folks are getting these high numbers at higway speeds. I also have an 03 Lexus IS300 w/ K&N and Borla cat-back which got me 24 MPG on a 952 mile road trip last month. Smaller motor, more aerodynamic, lighter and yet it gets the same MPG as an some folks Xterra.

    The government MPG says 16 City and 20 on the highway. I was told by the dealer to expect better. My 1999 Jeep Cherokee with 4.0 liter (straight six injected farm tractor engine technology) auto with 3" lift (to get over the rocks) get's 22 on the highway so I know its not just being an off road SUV. I am starting to believe they changed something for 2008 off road? Dodge kept doing this with the Cummins diesel engine so I bought an older one to get good mileage. The Cummins is such a good engine they kept making it bigger more horsepower now I understand the 6.7 liter of course get’s poor mileage and is breaking down on them. I wonder if Nissan did this.
    Best of luck, Toyota next time.
  • Was wondering how many years and miles you may have gone on the timeing belt? and if it broke at what miles?

    I think the Off Road model with automatic tranny has a poor rear end ratio for fuel economy at 3.357. It's built for power.

    My wife is considering an X-terra and I'm thinkin' that the S with the 6-Speed stick might hopefully do okay in the MPG Dept. I normally average 22.5 to 23 MPG with my '06 Frontier SE 4x2 Crew 4.0L 6-Speed driving conservatively at highway speeds, but I don't know how this would translate to an X-Terra.
  • Thanks for the reply,
    I didn't know that the 3.327 rear axle ratio was different for 6 spd. Transmission. Thanks for letting me know. I still think it might be something else. The 2008 Xterra is getting 15-16 MPG on the highway and slips to 10 off road. The Xterra does have a lot more power than my 1999 Jeep Cherokee 4.0 liter auto with a rear axle ratio has 3.55 ratio. The Jeep definitely does have a higher ratio because the Jeeps engine RPMs are higher for the same speed. But the Jeep gets 22 MPG on the highway. I am thinking the Xterra has a large overhead rack (wind drag) on top. I am considering taking it off as a test?
    The other thing might be my Jeep has a conventional automatic transmission. When did the Xterra go to the CVT (continuously variable transmission)? This is the very first CVT I have had on a truck. I have had them work well in snowmobiles and go-carts but a truck… maybe that’s it???

  • We are up to 15.5mpg in the city...we almost 2K on the odometer. We will be taking it on a 900 mile round trip this week so I will post those numbers when we get back.
