Ford Explorer Mercury Mountaineer Real World MPG



  • I got 16.75 MPG on mixed highway(stop&go)/city in SoCal on my first full tank. The computer MPG wasn't too far off as it reported 17.2 MPG.
  • I'm considering buying a 2002 Ford Expl Limited. I have a choice between the V-6 Flex Fuel and the V-8.

    I'm concerned about all the comments I've heard that Explorers don't get the mileage their EPA estimates call for.

    What kind of MPG are folks ACTUALLY getting on these two engines, in town an highway, please?

    '02 explorer, about 64k miles, v8 w/tow package. 16.2 lifetime average.
    newly licensed driver averages about 13mpg in local only driving.
    from central ct to washington dc area via pa, four on board. 16.8 on the way there; cold, windy, rainy, no traffic. 380+ miles in 6 hours. ;) some local driving plus the trip back, warmer, some traffic, 18.6 average.
    epa is 14-19.

    2002 V6 Mountaineer 16 city, 20 hwy.
    2004 V8 Mountaineer 13.6 city, 18 hwy.
    2006 V8-3V Explorer 13.6 city, 19 hwy

    As you can see, I prefer the V-8. The new 3 valve V-8 give you a ton more power, but the 6 speed tranny, gives you the same mileage with more power.
  • 2004 Explorer XLT 4WD 4.0L V6.
    HI-22.02, LO-11.72, AVG-17.34.
    Gotten 22 MPG on a trip, and 12 MPG 4WDing.
    Overall this gas mileage sucks.
  • With 29344 miles, my 6 speed has recorded an average mileage of: 15.88 mpg. I am happy. This is about 1 MPG better than I expected for a gas guzzling V-8. BRAVO for the 6 speed tranny. Best mileage on highway (@ constant 68-70 mpg)>20.7, worst mileage> 12.8 (cold weather). Only complaints: dinging OTHER peoples' doors due to the moron who desinged the idiotic lack of control of how to GRASP the Explorer door as it SWINGS OPEN (bam !!! Ding !! Whap !!) Whoever designed the Explorer door should be taken out and run over by a...TOYOTA 4-Runner (a vastly better eingineered vehicle).

    TOYOTA 4-Runner (a vastly better eingineered vehicle).

    Vastly? My, we are given to hyperbole, aren't we? I disagree, but it may be more symantical than actual. The Explorer is a superior design in every way. It rides better, the third seat is actually adult friendly, and folds away. You can see over the hood without the power dome getting in your way, and see the road, the independent rear suspension makes the stepping over bumps or rocks much easier on the spleen, and the new 3V 4.6L motor with the new 6 speed transmission is just a honey to drive.

    Now, the Toyota will run twice as long, with half the problems, I'll give ya that, and if by that you mean engineered better, then fine. But the Ford "design", is vastly superior to the 4-runner.

    Of course, I could be wrong.....
  • I think I've discovered the difference between my good '02 Explorer mileage and what I'm getting with the '06. The '02 had the category II (small receiver hitch) towing package which had a 3.55 gear ratio, and the '06 has the cat III/IV package which mandates a 3.73 ratio. Sure has more dig, though.

    Bingo!!! That is exactly the key, mate. :P

    I have a 2006 Mercury Mountaineer with 1895 miles on it. I average 13.5 MPG in the city and 21 MPG on the highway. Love the car. Was not overly worried about the MPG, but with the rise in gas prices, WOW!!!

    31-10.5/15 tires a/c compressor runs no matter what you do so winter/summer dose not seem to make much difference i get 13.8 mpg average i have a 3500lbs camper and that dose not make a difference

    at over 2200 meters above sea level I get around 17 mpg in city driving, havent taken it on the highway yet.

    I have a 95 Ford Explorer V6 motor with about 115,000 miles on it ... as of late I am loosing about 2 mpg off of my average from 6 months ago. I recently replaced some vacuum lines that were cracked and I just put in a new fuel pump. The car seems to run fine just lower gas mileage.... Any clues???

    I have a 2001 Ford Explorer Sport.

    It still has the original Michelin 235/75R15 tires on it but after 6 years its time to change them.

    That bring in 2 questions:

    1)Is it possible to install thinner tires.. maybe like 215 or 205 if i respect the original height?
    -Would this make the vehicle any less safe?
    -Would they fit the original rims?
    -Would gas mileage really be reduced a little bit?

    None of the tires are too worn (Explorer was only driven 40K miles on them) yet the tires are 6 years old but only the front ones have little cracks on the side which make me uncomfortable to take the Explorer on the highway (usually drive only in city traffic).

    2)The spare tire is brand new cause its never been used ... yet its been down under the Explorer for 6 years. If I only want to change the front tires for the moment could i use the spare and only buy a second tire or is it too dangerous and i should change all tires?

    Thanks for the help!!!!

    I'm curious. What makes you think your mileage will change?

    If i change tire size from 15" to 16" will i get better milage?
  • Im wondering if thinner tires would cause less friction/drag therefore increasing mileage...
  • tidestertidester Posts: 10,110
    If there is no adhesion between the tires and the pavement, then the coefficient of friction (rolling) should not vary with contact area. And if it does, the change will be negligible in terms of mileage improvement.

  • There would be a slight reduction of friction between the tires and road surface. Slight being the key word, so slight that you would never notice it in a fuel mileage calculation. However the reduced surface area of your tires may Greatly impact your traction. Reduced traction will go unnoticed until you really need it. Situations like emergency braking, an evasive move in traffic, poor weather, will all bring it to your attention. Sure the ABS will still activate correctly but it will have just that much less area to work with. IMHO it's not worth the trade. As for the tires fitting the rim, any good tire shop would be able to tell you, I really don't know. As for the spare, it's the same age as the original tires, I'd leave it as is, as a spare. Good luck to you and I hope you can find a good deal on some tires.
  • I just recently purchased an 02 Explorer XLT - V8 - 4.6L
    I have an 11 mile commute to work, little to no traffic. In the last few days, my 11 mile drive uses a quarter tank of gas! I have checked the standard stuff, ie; fuel filter, pump, fuel injectors, air filter etc. and there is no leak. What could be causing the absolute crappy gas milege??
    Any advice is greatly appreciated. :confuse:
