    I am getting the same gas mileage in mine. It is frustrating and expensive. I have a 2005 touring edition. I have gotten as low as 12.5 in the city, but fare about 18 on the hwy. I end up averaging about 15 overall.

    We just bought the 2007 AWD Touring and are getting an avg. of 20.5 mpg...it's almost all highway miles. I also heard that this should improve as the car "gets used to" my driving, but I'm not holding my breath on this one!

    darn. we're now at around 20k miles in our '05 and have never gotten that high, even on the highway. And you have the new bigger engine. congrats! :)

    Had one of my lowest average MPG's during the past several days while running the A/C and hauling more people. My "low" was 17.6 which included in town and daily round trip to work. My average prior to that was 19.4-20.5 combined in town and short highway trips to work and back--which are done at a good clip. My last highway trip--with just me and my luggage but at...um...."good" speeds was 24.5. I'm taking a similar long highway trip this weekend so I'll let you know.

    that reminds me. We took ours on a trip to Long Island a couple of weeks ago and got our best mileage ever. 20.3 mpg average from start to stop. Terrain really does make a huge difference. We could never achieve that in Jersey due to constant elevation changes in the highways. The relatively flat cruising on LI drove our mileage way up.

    I had a 2004 FWD from vehicle mileage 12k to 24k and got a little over 20mpg average for the 12k miles driven in 5 months. Mixed city/highway.

    First way, traveling at 75-85mph, just under 600 miles, average mpg was 24.1. On the return trip, slightly slower speeds, 25.6mpg.

    OUCH!!
  • Hi,
    I leased a 2006 Pacifica in November 2006. According to the trip thing on the dash, I am currently getting 13.8 average daily millage. I has read 13.8 since the 1st day that I drove it out of the lot. It never changes. But, I am not satisfied. Thank GOD that they would only give me a 2 yr lease.
    Does anyone know if maybe the dash reader is stuck and how can I reset it?
    THANKS

    With the EVIC set on reading the Average Fuel Economy, press the Reset button below the Step button. I have found that I sometimes have to do this several times or hold the botton down a while before it resets. You'll know that it's been reset when it starts reading 30 mpg+ when you are coasting. I think you need to do it while it's in park, but I'm not sure.
  • qbrozenqbrozen Posts: 17,477
    you can reset it at any time.

    maverick, how many miles did it have when you got it?

    and, really, number of miles don't even matter. It could have sat still at the dealership at some point idling for hours (effectively registering 0 mpg). That will prevent you from getting the mileage number to raise for a LONG time.

    But, forget the reading, what mileage do you ACTUALLY get? You have calculated it ... haven't you?

  • it's about 14.

    NOT GOOD
  • qbrozenqbrozen Posts: 17,477
    AWD or FWD?

    personally, if i was confident it wasn't my driving or WHERE i drive that caused such poor mileage, I'd at least try resetting the ECU (disconnect the battery for a half hour). Then start all over again. If mileage is still bad, well, I would complain to the service department, but I'm sure they'd say its all find and dandy.

    I have a 2007 AWD. I get as high as 25 - 27 on the highway and typically average 19 - 20 mph.

    You NEED to use the cruise control and you will get much better fuel economy. The car's ECU does a much better job managing load then you can with your foot.

    The Pacific is really no different then any other car. They suck in stop and go traffic and around town. I do get as low as 12 mpg around town.

    My 2003 Saab 9-3 runs 32 - 34 on the highway and 15 mpg around town with a typical average of 26 mpg.

    My 500 hp Mustang runs 21 mpg on the highway and about 12 mpg around town.....much less when having fun - lol

    As far as the fuel computer, simply press the reset button twice and it will reset right away. These devices are pretty acurate, but expect them to read about 5% high. They do NOT actually measure fuel comsumption, but rather use the fuel tables which are built into the ECU to perform an estimate.

    All fuel injector cars have fuel injectors. They are rated to deliver a certain amount of fuel per pulse. As the car adds load, the frequency and length of the pulses increases. The car's ECU makes this determination based on throttle position (TPS), air flow (MAF sensor), and finally the O2 sensor.

    The O2 sensors determine if the car is running rich or lean, and adds fuel accordingly. The mpg computer assumes that the correct air fuel ratio is being maintained by the O2 sensors. But, the O2 sensors use narrow-band technology and are not as accurate as they could be. As such, the car "thinks" it is running say 13.2:1 ratio, when in fact, it might be running 12.5:1 and as such, you loose fuel economy directly proportional to the difference in the desired O2 level.

    The way to fix this is to have the car tuned on a dyno by a qualified tuner assuming that the O2 sensors are working properly. The tuner will install a wide-band O2 sensor and run the car under hard load. The tuner can also adjust the air fuel ratio and adjust timing to get the proper tune that you want. You can either add hp, or increase fuel economy, but generally not both. The cost is about $500 - $700....it is not cheap. Or, you can simply have the air fuel ration checked for about $70.

    If you have seen your mpg drop over time and your car has miles on it, the culprit is probably the O2 sensors. I have not replaced one on a Pac, but it is litterally a 20 minute job on my Mustang and the sensors are a few hundred $ usually. Always buy them from the OEM....the after-market ones usually don't work very well.

    Hope this helps.

    BTW, keep your tire pressure up. I run mine at 40 lbs. Higher pressure will result in better mpg, but a stiffer ride. The manufacture recomends lower pressure for the ride quality.
  • qbrozenqbrozen Posts: 17,477
    Higher pressure will result in better mpg

    As well as uneven and premature tread wear.

  • waterdrwaterdr Posts: 307
    Not true. The tires are rated for much higher pressure then what the car manufacturer recomends because their focus in on ride quality.
  • qbrozenqbrozen Posts: 17,477
    Well, I never go by the car manufacturer. I go by the pressure on the sidewall. Maybe your Pac's tires are different, but I'm pretty sure most tires still say 35 psi is ideal. Yes, their MAX pressure is higher, but that doesn't mean it won't adversely affect the tire to drive with them like that.

    Edit: This is from tirerack's site:
    A tire's "maximum inflation pressure" may be different that the assigned tire pressure used to rate the tire's "maximum load". For example, while a P-metric sized standard load tire's maximum load is rated at 35 psi, many P-metric sized standard load performance and touring tires are designed to contain up to 44 psi (and are branded on their sidewalls accordingly). This additional range of inflation pressure (in this case, between 36 and 44 psi) has been provided to accommodate any unique handling, high speed and/or rolling resistance requirements determined by the tire and vehicle manufacturers. These unique tire pressures will be identified on the vehicle placard in the vehicle's owner's manual.

    So, what they are saying is, due to changes when the air heats up, rolling resistance, etc, a tire that is inflated to 35 psi COLD can handle more. But inflating to 40 psi COLD would then surpass the tire's manufactured limits when heated up and travelling at 70 mph with a full load.

  • Like many others here, we are disappointed with the mileage we're getting from our 2004 AWD Pacifica. Around town we get 13 - 14 and on the highway it's about 17. Thinking about trading it in for the Highlander Hybrid . . . :mad:
  • waterdrwaterdr Posts: 307
    That is really poor. I have averaged 19 - 19.5 on the last two tanks and see 23 - 25 on the highway. Fuel economy should ntot be that different.....yikes.

    BTW, you will be equally ticked about the Highlander Hybrid. While you will do better, plenty of people aggrevated about them as well when it comes to not matching the claimed MPG.
  • waterdrwaterdr Posts: 307
    I see the Highlander Hybrid is rated in the mid 20's, but folks claiming 20 - 21 mpg average....2 mpg better then what I am getting. All from a car that has a $35k - $40k MSRP and they get a premium for the Hybrids to boot.

    I am just not convinced about Hybrids in general. Technology is just not there yet.....not worth the price to me.
  • faroutfarout Posts: 1,609
    8000 miles and 20 to 22 in local hilly area, to 24.3 on 140 mile jaunt. I think 25 is a real mpg on a longer trip.

    farout
  • First off the dash readout isn't 100%, the only real way to get your MPG is to take your trip mileage and divide it by the amount of gas used.
    2005 Touring, AWD highway I get 18.5. there is a small portion of stop and go (bumper to bumper).
    Its a decent car, good in snow, bad on gas. Front end is getting clunky, lets hope its not a ball joint.
    Also is due for a tune up, and a timing belt. (80K miles). Just put on new tires by cooper, WOW much better than the junk stock tires.
  • faroutfarout Posts: 1,609
    You might not know that the 07 has a 4.l engine and a 6 speed automatic, which makes better fuel mileage. I do not go by the computer, I use actual gallons used into the miles at the last fill up until now, However the computer is not very far off, compared to other Jeep Vehicles I have owned.

    farout
  • waterdrwaterdr Posts: 307
    I have found the computer to be nearly spot on, but I have not had the car long. My Saab's computer reads consistently 5% high.

    Most of these devices work by "calculating" the fuel consumption rather then measuring it. I don't know how the Pac works. On most cars the computer calculates fuel consumption by looking at fuuel injector pulse widths. Assuming the car has an accurate O2 sensor (which narror-band units are not the best), you can get a pretty close approximation.

    The 6 speed helps a bunch on the newer ones I would imagine.

    I just traded my 05 touring in on an 07 base AWD with the 4.0 L engine. I had 89500 on my 05, ,perfect car, no trouble with that car (it was slow though) and it stayed at 19 - 20 mpg on the highway (measured by noting the amount of gas to fill up after trips). I got a good deal on this newer car so I am also hoping that the improvements on the 07 are as good as they say as far as mileage (24 highway). One thing I would like to ask is in my 05 touring the EVIC, gave me a some estimates on fuel economy and distance to empty. This new car's EVIC does not provide the same info, it just tells me is there is an issue or it tells me the service interval - is there anyway to, simple to upgrade or fix this issue?
  • waterdrwaterdr Posts: 307
    I have a 2007 Limited AWD. The EVIC on my car provides the same info that you claimed your 05 did. I wonder if you have an issue or if it is just setup incorrectly.

    Glad to see a PAC owner returning again for a new one.

    How do you like the new motor and the 6 speed? Do you have a FWD or an AWD?
  • waterdrwaterdr Posts: 307
    Sorry to respond so slow....you are correct, but the pressure does not change by that much. I see an increase of about 2 to 3 lbs from cold to sustained highway speeds, but I also suppose it depends on ambient temps as well. I fully intend to pull a few lbs out in the summer.

    On my Mustang I routinely run my pressure in the rear tires at about 26 psi as I need all I can to get traction. When drag racing, I drop it to 18 lbs and pump the fronts up to about 42.

    The lower the pressure, the larger the footprint.

    Lower pressure equals softter ride and better traction. Higher pressure equals firmer ride and better fuel economy. You just need to choose your battle and decide what you want.
  • nuruc7nuruc7 Posts: 98
    Oh the new motor and transmission combination is quite strong. It does get there faster, a lot faster than the 05 touring I traded, and once it is there then is rides comfortably at 2k rpms at the same speeds or greater that the 05 would be running at 3k or better. So it looks like I will be saving a bunch on gas. I am pretty sure that car is not set-up correctly for EVIC. However it is telling me that 3 tires are under inflated and I am gonna review the manual to see if certain faults lock the reporting up until it is cleared/or the problem is corrected. Also I see in the manual that the cars come with the base speedo cluster and the Premium speedo cluster, and mine is a base model with AWD and the 4.0L, and it has the Premium speedo cluster and EVIC controls, so the EVIC is there but appears to be not working correctly. Hopefully there is no difference between the base, touring and Limited as far as the standard EVIC is concerned if it is installed. I know different options would not be present.

    I will let you all know what is happening later after the dealer gets back to me. Yes I could not pass up the deal they were giving me to get me oput of my upside down 05 car with 89k on it. However the car did run great, no issues, and was a touring with full leather and most of the amenities. I will probably do this one like I did the last one and put in some add-ons. I added satellite and the DVD player and drop down scrren. This one comes with Sirius satellite so I am set there. Still debating on upgrading the seat upholstery to the comfortable leather. Don't have sunroof, but could get that installed - probably won't as, i really did not use it at all. I kinda opened the moon roof shade, but ended up not even using that. This has more headroom so I am fine. :D
