Chrysler Pacifica Gas Mileage

Hi - I and likely others are interested in hearing - what is your current Pacifica gas mileage? Ours is 14 City, 16 Hwy, 15 Combined - far below what was promised. Please let everyone know Year, City MPG, Hwy MPG, Combined MPG. Thanks!

    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: 16,897
    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: 16,897
    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: 16,897
    Higher pressure will result in better mpg

    As well as uneven and premature tread wear.

    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: 16,897
    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:
