Paul: I have tried 89 twice in 15,300 miles, and it made no difference at all. Perhaps pulling a trailer at high altitude the 89 might give a little more pep. We have the AWD Touring, and get 22.4 in hilly stop and go traffic, and have an avrage 24 mpg combined mpg. Unless you get the Touring or Limited with FWD then you are NOT getting the 4.L 6 speed automatic. Unless its new you won't get the Lifetime warranty, so check it real good.
 
I would think the 08 would be a good bet.

Thanks for the insight.....
 
My plans are to locate a new Limited '08. I do not want a used one.
 
Are you sure about the 4L/6 speed combo in the Limited if its AWD? The way I read the Chrysler bragsheet, thats the only transmission that comes with the 4L. Still haven't decided whether I need the AWD..... my '04 doesn't have it and I seemed to do pretty well without it.
 
On the other hand, the person I carpool to work with has a Ford 500 with the AWD, and he loves it and says he can feel it kick in on wet pavement! I can't tell.
 
Can you tell when you change from FWD to AWD? Is it noticable? How can you tell it is actually doing anything?
 
Thanks....

The only PAC that comes with the other engine and 4 speed automatic is the Base PAC. Allthe others have the 4.L engine. Sorry if I was not clear on that.
   As for the AWD, my mpg is the sme as those that have the FWD. I don't think there is any change in AWD as it is always in all wheel drive. We live on a steep hill that has lots of gravel (large rocks) and dirt and mud and and ice sometimes in the winter. We had Jeep Liberty's before, and the PAC AWD does the job just as well except we are not getting beat up so bad! If the AWD was not working we would never make it up in the snow and ice.
   You may have heard but Chrysler LLC was down 23% in sales last month, that hurt them bad. Most likely because that the PAC has about stopped being made (somethim this month) and there is a 77 day supply of vehicles and perhaps more than that with the PAC AWD you can get a super good deal now.
    Last August we got $7,000. total off and 6.9% for 72 months. So we feel we got a good deal. That with the Lifetime Powertrain Warranty and we got the Max Care Chrysler Wrap Warranty and this just might be the last car we need to buy. (we are retired) Already owning a PAC and if you are getting 23 mpg you will surely do better with one of the new 08. The power of the 4.L is great and it goes quick and smooth. Hope this helps, let me know how it turns out.

I have had 2 2007 AWDs with the 4.0, the base model and the touring model, both have the 6 speed engine with the 4.0L engine - very good gas mileage compared to the 2005 touring I had. The 2007 touring gets 24 or so on the Freeway, 20 or so on the streets (not a lot of stop and go )

I own a 2006 Pacifica Touring with 51,000 mi. First I changed the oil to Royal Purple synthetic oil. Then, I added a K&N oil and lifetime air filter. And finally I added a cyclone fuelsaver. The following is a list of MPG DIFFERENT speeds:
45mph 33 mpg
55mph 30.5 mpg
62 mph 29.1 mpg
70 mph 27.0 mpg

Hey, everything is looking for the "fountain of youth" when it comes to getting better MPG. Synthetic oils have very little impact. There have been tons of independant studies done and none have shown this. Also, additives don't work either. IF, a motor has that much friction such that changing oil would save fuel, there would be enough heat produced that the motor would melt. K&N filters will provide a legitmate improvement of a few %. You might actually see a 1 mpg improvement from one. I use them.
 
Cyclone fuel savers are completely, 100% bogus. First, someone has to prove that simply taking air and swirling it does anything, THEN you need to explain how the swirling effect is then able to bend around corners and angles in the upper intake. Let us not forget too that the air enters the combustion chambers by way of valves which open and close. If you have ever seen what an upper intake looks like, you would not have installed one.
 
In fact, these devices can actually make complete havick of your MAF. The MAF is designed to measure airflow in the intake. It is imperative that the flow be laminar in order for them to function properly and the sample tube is designed as such.
 
As to your data, unless you were driving on a flat surface for many miles at these speeds and verified with fill-ups, the data is not very accurate. The MPG reading uses data provided by the ECU off of the fuel tables. In the event that the MAF is now reading correctly, it is entirely possible that the car is now running incredibly lean.

Any ideas on how to imporve my gas mileage by judykathleen

My 2004 Pacifica is in the toilet regarding gas mileage. It gave me a readout of 14.5 average. Is this an eye opener for any other owners? I'm thinking tune up, fuel filter, air filter or something cold help, or is this just the nature of the beast (bad mpg)?

Have you checked the accuracy versus your fillups?
 
I switched to synthetic oil and a K&N filter and that helps a bit. It will vary how much depending on the engine and your driving style.

You don't say how many miles are on your 04 PAC. Does it have the 3.5 L or the 3.8 L engine, is it FWD or AWD ? these are just the start of the information needed to help you. Also there are lost of minor things you can do like , oil & filters changes, tires ballanced, replace spark plugs, clean the injectors, change transmission fluid & filter. There are lots of things you can do, but if the car has been treated by schedule B or A in the owners Manual you would have a pretty good idea what has to be done. If a Chrysler dealer did the service work on it or if there was a TSB or a Recall this too would show, and you can call any Chrysler, Dodge, Jeep dealer and ask the Service dept. to look it up for you, it;s a free thing they do. If you give us the VIN # we can find some of this out for you.
    However the best way to get good mpg is the way you drive. Be smooth, and even what some might call slow starts and stops. This can recall help more than all the things above all together.

It has <47,000 miles on it. I have bought new tires (so balanced). I had the transmission fluid changed at 33,000 miles. I do my oil changes. It had new brakes put on it. I don't think I am a fast stop/start driver. I am between looking for something else (but like the Pacifica other than gas mileage), and investing in plugs, filters etc. I will probably keep it, but don't have a clue about mechanical stuff and what to do to see if it can get better mileage. VIN 2CBGM68424R629976. I would appreciate any input to help me with gas mileage.
