    I just purchased a 2000 club cab 4.7 with factory 31inch tires. The truck only has 30K on it. The gas mileage is horrible, i've tried airfilter, gas treatment ect... The plugs appear to be fine. The truck has a 22 gallon tank and gets 210 miles per tank. ANY suggestions would be helpful

    You did not say if it has 4X4 and you did not tell us the differential ratio. If you have the optional ratio designed for towing, your MPG could be impacted.

    I can tell you that my 2000 Dak with 4.7L SemiHemi and manual xmission gets about 200 miles at the HALF tank mark and can touch 300 miles per tank if I want to push it. (shape of gastank makes second half of tank go faster)

    I can tell you that 30,000 miles is still below the point where my engine "loosened up". Perhaps as you continue to drive the MPG will increase. (dont forget the all-important bursts of full-throttle accelleration to help seal the rings.)
  • I had a 2001 4,7 4x4 and now I have a 2006 4.7 4x4. The 2001 had all wheel drive as standard with 4 wheel as optional, the new truck is rear wheel standard. The 01 would get about 14, the 06 gets about 15. I drive a mix of about 50% highway and 50% backroads. MPG is not the greatest. I have heard that conservative driving adds couple of mpg's but I cannot seen to drive that way. So many recommendations, air filters, plugs, oils..... My suggestion. Get used to it or get rid of it.

    actually, xscout they proved on mythbusters that driving with the tailgate up gives better mileage ;)
  • xscoutxscout Posts: 141
    Interesting! That seems illogical, and I've always heard the opposite, but sometimes you get a surprise!
  • bpeeblesbpeebles Posts: 4,085
    There is a website you can search for in which a college student did his thesis about this subject. He collects a lot of data and the results are interensting.

    In short- Adding a cap or a tonno cover gives better MPG due to the smoother airflow over the rear of the truck.

    The reason the airflow is better with the tailgate closed/up is because the air that hits the tailgate comes back forward and forms a bubble, and subsequent airflow goes over this bubble and over the tailgate.

  • 01 Dak Quad Cab 4X4 2657016 GY RTS, tow package, ARE MX Shell. Bone Stock engine, Castol Syntec and all synth fluids. 65K miles total.
    14 around town, only 6 miles to work so it rarely gets fully warm. 19-21 highway at 70. Worst milage 6, in deep sand at the beach. Guess what if you drive enough on the beach with RTS raised outline white letters, you get partial whitewalls, or at least graywalls.

    I'm having the dreaded sway bar squall. Any ideas on what to lube them with? Since I beach drive a lot, I want a dry lube if possible. Does Dodge make a retrifit kit to the later sqeak resistant bushings?

    BTW, I spend about an hour with a leaf blower and a hose sprayer getting sand and salt out of the frame and undercarriage.

    Hi all. I'm currently weighing whether or not to purchase a used '07 Dakota 4x4 with the HO V8. The dealer is telling me it takes regular, but from what I'm reading premium is recommended. Anyone have experience with this? Also, any significant difference mileage-wise in running regular vs. premium in that engine?

    Any insite would be much appreciated.

    Thanks!
  • dustykdustyk Posts: 2,926
    In 2003 Dodge changed the sway bar bushings to a different material. Mine have never made a noise. I would suggest checking with a dealer for replacements. I have seen aftermarkets available, too, but I cannot attest to their improvement over the newer facter bushings.

    Best regards,
    Dusty

    Change the oxygen sensors.
  • mtrialsmmtrialsm Posts: 159
    Is anyone driving a new V6 Quad? What is your gas mileage?

    If the oxygen sensors were outside tolerances, wouldn't it generate a fault code for the computer?

    :lemon: I have 2800 miles and get about 9-10 MPG...what's up with that??
  • dustykdustyk Posts: 2,926
    From November 1st 2007 through 31 March 2008 the average fuel mileage on my Dak is 16.45 MPG. The lowest tank was 13.91 in mid-January.

    So far with the warmer weather in April the average is 17.73 with the last two tanks over 18. The total to-date average for 66 months is 16.89 lifetime. I now have 98136 miles on the vehicle.

    now has 200,000+ miles, always used lowest grade fuel (87 in w.tx./n.m. but 85 in colo.), but here in w. tx. our fuel is 'freshly minted' without a few additives seen elsewhere... shell fuel is one of the best about low additives, as porsche recommends it for my 944 and all their 911's and boxsters too. their fuel makes for a denser charge and better flame-front (with good plugs and ignition). i have no reason to doubt them, though i don't really like shell much. nobody out here in the w.tx. oilpatch likes them or oxy.
    lowest mileage was before it broke in fully at about 8k. overall was about 12-13 in town, 18 hwy. after break-in i have regularly gotten 15+ in town and 19-20 hwy. lowest when pulling 5k# trailer in oilfield (don't have figures, but LOW) and highest in mountains of colo. with large suzuki 1200 madura or yamaha xs11 midnight special in bed - 550# or so - averaged 'well over' 20 mpg (i calculated couple of tanks at 22+ mpg back in '01 in colo. mtns. on 85 octane gas!!!). mileage went down when i changed the orig. plugs with splitfires (significantly) at about 110k. i put the old ones back in, mpg went back up. replaced them at just under 150k with oem from dodge dealer. mpg is still good, but i don't drive it much now. will check back here with fresh results. i've kept every receipt and mileage book since day one, and i might go look all that data up someday... would be a large data post...
    btw - this dakota has NEVER been in the shop for anything. i've fixed all the little user-issue stuff myself, changed the fluids (except for tranny flushes) and i'm no mechanic. it's been a superb truck. still looks brand spankin' new. i've had many, many cars/trucks and it is the BEST by a long shot. it'll see 1/2 million miles fer shur before i park it in the collection. proudly!
    my overall feeling is that a 4.7 dak, setup like mine, gets the worst mpg when it sees a tundra next to it at a stoplight (or one of the cartoon diesel trucks with the HUGE exhaust and the lil gauge pod thingie in the a-pillar), and it gets the BEST mpg when driven just under 2000 rpm - steadily. it's a torque 'sweet spot' that's hard to maintain since the engine is so playful right about there.
    addictive is another word.

  • my 2000 Quad Cab has the 3.9 V-6. I have an AirAid Short Ram intake and Gibson Headers with a Gibson Catback exhaust. on a trip from Oceanside to San Fransisco I got 23.7 almost all highway. lately Ive been doing more city driving and getting 17 though.
  • how is your driving style?
  • dustykdustyk Posts: 2,926
    At 100779 miles my Dak now has a lifetime average of 16.93 MPG.

    Interestingly, in April when temperatures here were still in the thirties and forties, I ran five tanks of Mobil 93 high test through the Dakota in a row. I noticed that the idle seemed to improve and gas mileage jumped from a previous four week average of 16.43 MPG to 17.21. When switching back to Mobil 87 it remained the same.

    Except for changing out the rear differential fluid, I just completed a full tune-up:plugs, PCV valve, air filter, and oil change. I had 49,814 miles on the Bosch Platinum Plus 4s and the air filter didn't seem very dirty.

    I immediately noticed a difference. The engine was definately performing better with stronger launches and noticeableby more effortless at cruising speeds. Since this the average has jumped to 18.43 with one tank at 19.88. These were mostly around town miles with about 30% expressway driving.

    Although I've recommended the Bosch Platinums to others, this is the second time I've noticed a difference after changing them out. The first time I cannot say I saw a big increase in gas mileage, but then again as others have noticed, the more miles you put on a 4.7 the better they run and the better the gas mileage gets. Anyway, despite claims I wouldn't leave these plugs in for 100,000 miles.

    i have 2002 3.9L club cab and i get about 12 mpg. i dont hot rod it. i just drive around town, all city driving and usually just for short trips to work or store. it hasnt been on any long huals. but just around town i get 12 mpgs. 230 miles out of a tank, is this normal or what can i do to impove it. i already purchased a k&n air filter.
  • bda54bda54 Posts: 8
    You didn't mention if you have a 2WD or 4WD. A 3.9 should do better than your getting. A mechanic friend told me to pull and clean off or replace my O2 sensors on my 2003 4.7 Quad Cab. Another concern about the K&N air filters that was mentioned on this site is that the oil can possibly contaminate your Mass Airflow Sensor if it is put on too heavily and the residue coats the MAS. One other idea that I have gleaned from this webpage is that switching to all synthetic lubricants in the engine and entire drive train. Redline Lubricants sound interesting, though expensive. Amzoil would be another alternative. That is the way I'm going to go with my Dakota. Good Luck!
  • dustykdustyk Posts: 2,926
    If you are doing all city-type driving, you are in the worst scenario for gas mileage. Short trips are especially bad since the engine remains in the rich mode most of the time. The constant accelerating-decellerating also is especially bad for fuel consumption.

    However, you didn't tell us how many miles you had on this truck. Its possible it could benefit from a tune-up if you haven't performed one yet.

    I have a 2K Dak with a 4.7 engine, and I didn't think that we had mass airflow sensors. I looked this up in my factory service manual and couldn't find a MAS. I know my Ford products respond extremely well to the cleaning of the MAS. Is there a Dak equivalent to the MAS in Ford products.
  • bpeeblesbpeebles Posts: 4,085
    You are correct.... the 4.7L semi-hemi does NOT have a MAF (MassAirFlow) sensor.

    Instead, it uses MAP (ManifoldAbsolutePressure) sensor.

    MAF actually measures airflow. (much more accurate, costs more, ignores dirty airfilter, more susceptible to contamination and burning out.)

    MAP has to CALCULATE the airflow based on pressure differential. (less accurate and sensitive to dirty airfilter, very reliable)
  • bda54bda54 Posts: 8
    Can anyone recommend or compare Redline lubricants to Amzoil for the entire driveline of my '03 Dakota Quadcab, 4.7, AT, 4x4. I live in Minnesota and drive it primarily for work, but use it for hunting, but no heavy off road use. Also which oil filter would be best for use with the synthetics? I've heard Redline lubricants are spendy, but how spendy compared to Amzoil?
  • jboehmjboehm Posts: 44
    Anybody have some real world numbers on a HO engine and a FFV engine?
  • bpeeblesbpeebles Posts: 4,085
    I just checked my receipts when I purchased the RedLine lube for my driveline. (both differentials, xfer-case and manual xmission) I paid $8/quart.

    The RedLine PowerSteering fluid was $9.50/quart.

    When considering this, one must consider the VALUE and not the initial cost. For me, my rear differental was saved from self-destructing when all the fluid came out. (but RedLine leaves lubricating residue.)

    Also, my powerSteering no longer needs 5-minnutes of warmup in the winter before it starts to work. (-15F)
  • bda54bda54 Posts: 8
    Thanks for the reply. Do you know of any independent testing comparing Redline lubricants to Amzoil or other synthetics that can be checked out? I had forgotten to think about the power steering fluid.
  • bpeeblesbpeebles Posts: 4,085
    I am not aware of an "independant" testing. Amzoil is somtimes marketed thru individuals who often make claims that even Amzoil does not acknowledge.

    Keep in mind that RedLine uses 100% pure synthetic polyol ester basestock. This is expensive stuff that most off-the-shelf oils do not even consider using. Competetive Racecar teams use RedLine becauese it works. (reguarless of what the stickers may say on the OUTSIDE of the car!)

    Here is webpage for RedLine ==> http://www.redlineoil.com/default.asp

    The polyol ester basestock is used in extreme-duty conditions (Jet turbines, aerospace...etc) and may be more than the average driver needs in his road vehicle.

    I beleive that Amzoil may also use some polyol ester basestocks... but over the years I have become put-off by their marketing (pushiness).

    The Federal law was changed in recient years to allow manufacturers to CLAIM an oil is "synthetic" even though they contain petroleum-based oil. (MOBIL1, SYNTEC...etc fall into this category) These are not The polyol ester basestock!

    My young son and went to the Mopar Car Show in Carlise two weeks ago. Leaving Rochester, New York on I-86-US17 to US15 south, my '03 Dakota (Club Cab Sport, 4.7, 545RFE, 3.55 LSD, no mods) got 23.92 MPG on Mobil gas. That included 41 miles of town driving.

    With the exception of about 1.5 minutes of actual passing, I kept the cruise control set at 62 MPH all the way to Harrisburg on US15. On 55 MPH highways I stayed at the speed limit.

    The return trip, however, was 22.71 MPG on Amoco with 10% ethanol.
