2005 Club Cab 4x4 MPG by ata3001

I have a '05 Dak 4x4 CC 4.7 w/ 5 spd auto 3.55 as well. My last tank got me just under 19 mpg combined 20% city/80% hwy. This is an actual calculated figure. The computer showed 19.3 mpg (slightly high). On the road I can get about 23 mpg. Not complaining. Towing 3500 lbs is about 12 mpg.

I calculated the mileage myself, after I didn't believe what the trip computer showed.
 
I've always gotten better mileage than EPA estimates, regardless of what vehicle I'm driving, so I guess I can chalk it up to driving habits.

Fuel Mileage: 2003 4.7 Auto & 3.55 LSD by dustyk

Since I installed new tires in January the fuel mileage dropped. After realizing that the one size larger tire offset the oddometer, and with the comensurate correction, there appears to be a .2 drop in the average. The new tires are about an inch wider that the factory tires. They're supposedly the same wear index, but these new Michelins seem a lot softer compound that the Goodyears.
 
Still, the average over the last 20 tanks is 17.56 MPG. This is mixed driving, 70% around town, 20% open country roads, 10% expressway. A recent trip with a 650 lb. ATV and 400 lbs. of gear yielded 22.31 highway (60 MPH).
 
Regards,
Dusty

Dusty,
 
At least you've only dropped about 0.2 MPG. When I put on new tires, I dropped about 1.0 MPG. Out of curiosity, I looked at some of the tire ratings in Consumer Distorts. Most Truck/SUV type tires tended to have poor ratings for rolling resistance. The tires I purchased, were rated "poor" for rolling resistance. Oh well. Maybe I should have looked there before buying.

Sunburn,
 
Well, that's a .2 drop in average over the fillups since I put the tires on it, compared to the same time period the year before. Unfortunately, that is possibly inaccurate since my driving between the two periods has not been the same, i.e. not the same highway versus around town versus country.
 
Oddly, the Dak turned in it's best all city tank at 19.13 just a few weeks ago. That was before we got the real hot weather. Since then the air conditioning has been on almost constantly (I melt easily!). Nothing kills gas mileage on my Dak better than running the air.
 
Bests,
Dusty

Hi. I have a 2002 Dakota CC SLT+, 4.7, 4speed auto, 3.55 LSD w/255/70 tires. I have owned this vehicle since new, currently about 46,000 miles. I drive about 60/40 city/hwy, 13 miles to work. My mpg is anywhere from 14.5 to 17.5, maybe 19 all highway. Anyway, I have installed Gibson headers, a K&N intake, a soft bed cover, Supertuner programmer & Magnaflow cat-back. I have driven this truck completely stock, with just the headers, just the intake, with & without the cover, with & without the tailgate on/open, and every other combination I could think of, for weeks at a time. The only things I have found that truly affects gas mileage is:
1. My right foot.
2. The temperature.
3. The altitude.
The computer tuner makes a noticeable improvement on acceleration, but can't tell a difference otherwise. I can't believe that a 0.1 mpg difference is a measure of anything, since you can't fill the tank to exactly the same level one fill up to the next.
When is is very hot or very cold, the mileage goes down.
When the altitude gets higher, the mileage goes up, and noticeably. I'm sure that is a function of the computerized F.I. system, and common on most autos.
Also, this thing is an aerodynamic shoe box with a brick on top.
None of the modifications I have made have had any impact on mpg. When using the K&N, oil does get sucked into the engine, which you can tell if you ever pull the air box of the throttle body. Now I am back to stock, except for the bed cover. The 4.7 is so well designed, bolt on stuff just isn't going to help anything, especially gas mileage. Put your money into weight reduction if you really want an impact.
Also, I used to have a '97 Dakota, which was almost identical, except it had the 3.9. The gas mileage was no better than the 4.7.
Just my 2 cents.Thanks.

Kapbot,
 
I agree. Not much is going to have an effect on the mileage.
  I have just purchased an 06 Quad Cab 4x4 with the 4.7. Just hit 1000 miles. 16.9 mpg is the average so far.

thinkin of 2000 4.7 v8 4x4- not sure if 18 is to expect or 12 by dc_gruesome

I'm lookin to buy a 2000 Dak with the above features- I've looked on many forums and have gotten different results. For instance this forum mostly says the its feasable to achieve 19-20 mpg when others dont report anything better than like 14 mpg. Is that because of redline, or should it be close to 18 just as a stock vehicle? As i said ive heard everything from 11- 22 mpg- any ideas or actual facts.. and if 20 mpg is possible.. what did you do to achieve it and how much did it cost to do such?
Thanks

You did not mention what TRANSMISSION you are asking about. I have 2000 Dak with 4.7L and can acheive about 23 MPG on the highway. (MANUAL xmission orderd from factroy!)
 
I used to get the window-sticker MPG of about 18... but when I replaced the fluids with REDLINE oil, the reduction of oil-churn and friction gave me an instant 4-5MPG increase. (Xmission, Xfercase and both differentials) The other bonus is that I may NEVER have to change these fluids again and the manual xmission shifts better than ever.
