'03 Quad cab 4x4-4.7 MPG disappointment by bda54
Jan 15, 2008 (10:20 pm)
Reply
About 2 months ago I bought my '03 Quad cab 4x4 w 4.7-V8 and 5spd AT. The previous owner had put 265/75R16's on, up from 265/70R16's it came with. It has a fiberglass topper. I keep about 200-300lbs of tools in the box. Occasionally I pull a utility trailer that loaded weighs about 800lbs. I drive about 70% highway and 30% city. I am deliberately easy on the throttle. Pulling the trailer I get about 10.2 mpg, without the trailer I get low to mid 11 mpg. I checked the air cleaner and it looks brand new. It runs like a top. No fault codes. I realize that winter driving in Minnesota means lower mpg, but not like this. Any ideas on what I can do to increase the mileage. I read the info on air filters by the oil guy, and I am probably not going to change to a K&N cold air setup. I know that weight is a factor, and the tools are affecting my mpg, but 200-300lbs isn't that much weight. Redline lubricants sound interesting from what I've read on your posts. Any suggestions?

2000 Dakota 4.7 Fuel Problem by jutt

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.

Interesting! That seems illogical, and I've always heard the opposite, but sometimes you get a surprise!

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.

Real World MPG by 74b5roadrunner

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.

Premium vs Regular by oscar5740
Mar 07, 2008 (11:12 am)

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!
