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!

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.

Mass Air Flow Sensor by ronslakie1

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.

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)

Synthetic Oil choices?? by bda54

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?

Anybody have some real world numbers on a HO engine and a FFV engine?

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)

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.

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!
