#22 of 25 2000 4.7 4wd - Averaging 15~16MPG

We recently purchased a 2000 Durango, 4.7 w/4wd. I was worried that we were not going to get better mileage than the 15 ~ 16 we are. I have tested it several times now and each time it gives me 15.5 to 16 MPG. Only thing is, that is with me driving. When my wife drives, it drops to 13. My '97 Dakota is a 3.9 V6 4wd, and it gets about the same mileage when I drive it. I guess I should be happy. Our Durango was getting about 4MPG due to the PS pressure switch issue. But disconnecting the O2 sensor solved that and brought it right up to where it is. By the way, we have 31x10.50 tires on the Durango. So the odometer/speedo reads less mileage than actual. Technically it is getting even better mileage.

You're doing fine, but your wife may have a lead foot, palpitate the throttle, or not know how to use the cruise control. Before I fixed the suspension with non-stock shocks the truck would bounce up/down in the front especially so much that I found it causing throttle pumping no matter how steady I tried to hold the gas pedal. Using cruise when possible avoids that happening.
I would not recommend disconnecting the O2 sensors or letting them get bad. My mpg got better w/ new ones installed, and the default program in the engine control computer with bad or disconnected O2 sensors increases gas flow to avoid overheating due to a lean mixture, and this excess fuel will foul the cat converters more quickly=>$$$, reduce horsepower, and overheat the engine, etc.
FYI - looks like Dodge finally got this motor right in '09 with new heads. Over 300hp, fatter and better torque curve, and better mpg. Why 9 years to do this?

I towed a 2500 lb popup camper for years with my 2006 DD. Got 15-16 mpg with it. Just upgraded to a 28foot travel trailer (supposed to be 8600lbs) and got 11mpg on the highway but the car towed like a champ even though I know we're pretty topped out at the weight limit. No huge mountains between here and the beach... only a few minor uphills. Was pleased at how well it worked out. I didn't push the speed, held it at 55 mpg and even in cruise control (with the tow haul button on) we did just fine. 5.7 L hemi and tow package.

I have a 2005 Durango SLT with Hemi. I put an K&N Cold are filter system on. I got 22 MPG highway from CO to ID and back at 75 MPH over the 2000 Miles. I see up to 24 MPG depending on speed and driving conditions.
I have just started pulling a 6500 lb trailer 28' Jayco and I'm getting so far about 10.5 MPG. About to take a 3000 mile trip and we'll see what we get. Last year I pulled a 25' Ultralight and got a combined 12 MPG between No. CO and Jackson Hole, WY.
No complaints on MPG. By the way I get 16-17 MPG in town. It seems to love the highway.
