#14 of 23 Re: Fuel mileage when new [ballcoach] by jchappel Apr 26, 2007 (6:54 pm)
Replying to: ballcoach (Apr 07, 2007 7:04 pm) I have an 04 Hemi and my mileage has varied. I used to use it for my sales job and got 17mpg city and highway combined. Now, I drive to and from work and get 13mpg city only. When I tow my 5000lbs boat I get about 11mpg. Highway only I average around 19-21 depending on my speed.

Replying to: tidester (Jul 13, 2006 12:03 pm) I just bought a 2000 Durango with the 4.7 magnum engine, it has 72,000 miles on it. The computer only shows 14.6 but when I filled the tank, i was getting 17 mpg city and received 19-20 on a trip. I have installed a cold air intake and I believe it helped a little if not it sounds great!, I also installed Splitfire spark plugs.

#18 of 23 Mileage and towing experience with Hemi Durango... by ozcop Jul 04, 2007 (8:19 pm)
Looking at buying an 05 or 06 Durango with Hemi and tow package. Has anyone towed a 3000/3500 lb. total weight trailer? Gas mileage both towing and empty, city and highway, on Durango Hemi with 20,000 miles or more would be appreciated... Thanks.

Replying to: jjans43 (May 17, 2007 5:40 pm) 2000 4.7 4x4 semi-aggressive tires 149,900 mi factory underbody rock guards K&N filter insert Splitfire Platinums Helix type throttle body. ALWAYS been around 13.5-13.9 avg, mpg - yes the computer is fairly accurate if tires size hasn't been mucked with too much. Avoid rack loads and big mirrors or slow down with them especially going into strong headwinds - too much wind resistance already with this body design. Going to try Gibson cat back system as other forums seem to think better in better out = better mpg with these pigs. We'll see. Anyone tried Bosch +4 plugs with the normal 4.7? Anything else?

#22 of 23 2000 4.7 4wd - Averaging 15~16MPG by rchii Apr 22, 2009 (8:47 am)
Replying to: steve755 (Jan 11, 2008 12:15 am) 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. Replies to this message: steve755 (Apr 22, 2009 2:49 pm)

Replying to: rchii (Apr 22, 2009 8:47 am) 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?
