I have had my D2 since Labor Day 2006 and I enjoy the truck, but the 11.5MPG average I'm getting around the city is a bit to swallow. Anyone have any tips for improving fuel mileage other than running higher tire pressure?
I have a few road trips planned for the summer, I dread seeing the mileage once I begin pulling a 6x12 enclosed motorcycle trailer loaded with gear.
Just curious,
Ken

Ken, for all the great things the D provides, MPG isn't one of them. The best method to gain improvements are a good tune up and a light right foot. You can open up the air flow, etc but while that helps it also adds HP and you're right back where you started.

take it out of 4x4? The new D is all wheel drive. The only options are 4x4 low and 4x4 lock

Some models aren't like that.
Unfortunately as Indy Stated these aren't real gas misers

best thing I found for fuel economy isn't to drive it? I don't mean to sound like a D!ck but I'm serious. we drive my wifes mazda3 places because the Hemi is just too damn thirsty

since this model is all wheel drive, and if you don't need it. then you can remove the front drive shaft.

The consensus here, if I'm not mistaken, is that it won't make any difference?

I'm not familiar with the new models and the 4 wheel drive, but if it's set up so there's a drive shaft, then yes, it should make a difference. technically, it'd still be in 4 wheel drive, but since the driveshaft is gone, the power won't be getting to the front wheels which means it won't "suck" the power.

yes and no, yes mileage will increase a little but since it's awd it'll have the transfercase still engaged still sucking power and fuel

One of our members who has an RT has already tried the front driveshaft removal idea, and he reported that although it made burning up the rear tires quite easy, there was little to no mpg increase depending on the driving style.

My theory in support of those results is that the additional weight of the 4x4 components is still there excepting the front driveshaft. The weight of which is neglible on a 4800 lb vehicle having the aerodynamics of a brick. Since our Durangos don't have any kind of locking hubs, the front shafts and front ring/pinion assembly are still there providing some amount of drag.

I haven't had the chance to do any mileage comparison on my D since it became AWD in Feburary. I can state though that it hasn't changed any around town, ie still very thirsty.

Don,

Is this a brand new D or are you referring to the 2001 in your avatar? If its the 2001, check your o2 sensors. They could be causing you to run rich? :? :?

If its a new one, well?keep right foot at bay. Er like everyone else said. I know?The sound and feel of power will tempt all of the best of us.

Oh OH sounds like the Tim " the tool man" syndrom coming out? Errrr Errrrrrrrrrr ERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR. :cheesy: :mrgreen:

And the wheels are still turning front axles and the diffs.
