    I bought a 2004 Dodge Ram with 4WD and the hemi V8 this year, the MPG has been terrible, average about 7-8 all the time!! no change in towing or when empty?I figure it should be getting about 15 empty. It does have one bad oxy sensor but was told that only accounts for about 1 MPG. Anyone else having problems with their dodge MPG? or know what could be the problem? I always watch my tire pressure and it has a K@N intake and filter which I clean about once a week! i cannot figure what the problem is, but I really regret not getting an Isuzu like I wanted to originally!Thanks guys.

    How many miles? When's the last time you tuned it up, changed the plugs, wires, etc.?

    Is that city or highway?

    For what it's worth, I used to have an 04' Dodge 1500 2x4 w/ the 4.7 & 4.10's and could get no better than 13 no matter how I drove. I'm not a floorboader, but I'm not grandma either. The early hemi's are nice and powerful, but there thirsty. I would figure this mileage is city driving right?, because it definitely shouldn't be doing that bad on the highway. What gear ratio does it have in it?, 3.54's? That could be sucking a lot of your fuel with the extra power needed to accelerate on those big 20's, if you have them. Combine that with 4x4 and depending on your driving style, not trying to blame it on you. Do you do lots of stop and go? I'm not try to bash the truck because I loved mine, I just went diesel because I get 3 mpg better in a truck that is 4x4, weighs double as much, and has the aerodynamics of a fat lady:laugh:.

    Everybody BS's themselves about mpg on their trucks. Makes them feel better. My F150 5.4 gets 8-12 mpg empty. Thats reality. The big three need some research and design hence the position they are in. Now the guys will tell you how their trucks get 20 mpg towiing a Case 580 and 25 mpg hwy.

    My 99' chevy 4wd 1 ton gets 10mpg empty and 6 with loaded trailor. My 2007 Isuzu Npr diesel gets 11mpg with landscape body loaded. My 94 s10 4wd all purpose truck gets 16-17mpg empty.

    You clean the filter once a week??? I have an airraid and clean it about three times a year. The dirt helps the filter to filter better. Trust me, the filter is not causing your mileage to drop. The truck is heavy. The truck is 4X4. It wont get good mileage just by design. My old F150 was getting 6MPG. That was with a 351C and 4.11 with no overdrive. But I didnt care about MPG because it was a work truck. Get yourself a little economy car like I did. The $$$ you save in fuel will cover the car payments. Truck for work, car for everything else. This is the only good advise that I could think of. I know it is not what you wanted to here, but it is what it is.

    We have a 98 1500 extra cab with the 318 and 105k on it . Fresh tune up filters everything still around 10 mpg . I need to look at the front dif. as it feels like it is in 4x4 all the time. This is one of my boys trucks , as soon as he's out of school I'm going to help him get into something newer , he wants a diesel but I'm trying to push him towards a gasser. At one point we had a 95 2500 with a 360 that got 13-14 all day long in mixed driving but the rest of the truck feel apart so we unloaded it after 2 yrs.

    It does have the big 20' wheels and I have wondered about that causing some problems, I have an older 96 dodge, I wonder if the 15 or 16" wheels from it would fit on my 2004? then i would know if the 20's are to blame. it gets about 10 on the highway empty. The 4WD shouldnt matter when you are on the road because it is not engaged,if i am wrong about this please let me know, but the way I underrstand it when you are in 2 high it is not sending any power to the front axle so that wouldnt effect the MPG? Every dodge I have ever owned which is many have not been good on gas!Youre right, I do need to get a small vehicle to drive around in the off season, but I am so used to driving a full size, I have not driven a small vehicle in many years!

    Unless the 1500's are different from the 2500/3500 HD's in terms of how the 4 wheel works, they most likely have auto locking hubs just like the HD's do. Starting with the 94's, they got rid of the manual locking hubs as it's easier to slap a auto locker on on the assembly line, it's more money to be replaced, makes front end parts wear out faster, and Dodge can advertise "shift on the fly 4 wheel". How it work's, at least how it does on the 03 and up HD's, is the whole front drive train is locked to the front wheel's in 2 wheel while going down the road, but just shifting to 2 wheel on the stick only unlocks it at the transfer case. So as your going down the road, the whole front drive train is turning and the engine is always having to push and turn that as well.
