I also have a 2003 Dodge Ram with the 3.7 in it, plus I have a 5-speed transmission. My truck is the 4-door with aftermarket 20 inch rims. The most miles I can get per tank is about 320 around town, but that is when the gas light comes on and it has a few gallons left. On the freeway I can get maybe 380 if I am lucky. I think that works out to be around 14-15 around town and about 17 on the freeway. I always have work stuff in the back of the truck also. But, for how big the truck is, I guess that is not to bad. I might be wrong, but I have noticed also that when I put Chevron gas in it with the techron, it runs smoother and it gets a little better gas mileage. And no, I do not work for Chevron.

I have a very good friend that has a '06 RAM 4x4 Quad Cab with the 4.7 and he averages about 15.5 in daily driving. That's with a short, five mile run to work and back. Another acquaintance says he gets a steady 18 MPG on the highway with his.

11.5 mpg is pretty sorry unless you are driving pedal to the metal in town there Hoss. The 2003 also does not have the MDS (started in 2006) so that may have something to do with it too. Take it easy and see what happens.

Just to clarify, the 4.7 motors never got MDS. That was only available on the Hemi.
 
Since it sounds like you just got this vehicle used, I suggest performing a full tune-up: spark plugs, air filter, clean the throttle body, replace the PCV valve, oil change and new oil filter. I would strongly recommend a transmission maintenance, too, if this vehicle has over 50,000 miles on it. Your's has the 545RFE fully adaptive tranny. All it needs is a new set of filters and replenish the fluid with ATF+4. There are no bands to adjust on this fully electronic unit.
 
I've found tire pressure contributes a lot to good mileage and in some cases front end alignment. There's been a number of computer updates to the 2003, both for engine and transmission and you might find this will help.
 
Overall, however, driving style is the biggest contributor to gas mileage. Gentle launches, gradual increases in speed, lower speeds, and gradual stops make for a often large difference in fuel consumption.
 
Good luck and best regards,
Dusty

No, a CAI at best would only give you +1MPG, IF that much. I have read where you could lose MPG because of the computer trying to adjust the fuel to air ratio.
Your best bet is to go to full synthetics, and look at your tire size. Some are equiped with larger optional tires. Best to go back to the smaller, and skinner tires.
Also, a tune up is in order. Plus, keep in mind, the smaller the motor and the bigger the the truck the lower the MPG. Sure its a V8, but its underpowered compared to a hemi. It has to rev higher and harder to do the same amount of work.
If thats a standard you would get better MPG.

when you say full synthetics are you talking about motor oil only??. I have to say I am on my 5 tank of fuel and I am only avg. close to 12 mpg. thats both local and highway. I have to think I am in need of a tune up. But I still think there is something not right. I have 17 " tires on the truck 35psi in all of them I think they are 245's. Anyway I love the truck just thought I could avg. about 14-15 mpg.
 
                     thanks for any suggestions

You should join dodgeforum.com they have an entire section of people with the same truck and tons of threads regarding MPG.
Full synthetics, I mean, have all oil, such as front differential, rear differential, transmission (if possible, some dodge transmissions will detonate with anything other than ATF4), and of course motor oil. But going from "Dino" oil, to synthetic could cause some slow leaks.
Sounds like you have standard sized tires, I'd look at a tune up, and maybe your O2 sensors. There are many other tips and tricks, but you will have better luck at the forum I mentioned than here.

MPG: Any ideas? by stanoski

Unless you have a 2006 and newer RAM with MDS (Multiple Displacement System), 12 to 13 MPG is all your going to get on average. I have a 2007 RAM HEMI with MDS and I consistantly get 14 to 15 MPG city/highway combined. "But", I drive very lightly too to get this MPG. Your'e supposed to get a 20% increase in MPG with MDS which is about what I get over what you get. The MDS system works as it should.
