Maybe the brakes are dragging? Do you drive with both feet? How about the parking brake, could it be hanging up somehow?

It seems to me that if the truck was getting that bad of mileage, that there would be a noticeable lack in performance of some kind.

 

Not sure if its been stated already, or if you have done this, but I would look at the plugs or perhaps replace them and see what happens. Its a cheap fix if it works.

 

As you will find out someday, checking/changing the plugs is not something that you can do in 10 minutes like on most vehicles.

 

In Canada we usually use how many litres per 100 km....I can't wrap my head around that but mines also says 25 and I think 19 but mine is an 09....Now that is per Imperial gallon which is almost a litre more than the US gallon. Weird the US won't switch to metric system and has to have it's own size gallon...lets just all get on the same wagon make life easier. In reality I think we are getting 20 per gallon combined.....US gallon. Not EVIC by hand averaged over 3 fillups.

 

Why they would put the 3.7L V6 in the Ram much less anyone actually buy one is beyond me. The Hemi is rated at the same MPG and the 4.7 is only 1 mpg less. Maybe there is something here I just don't get? I mean to me, the ONLY advantage of a smaller engine would be fuel economy, that just isn't the case in the Ram.

I'm not trying to insult anyone with a V6 Ram here, but I just don't get the logic. Although with my reasoning, I guess the same would hold true about a 4.7 V8...

 

Cost mainly, and fleet trucks. Hemi was about a 2K option over the 4.7, and if this forum is an example of reality then 90% of people just buy these as big cars and never tow or haul anything (refer to the hundreds of leveling and big dumb wheels threads)

 

Yeah, I really wasn't questioning the 4.7, just saying that if I used the same logic as I used with a 3.7 which gets has no MPG advantage that my same logic would hold true for the 4.7.

BTW, I dunno if it's changed because mine is an '04, but I am a pack rat and still have my window sticker (I have always folded them and stuck them in the owners manual packet with every new vehicle I ever purchased). The option line lists the 5.7 Hemi EFI engine at $795. Although I know in the used truck market around here, it does usually command about $1500-2000 over a 4.7 of the same year and type...

 

On my 2009
5.7-Liter V8 HEMI MDS VCT Engine $ 1,310

 

I wonder if the jump in price came with MDS in '06 or with the 4th Gen an it's increase in HP? Out of curiosity, I may have to check into it.

Without having to go outside, get my window sticker and scan it this is from a review of the '04 Ram I just Googled:

The Hemi produces 345 horsepower and 375 foot-pounds of torque. When properly equipped, that increases the towing capacity to 9200 pounds and payload by an additional 500 pounds. The 5.7-liter Hemi adds $795 to the price.

 

Ahh...yee'll be smockin' a turd in purgatory for dat one Jeep!!!
