Hey Guys and Gals,

I just went thru my first tank of fuel and averaged 21mpg mixed driving. I have the 3.55 rear end and was hoping for a little better fuel economy.

Are other ED owners seeing the same results?

Oh and I live in southwest Michigan and I'm sure we are on winter fuel now.

I just went through my first tank as well and got 20.5 mixed driving. I have a 3.92 rear. I was hoping for better mileage also! I was babying it the whole time.

 

[Smerleau]

Are you on winter fuel as well? I was soft on the pedal as well.

 

[hammer1]

Yup!

MPG in the winter months has seemed to affect mine. It also depends on tire size/tread ect. I found with my SR-A on 20''s gave me better MPG return then the winter tires I have on now, plus warming up or running cold makes the truck use more fuel.

 

[gadfly2]

Warmer weather should bring better MPG. Also make sure your truck is up to date with the "flashes" that the dealership can update.

I live in Orlando and had 25 miles of clear sailing on I-4. So out of curiosity I reset the fuel consumption, set the cruise control at 60, had the AC on low (hey, it's warm down here), and got 36 mpg on the drive home.

 

[Smerleau]

I just bought the truck. Do you believe there are updates already?

 

[gadfly2]

Yours might be up to date, but I bought mine in Aug, and I had two updates installed two weeks ago when they were investigating my MPG (lower then I expected as well). MPG has not been hand calc since the updates, but if the EVIC is correct, nothing has changed. But I'm running in the worst conditions for MPG. I let it warm up for 10 min in the morning, drive 18 km to work, then home again 12 hours later with no warm up.

I have been averaging around 10.4L/100km, which is about 21.5 mi/usgal I think. Not what they say, but wasn't expecting the kind of mileage they claim. It is a lot better than the hemi and F150's get from what my buddies tell me.

Yea, my dad's hemi in the winter is sub 14 mpg. Warming up which is necessary, absolutely kills mileage.

Wow 14 is bad, well I just started getting a weird smell in the cab after truck has been running a little while. :-(

You need to get the truck back to the dealer. Diesel smell in the cab is likely a break in the exhaust system near the turbo. Seems to be an almost epidemic problem that RAM is working on a permanent fix for.

 

[Smerleau]

Shoot ok will take it first thing tomorrow

the smell could be rust proofing from the engine bay being in the air and going through the vents.
i had a few new vehicles and found this to be the case.

Ya give it a couple of highway runs and see if it is consistent over several days.

 

[Smerleau]

took it to dealer and it's just things burning off since its new. They did do three flashes to the truck though and I've only had it 2 weeks. I guess the u connect was one of them.

Fuel mileage is quite variable based on driving practices. If you let things idle to "warm up" that drinks fuel and does not warm up. You cannot idle a diesel and expect it to warm to any degree. You must run the darn thing. Maybe not hard at first, but run with a little load and some rpm.


All my past diesels, including this Eco., took 5 - 10 miles to get up to operating conditions. During that time they all sucked fuel way above their expected fuel consumption patterns. Some of you literally drive to work or whatever and barely if ever get the thing to operating efficiency.


If you only make short runs, you will be better served with a gas engine. Diesel engines like it hot and pulling a load. Simple as that.
