So on the drive to work my mpg AVG was 20.9 after about 26 miles the next time i looked at it it was saying 43 mpg and then it started "syncing" with the instant mpg bar graph just not as quick as the bar moves. By the time i got to work it seemed to level itself out as if its working correctly.
Have any of you had this happen before? Should i take it to the dealer?

Another thing i noticed sunday night was when i disconnected my trailer my left license plate went out so i pluged it back in and the light came back on so i disconnected again and the light stayed on this time. Im thinking it may be a fluke or a bad ground? Is there any way these 2 issues could be related?

I've been experiencing the exact same thing you have.
On the way in to work this morning, I noticed the EVIC displaying 21.9 L/100. I reset the EVIC. Display was reading 75.x L/100, then came down to a more reasonable 17.x L/100. Then it came down to like 11.x L/100 and slowly crept up to between 14.x L/100 and 17.x L/100.
Sitting idle at a stop light, I noticed the EVIC creep up. First it read 17.8 L/100, then a few seconds later it read 17.9 L/100 and then 18.1 L/100, etc. I realize the L/100 should change as I idle, but that quickly?

How can I go from 11.x L/100 to 17.x L/100 in under 1 km? On a 121 Litre tank I am reading 591 km (DTE) at full. In the summer my EVIC was reading well over 750 km (DTE). What the heck? The last tank fill read 520 km (DTE)!!!!!! That's some pretty lousy gas mileage.

When the truck was new the EVIC would show between 20.x and 21.x L/100. Then I went on a road-trip to B.C. and was averaging 11.x and 12.x on the highway. Pretty impressive, I thought. City driving was around 14.x and 15.x in B.C.

Now, at just under 10,000 kms, I am averaging around 19 L/100 in the city.
Very frustrating.

But, seriously, getting 520 kms city driving from 121 Litres seems a bit on the PIG side.

Anybody else seeing this?
Suggestions?

My EVIC doesn't do the calculation fluctuation thing but since November my mileage is almost identical to yours. I think the combination of winter fuels, idling time and slower than normal city traffic all take their toll on the Hemi. On good long highway runs my mileage does get back to summer numbers. In talking with a buddy of mine that also drives an 11 Ram, his numbers are identical to what we are getting. He said his 09 was the same and bounced back in the spring. I've always experienced horrible mileage in the dead of an Alberta winter.

Hearing this from another RAM owner, I feel somewhat relieved. What puzzles me is how my brother can be getting way better fuel economy over me. FYI: I have looked at his EVIC (in winter) and can confer that his EVIC is reading in the 12.x L/100 range. He warms his vehicle when it's cold (I do too, but for a very short time.)
He has the 89(?)L tank...I have the 121(?)L tank. We both have the HEMI. Mine is the Sport model; his is the SLT model. We both have C/Cabs. I have a sprayed-in bedliner and box cover (he has neither). Can't see that having a drastic impact on mileage.

I'm getting the same mileage I did when the truck was new.

It's 0 degrees here in Edmonton and my EVIC is bouncing around between 12.xL/100 to at least 23.xL/100 (I quoted less in my last posting).

How in the hell can I be using (on average) 23L/100km???????

I guess I should unload the 1500 lbs of rock I have in the box??? Just kidding.
I just don't get it.
I'm wondering what else could be affecting my gas mileage to this degree.
To watch it creep from 11.x L/100 up to 17.x L/100 in less than 1 kilometre is beyond belief.

(Update: I realize it looks like I keep posting different L/100 values. The EVIC has read in-between the 11.x L/100 and 23-24.x L/100 on my daily commutes.) I'm frustrated and get angry writing about my crappy gas mileage. I know it's a HEMI and I shouldn't expect GREAT gas mileage but, I didn't expect to get such crappy gas mileage either.

'Nough said. Outta here.

So this morning on the way in to work the EVIC was fluctuating between 12.3 L/100 and 13.9 L/100!
I just don't get it. Yesterday I was averaging around 19 L/100.
And I even drove a bit more aggressive this morning! Maybe that's the trick.

I'm thinking of getting rid of the '11 and moving up to a '12. Dealer will sell me a 2012 Sport C/C 4x4 (everything but leather seats and sunroof) for $36,750.00
Included as options:
-Tow mirrors, 121L tank, 3.92 gears, sprayed-in liner, anti-slip axle, back-up camera, park assist, 430 Stereo, side steps, sport hood, blah, blah, blah. Pretty much the same price I paid for my '11. I know the 12s get the 6 speed tranny (same tranny, different shift patterns?)

Dealer offered me $30,000.00 for my truck as a trade-in. <LAUGH>

Have to see...
