Winter is really hard on gas mileage, mostly because engines rarely get a chance to warm up (and that means the oil, not the coolant) completely. I drove a car in Alberta for awhile that had an oil temperature gauge, and it can take an hour or more to get the oil to a stable temperature when it's cold out, and even at that, the oil temp is lower than when the air temp is higher, as in the summer. Add to that the fact that "winter-blend" fuels rarely do anything positive for MPG.
I've done a fair amount of long-distance driving out here in the wide-open west and watching the average MPG number continue to go up for an hour or two on long flat stretches in Nevada, has be convinced that getting too worked up over poor gas mileage in the winter where it gets really cold is not a good plan.
See what happens next summer on a long trip.
I have had 4 Eldorados and 2 CTSs and all got the EPA MPG with this Instant MPG test and they all would show 60-70 MPG after taking foot off the gas and coasting. More miles, summer gas, etc, will help, but it sounds like you are so far below the highway EPA, that something is wrong. After this test, you have some facts to discuss with the dealer. Talking with the dealer about average MPG and city MPG, isn't going to get much done.
You could have something weird, like a brake rubbing, especially if it doesn't get good MPG on instant when coasting. Check your tire pressure.
And,.. yes going down hill coasting it would shoot up to 70MPG on the instant read out.
Tire pressure seems in line.
I'm still getting the same mpg. Nothing I do seems to change. If I drive as conservative as possible, the best is 13 MPG. If I get on it and use the sport mode, I'm looking at 10 or 11 MPG.
I'm going to take this baby back to the dealer again.
I have notice other post regarding rough idle. I also have the same issue. For a 40k plus car, I am shocked how this thing sounds. I forget about it right up until I get out of the car while it's running. It always makes me double take and think something is wrong. I don't mean to whine.....
I think the car is sharp and like a lot of the internal features, but I'm beginning to think I should have done more research before buying.
I'll also try to find a gas station that isn't 10% ethonol. I haven't been paying attention to that.
Thanks for all the comments and suggestions.

It does sound like something is not right with your car. Plenty of others have reported expected EPA MPG. Stop and go driving can be bad, but highway cruise should be better than you are getting.
Sport mode would hurt gas mileage.
Instant mileage is only a picture of mileage at one instant in time and should not be used in any mileage calculations. It can be manipulated too easily.
When I fill up my CTS, I zero the average mileage on the DIC and drive for at least a tankfull, before checking my average. If I'm taking a long highway trip I don't check the mileage until the entire trip is complete.
Most of the time I will go at least a month and multiple fillups before checking mileage. It gives you the true picture of your cars performance over a period of time.
As I've said before, engines need break in time before they give the best mileage. If you have under 10K miles, don't panic. Drive the car and enjoy it, you didn't buy it solely for the mileage did you?
I do have a 3.6 DI engine.
Performance?
When I first took the car back, the dealer set me up with CTS 09 263HP RWD as loaner and I noticed that it seemed more responsive (peppier).
Besides the MPG, this is also an issue for me.
I'm basically following the dealers initial advice and adding more miles to see if any thing changes. I manually calculate my MPG after every tank of gas. It's pretty much a tank a week for me. It's great to hear what others are experiencing and thoughts on causes. This will all be helpful when I discuss my issues with the service dude in the future. Thanks all!
".... you didn't buy it solely for the mileage did you?"
No, actually the CTS seemed to get good reviews and I honestly thought it was a sharp car and wanted to go American. The sticker MPG seemed reasonable, so I did even think about it. My last two were German, and never thought about MPG, because they seemed to get what was noted right out of the gate.
Oh, well I don't want to beat a dead horse, I'd be happy with MPG close to what's noted on the sticker. Thanks for your thoughts.
I did notice this past week that my MPG increased by 0.3 MPG - perhaps due to change gasoline (no more winter blend?).
When - as the near the end of the assembly line or as they get on the truck to the dealer?
An engine needs a break-in period for the rings and valves to set themselves. During that period, most drivers will notice an increase in the average MPG, optimizing at 8 to 10 K miles.
So what if we buy an extended warranty through a 3rd party? Would that cover it?
I have not had a chance to do a long highway trip with my CTS09 AWD 3.6 DI.
My latest has been 120 miles Highway ( moderate hills), average 70MPH and then the rest city driving.
254 miles to the tank 15.7 gals = 16.2 MPG.
Oh well,.... perhaps the AWD 3.6DI combo is the real hog. ;(
It still looks cool. I will not tell my green friends...
Anybody out there with my config seeing similar results?
Thanks.
I'm with you. I love driving manual transmission. I received the same reply in the Boston area when I inquired about a manual trans. Same deal, one sales dude said to me no one would want one of those, right after I asked him about it. After that comment there was no chance I'd buy anything from him.
OK, I did drive a base CTS 08 manual trans and found it to be a little clunky. I really wanted to love it. I ended up getting AWD 3.6DI automatic. I play with the Sports mode sometimes(watch out 10 MPG) , but I do miss the manual trans. I will turn back to the dark side on my next car.
good luck.
Each manufacture uses the same test to get their mpg on all vehicles, nobody drives at 50 mph on the hwy.
On the taxe, I head the date or the taxes write-off was 1/1/09. There had been talk of making it back to Nov/2008 but that got killed and the last I heard was if you bought in 2009, you would be able to deduct it.

Problem: The digital time does NOT display in any screen on the Nav System Radio display (not in Audio, not in Nav, etc.) except in the Config screen, a screen not in use except for configuration purposes.
Is there a way to have the digital time display on the Audio and Nav screens (I tried every setting and can't get it to display). If not, then why have a digital time setting?
On my '06 STS V-8 Nav Radio System the similar digital time function displayed on all screens in the upper right, a spot reserved for the outside temperature on the CTS Nav System Radio display.

Hope this makes sense - that's how my Acura does it. I don't have a CTS. Just monitoring this board b/c I'm thinking of getting one.
Sorry.
THE KEY WILL UNLOCK THE DRIVERS DOOR AND LOCK AND UNLOCK THE GLOVE BOX.
JUST HOLD THE BLACK BUTTON IN THAT IS JUST UNDER THE KEY RING AND PULL ON THE KEY RING. THE KEY WILL COME OUT OF THE REMOTE. IF IT HAS NEVER BEEN OUT,IT MAY BE A LITTLE HARD THE FIRST FEW TIMES,THEN IT SHOULD GET EASIER. I RUBBED A LITTLE SILACONE SPRAY ON THE KEY. TAKE THE KEY WITH YOU WHEN YOU LEAVE THE REMOTE WITH THE VALET PARKING.
AS FOR THE TRUNK,THAT IS A LOST CAUSE. MY CAR HAS DROP DOWN REAR SEATS,SO ALL YOU HAVE TO DO TO GET IN THE TRUNK IS DROP THE SEATS DOWN. IF YOU DO NOT HAVE DROP DOWN SEATS ALL YOU HAVE TO DO TO ACCESS THE TRUNK IS TO DROP THE REAR CENTER ARMREST. OPEN THE PASS THROUGH DOOR AND REACH IN AND PULL THE EMERGENCY TRUNK RELEASE,SO I DO NOT BELIEVE THERE IS ANY WAY TO SECURE THE TRUNK.

Sad.
Hopefully the CTS isn't starting down the path to oblivion that the Lincoln LS paved 6 or 7 years ago when they got rid of the manual transmission. Note: the Lincoln LS is no longer in production.
