Among all of the factors that affect mileage that have been mentioned here, the one that is probably affecting you the most has not been mentioned. That is weight! You have AWD which adds about 200 lbs, you may have a sunroof which adds over 100 lbs, and you may have several other options which in total could add even more weight. I have the base model with the base engine and I am getting about 16-17 city and about 28-30 on the hwy. My car weighs about 400 lbs less than yours. Thats like you carrying 2 adults with you wherever you go. This will greatly affect your mileage and is not taken into consideration in the EPA estimates. Now, I also live in Florida, which is at sea level, all roads are flat and the weather is nice all year round. So, everything works in my favor. BTW, you might also try a different gas station, I read an article recently which stated that there was a bigger difference in mileage among different brands of gas than is commonly believed.

Saddle soap and a soft cloth is far superior to dish soap and a paper towel.

I have a 2009 RWD with the standard engine and automatic (6100 on the odometer). I drove from Indiana to New Mexico and back (cruise set at 5 to 8 mph over the posted limits all the way), and I got 26.3 mpg for the trip using the miles driven divided by fuel used pencil and paper calculation method. Incidently the onboard computer gave me the same result as my pencil and paper.
I would suggest that 8.5 miles is a very short commute. My onboard computer always registers my worst mileage for the first 3 to 5 miles of any trip.

I had a chance to see the CTS Sport Wagon tonight at the South Florida Auto Show. I have to say it is the best looking wagon I have ever seen. My only concern is that the blind spot by the D pillars is enormous!

I've had numerous cars with big blind spots, think old days when fastbacks like the Mustang were the rage and you learned to live with it and work around it with your mirrors and common sense. Think about the guy in the 18 wheeler, now there is a huge blindspot but they learn how to drive and have a lot less crashes per mile than the average joe six pack

I drive the same DI AWD. My commute is 12 miles one way and I only averaged 16 to 17 mpg on a tank. I now have over 16k on the car. I did not see better mileage until I hit about 15k. I am now getting about 18 to 19 mpg. The one thing I did notice is I get better mileage without using the AC. I talked to another guy today who has the same car. He started out just getting around 14 and is now averaging 17. He had not one complaint about his car....he, like me just loves it to darned much to say anything bad. My only complaint is the dealer requires anywhere from 2 to 6 times to fix a warranty repair.  From sunny Palm Springs.....

Cadillac Touring Sedan [CTS]

I have not seen or heard what CTS, STS and DTS represent.
I came up with what seems reasonable:
1. CTS, Cadillac Touring Sedan
2. STS, Sport Touring Sedan
3. DTS, Deville Touring Sedan
Has anyone seen information from General Motors?

I dunno if there is any official explanation. But working backwards, the DTS evolved from the DeVille so that makes sense. The STS evolved from the Seville so I suspect that the Seville is what the first letter stood for. To my knowledge, the CTS was designated as that from the start as the replacement for the Catera, but I don't think GM wants to remember that name, so maybe it just stands for CTS.

Well, perhaps I have less reason to be concerned. I have a 2009 CTS DI RWD. I'm nearing the 1000 mile mark and I've been averaging 15.5MPG. My main commute is 21 miles each way with a fair amount of congested highway each way. The thing that concerns me is that, driving pretty much the same way as the 96 Accord I replaced, I'm getting much worse mileage than I expected. WIth the Accord, I'd average around 25MPG. The CTS averages 10MPG worse, but only runs about 4MPG worse on the ratings.
I love the car, but filling up about every 270 miles is pretty painful.

not to add to your frustration..but if you have to be concerned about filling up the $40K cadillac over a honda.....then perhaps you should have stayed with Honda....was the honda a 4-banger..manual or auto?
21 miles in congested traffic..highway or otherwise will dramatically impact MPG,,you will not see high 20's in the CTS until an extended highway road trip....in northern va....im averaging 22-23 around town with stop and go....and 28-30 on the highway....over 100 miles steady highway driving at 70 plus..09 with 4k on it none DI engine
