I'm getting close to this figure in my '06 Lucerne CX with the 3.8L V-6. A recent trip got me 30 mpg at 65 mph on the open road with an average of 27 mpg overall (80% highway driving). I'm very happy with that in a full-size sedan.

I've been manually keeping track of my mpg since January this year. I commute everday from the outlaying 'burbs of Chicago to downtown (100 miles round trip). With all the construction and traffic backups I'm averaging 22-23 mpg. During the last winter when construction ended I was averaging 24. Haven't taken a real all highway trip yet but I'm curious to see what kind of mileage I'll get.

I think you'll be pleasantly surprised.

My CXL V6 gets about 25 on the interstate. I had a 2000 Lesabre Limited with the same drive train. It got 30-31 on the same route driven the same way.
The car now has 1000 miles and the tire pressure is set right from the beginning. I don't think the engine will loosen up significantly. I know it is a couple of hundred pounds heavier than the old car but is more streamlined to make up for it. I think there is something wrong. I will try again before taking it back to the dealer.
Phone call to dealer resulted in nothing. They said that since the check engine light did not come on, there should not be a problem, and there were no TSBs, but I can bring the car in.
Other than that, I am the happiest I have ever been with any new car.
Any V6 drivers go back to the dealer and get any resolution for better gas mileage?

Are you resetting the mileage average readout on the DIC when you begin the trip on the interstate? I like to reset just as I get on and then watch to see what it's doing.
 
What kind off interstate? Hilly? Level?

Going a steady 60-70 on the interstate I get 31-33 mpg so I have no reason to go back to the dealer. (2006 CX)

Yes, I do reset the DIC as I gas up,{same gas station} about a mile before the interstate. The trip is through Missouri and Arkansas so there are hills. Round trip is 320 miles and it was not windy. I drive conservatively and steadily about 70, the same way I drove the Lesabre.
The Lucerne has the Energy MX4 Plus Michelin, which I assume are known for low rolling resistance.

I have a 2007 Lucerne (6 cylinder) with 3800 miles on it. On a recent trip from Florida to Maine I averaged 25.9 mpg. This is pretty poor since I averaged over 30 mpg on my 2003 Buick LeSabre. Overall, in the last 2500 miles, including the trip from Florida to Maine, with more highway driving, I am averaging 24 mpg. Since most is highway driving, I think thew mileage is quite poor. Bet it averages well below 19 in the city.

Update on mileage.
I now have 5200 miles on my 2007 Lucerne CXL (6 cylinders). I have reset the mpg indicator for my last 1400 miles of driving. My driving is in a small seaside resort with sometimes heavy traffic and country driving along with some interstate. My overall mileage is now 20.3 mpg. My dealer says that is normal for this car. I am amazed at the mileage some people say they are getting, especially since I never gun the engine.

I'm sorry to say that my 2007 Lucerne CXL (approx 6600 miles) does not get the MPG as posted. I drive in the city for the most part and I'm lucky if I can get more than 17 MPG. My '94 Park Ave and '85 Park Ave, both gave me at least 19 MPG. So I am so disappointed, especially now that gas is so expensive, and I'm careful on the gas petal.
