#68 of 104 San Diego to Bend, OR RT mileage... by 0311vn

I put 2500 miles on a Lucerne CX with a six cylinder engine and averaged 25 to almost 28 mpg. I clocked every tank on the trip, which include some mountain driving. City driving dropped to 20 mpg and less on one tank. The six cylinder struck as a bit underpowered. This was rental car with cloth seats.
 
Is it just me, or does the trunk of the Lucerne seem a bit small for a full size car?
 
I would give the Lucerne a B minus overall, a decent grade, but short of the quasi-luxury car I was hoping for when I asked the rental agency for a Lucerne. I would probably go with the V8 engine if I bought one. (Is a Caddilac CTS that shares a platform with a Lucerne that much more expensive?)

I have an '06 CX and love it. Only complaint about the trunk is the arms on the hinges swing down into the compartment and can hit luggage ... something the hinges on the Century we traded in did not do. Other than that, it's fine. There's only the two of us so the size is adequate.
 
Highway mileage is better than my smaller Chevy Malibu. With the cruise set at 65mph I get a consistent 31-32mpg. Granted, city driving takes down the average but once I'm on the highway, it's terrific.
 
The CX starts at around $27000 ... a CTS starts at $35000. Take your pick.

Happy to announce that my 2007 Lucerne CXL (6 cyl) got 27.2 mpg on my recent trip from Florida to Miane. It is an improvement over theprevious 2 trips which were 25.9 mpg.

#71 of 104 Our experience with CX Mileage by scandiaken

We bought an 06 Lucerne CX with a 3.8 V6 engine.
It was during the 07 model year so we got a better price.
It was a brand new car, with 33 miles on the odometer
It now has 10,000 miles.
In 3 trips from St. Paul to Chicago, we have attained
30.3 mpg and once 33.2 mpg.
I calcualte mileage by hand and find that the Lucerne
knows how to calculate mileage as well as me.
When we get on Interstate 94 heading southeast,
I set the cruise at 72 mph.
We love EVERYTHING about the Lucerne with the
exception of the dash lights in daylight hours.
See my blog entries in the interior blog.
I WOULD NEVER TRADE FOR A SMALLER
CAR TO GET A 2-3 MPG ADVANTAGE.

We live 10 miles from the shopping areas that my wife frequents.
Mileasge in these shorter trips is 24.5 mpg.
We are pretty satisfied with that.
Oh, we use the cheapest gas available at 87 octane.
We carry 32 ppi in the tires.
We use 10W30 oil just like suggested in the book.
The tires are what came on the car. Rides fine.

I notice with my CXS Lucerne that you need to pamper your driving habits to obtain good mileage. The sweet spot is around 55mph. Must accelerate slowly and let off pedal to up shift early.
 
I also notice that I achived better milieage after my first oil change - wondering if GM uses a special oil for breaking in the car which may be slightly more friction generating.
 
I now can obtain around 29 -31 on highway at 55 mph without stop and go. Around town milieage is very low.
