How's your Lucerne MPG?
Jul 11, 2006 (5:05 pm)
I have a new 2006 Lucerne CXL V8 with about 750 miles on it. I've checked my city mileage twice and both times it was around 14.2 MPG. Haven't had a chance to check it on the highway mileage.

My Lucerne CX is just a week old with 532 miles on it.
One highway test,(210 miles round trip)used just
7.25 Gal or about 29 MPG,for this full size car!
I will update again as I have
longer trips planned. The best compliment I can give is
that the Buick Lucerne is exceeding my expectations.

Last weekend we took a trip and on the way home got as high as 33mpg cruising at 60mph. Overall for 450 miles we averaged around 31mpg. Not bad for a full size car!

We are visiting the gas station LESS often!
Our new Lucerne CX definitely uses Less gas than our old
1994 Park Ave that had 30 HP. less power !
For a full-size car the highway mileage of 29-30 MPG.
and city mileage of 20, (or more) exceeds expectations,
while providing a really quiet and comfortable ride.

My CXS 70 MPH comes in at 26MPG. I am using 89 octane fuel and would be interested in seeing results using 87 & 93 octane. City mpg varies on who drives the car, between 15 and 18 MPG.

Just got back from vacation. Today we averaged 67.6mph for 245 miles (all interstate) and the DIC said we averaged 32.3 mpg. Could NOT be happier with the mileage so far!
#8 of 106 Any further updates?

I'm especially curious about those of you that own the Northstar V-8 model.
#9 of 106 Outstanding V6 fuel mileage!

My 3.8 L CX consistently gets 30 -31 mpg at a cruise-controlled 75-80 mph. I know of no other non-diesel large car that gets this kind of mileage. And the V6 is not in the least underpowered. Smooth and quiet too.

I agree 100%, I get the same kind of mileage with my CX. Over 500 miles on a tankful in a comfortable full size car is hard to beat.
