Buick Enclave Real Gas Mileage: Pros
YearBody/PowertrainComment
2009 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic AWD		 More than reasonable for a 5000 lb vehicle. Benefits of aero design ( for an SUV ) and six speed transmission both contribute. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 24 - 28 mpg summer highway driving see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 for an 8 passenger vehicle that can tow 4,500 pounds. I cannot complain about 19.3 mpg city and 24.7 mpg highway. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 Better than competition with regular gas see full Buick Enclave review

Buick Enclave Real Gas Mileage: Cons
YearBody/PowertrainComment
2011 0 The fuel economy is abysmal and as far as I know, Buick STILL doesn't offer a hybrid option. The best mileage I've been able to get on long road trips with mostly highway driving is 22-23 mpg. City driving, however, stubbornly stays at 14-15 mpg, no matter what I do! :( see full Buick Enclave review
2009 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic FWD		 Well under (15-20%) below the EPA ratings, though the engine is STILL brand new (<400 miles total). see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 In town much less than advertised. O.K. (18-19) on freeway. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 This is the one thing that is a weak point. at 12-16 MPG, this car could use a larger and more efficient engine. Had GM not folded, there was talks of a hybrid version (which still may come out as a Caddy) which we would definitely buy without hesitation. see full Buick Enclave review

6-speed shiftable automatic AWD		 Car is still in break-in period, but not seeing anything close to advertised mileage. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 Hey, at $4.00/gallon getting only 22 mpg hurts. We take the econo-car most of the time. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 It actually gets great mileage for its size and weight, but hey, its not a Prius. see full Buick Enclave review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 Bad around town see full Buick Enclave review

2009 4dr SUV 240-horsepower 3.0L V6
6-speed automatic FWD		 Coming from a Trailblazer, we like the average of 21-22 MPG in mixed driving, as were used to about 17 MPG. Fuel economy climbs toward the rated 26 MPG the more highway driving we do. see full Mercury Mariner review
2007 4dr SUV 200-horsepower 3.0L V6
4-speed automatic AWD		 For the first almost three years after we got the car, it gave 21+ mpg in town & 24+ mpg on the road. see full Mercury Mariner review
2005 4dr SUV 153-horsepower 2.3L I4
4-speed automatic AWD		 For an SUV with a 4cyl and 4wd I get avg of 22 MPG mixed city and highway. I usually get 23-26 on freeway only. This is good. see full Mercury Mariner review

YearBody/PowertrainComment
2007 4dr SUV 200-horsepower 3.0L V6
4-speed automatic AWD		 For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
