What Our Members Are Saying about the Real Gas Mileage of the Nissan Xterra

Nissan Xterra Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2012	4dr SUV 261-horsepower 4.0L V6 5-speed automatic 4WD, part-time w/low range	Most people who drove or owned xterra, complain about fuel economy. I say bs: compare it with its true, truck-based SUV competitors - and there are only 3 of them: toyota 4runner and fj cruiser, and jeep wrangler rubicon. Thats all! All others are not to be compared to xterra - they are just car-based SUVs (even new nissan pathfinder is just a car!).rnWhen you compare xterra with correct competitors, you will find that its fuel economy is excellent: my trip computer and calculations show the best economy of 10.3 l/100km on highway at 95 km/h without aircon, on cruise control, on a warm day. My worst is 19.3 l/100km during heavy winter offroading through 3 feet of snow (and it was quite wet snow), using 4x4 low with lockers. From my comparis see full Nissan Xterra review

Nissan Xterra Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2012	4dr SUV 261-horsepower 4.0L V6 6-speed manual 4WD, part-time w/low range	I don't see how the fuel economy could be improved, given what the vehicle is. But I can't say that I am happy with the poor fuel economy. see full Nissan Xterra review
2008	4dr SUV 261-horsepower 4.0L V6 6-speed manual 4WD, part-time w/low range	Fuel economy is not the best, I average around 15-16 in the city and 18-20 on the highway. see full Nissan Xterra review
2006	4dr SUV 265-horsepower 4.0L V6 6-speed manual 4WD, part-time w/low range	Although the 2005+ gets better fuel economy than the previous incarnation, it won't compete with the light weight car-based CUVs on the market. If you want the strong chassis and off road performance you will feel it at the pump. Off road modifications like extra armor, dual spare tires, larger tires, and gear don't help either. see full Nissan Xterra review
2003	4dr SUV 180-horsepower 3.3L V6 4-speed automatic RWD	Mileage is terrible for an engine of this size and power output. see full Nissan Xterra 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

Mercury Mariner Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
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
