2009 Nissan Murano Fuel Efficiency: The Truth From Owners
The 2009 Nissan Murano delivers real-world fuel efficiency averaging 19-22 MPG combined, falling short of its EPA-rated 18 city/23 highway by 1-3 MPG according to owner logs from Fuelly and TrueDelta, with front-wheel-drive models hitting 22.66 MPG and all-wheel-drive versions dropping to 19.21 MPG due to added weight and drag.
Official EPA Ratings
The Environmental Protection Agency rated the 2009 Murano at 18 MPG city and 23 MPG highway for all trims, yielding a combined 20 MPG, unchanged from the prior model despite a power bump to 265 horsepower from its 3.5L V6 engine paired with a CVT transmission. This rating applied uniformly to front-wheel-drive (FWD) and all-wheel-drive (AWD) variants, a rarity since AWD typically incurs a 1-2 MPG penalty. Manufacturers claimed these figures under standardized 2008 EPA test protocols introduced to close the gap between lab results and road reality.
Independent tests by Motor Trend and Car and Driver corroborated the highway figure at 23 MPG but noted city driving often dipped below 18 MPG under aggressive acceleration, with the CVT's "gear-on-gear" simulation aiding smoother power delivery. MotorWeek's mixed loop achieved 21 MPG on regular unleaded, praising the engine's efficiency for a midsize crossover weighing nearly 4,000 pounds.
Real-World Owner Reviews
Owner-reported data from Fuelly, aggregating 2.5 million miles across 73 vehicles, pegs average MPG at 19.08 with a tight 0.07 margin of error, after excluding 5.87% outliers like idling or towing. TrueDelta users logged 22.66 MPG for FWD models driven 42.5% highway at 64 mph averages, versus 19.21 MPG for AWD on mixed city/suburban routes with light throttle. These figures reveal a consistent 1-2 MPG "mpg gap" from EPA ideals, attributed to real-world factors like traffic and climate control use.
"The Murano's CVT shines on highways but guzzles in stop-and-go, averaging 17 MPG city for me over 50,000 miles," reported a Fuelly user on March 23, 2025.
Australian reviews from CarsGuide noted 10.9 L/100km (21.5 MPG) combined claims, but real consumption hit 12 L/100km (19.6 MPG) in urban tests, aligning with U.S. data. Edmunds calculators estimate $233 monthly fuel costs at 20 MPG, 42% above average midsize SUVs.
Fuel Economy Comparison Table
| Model/Drivetrain | EPA City | EPA Hwy | Combined EPA | Real-World Avg (Fuelly/TrueDelta) |
|---|---|---|---|---|
| 2009 Murano FWD | 18 MPG | 23 MPG | 20 MPG | 22.66 MPG |
| 2009 Murano AWD | 18 MPG | 23 MPG | 20 MPG | 19.21 MPG |
| Fuelly Fleet (73 cars) | N/A | N/A | N/A | 19.08 MPG |
| MotorWeek Test | N/A | N/A | 21 MPG | 21 MPG |
This table highlights the mpg gap, where real-world data trails EPA by 1-3 MPG, with FWD outperforming AWD consistently across sources.
- Fuelly's 8,428 fuel-ups over 2.5M miles confirm 19.08 MPG baseline, robust against outliers.
- TrueDelta's driving habits survey: 64 mph highway bias boosts FWD to 22.66 MPG.
- Edmunds: 7.3 tons annual CO2 at 20 MPG, 24% above SUV average.
- Australian tests: 10.9 L/100km claim (21.5 MPG) vs. 12 L/100km real (19.6 MPG).
- Car and Driver: 18/23 MPG tops class despite 178-ft 70-0 braking.
Factors Influencing the MPG Gap
The CVT transmission, Nissan's Xtronic with 7-speed shiftable modes, optimizes efficiency on steady throttles but struggles in city grids, per MotorTrend's canyon tests. Added mass from the updated D-platform-torsionally 50% stiffer-increased to 3,875 lbs, offsets the 20-hp gain to 265. Owners cite AC use (on 50% of miles) and flat terrain as variables closing the gap to 1 MPG.
- Review EPA labels from January 2009 on-sale date for baseline 18/23 MPG across S, SL, LE trims.
- Log personal fuel-ups on Fuelly for 2,495,220-mile validated averages.
- Test highway at 64 mph for peak 23 MPG, avoiding heavy traffic (10.1% of logs).
- Compare AWD penalty: Add $1,600 but lose 3 MPG in snow.
- Budget $233/mo at 15,000 miles/year on premium alternatives, though regular suffices.
Historical context: Launched January 2009 amid oil spikes to $147/barrel in July 2008, the Murano's unchanged MPG drew praise for value at $27,075 base.
Owner Quotes and Long-Term Data
"Achieved 21 MPG mixed after 100,000 miles; CVT holds up if serviced," per MotorWeek's 2009 road test updated 2022. TrueDelta members note suburb miles at 0% in samples, emphasizing highway for best returns. CarsGuide's Smithy endorsed reliability: "Little goes wrong if serviced," with 191 kW V6 sipping 10.9 L/100km claimed.
"Fuel economy-18 mpg city, 23 highway-is at the top of this class," Car and Driver, 2009.
Performance vs Efficiency Tradeoffs
The 3.5L V6's 265 hp propels 0-60 in 6.9-7.4 seconds, quarter-mile 15.4-15.7 at 92 mph, but at 126-178 ft 60-0 stops. This sporty bias-faster than 2003's 7.5-second sprint-explains city shortfalls versus highway parity. AWD adds grip without MPG hit under new EPA rules.
Versus rivals: Beats Toyota Highlander (17/23 MPG) on paper, matches in reality per Edmunds. Australian Ti trim's Bose nav couldn't offset 12 L/100km urban.
- 265 hp/248 lb-ft V6 unchanged efficiency from 2003 despite +25 hp.
- CVT re-engineered for 9.1% better consumption Down Under.
- BOSE 11-speaker distracts from pump pain.
- $27k-$36k pricing undercut segment in 2009 recession.
Economic and Environmental Impact
At 20 MPG and $3.50/gallon (2009 average), annual costs hit $2,100 for 15,000 miles, 36% above efficient SUVs. 7.3 tons CO2/year trails class by 1.4 tons. Owners value styling over sips, per LA Times' March 26, 2008 preview.

Key concerns and solutions for 2009 Nissan Murano Fuel Efficiency Reviews
How does AWD impact MPG?
AWD variants lose 2-3 MPG overall due to the power-sapping transfer case and heavier drivetrain, with TrueDelta showing 19.21 MPG versus 22.66 for FWD. Owners in snowy regions accept this for traction, but FWD suffices for most.
What's the city/highway split in reviews?
City MPG averages 17-18 from owner logs, highway 22-23, with 26.8% urban miles dragging combined totals down per TrueDelta's breakdown. MotorWeek hit 21 MPG mixed.
Does premium fuel improve MPG?
No significant gains; regular 87-octane yields EPA figures, though some owners report 1 MPG bump on 91.
Is the MPG gap worsening with age?
Fuelly's 2025 data shows steady 19.08 MPG on high-mileage units, crediting V6 durability.
How to maximize MPG?
Maintain schedule per CarsGuide; use eco-modes; highway cruise at 64 mph.
Worth buying used for MPG?
Yes, if serviced; 19 MPG holds post-150k miles per Fuelly.
