I rented a 2008 (might have been a 2007) Altima two weeks ago, and now a 2009 recently and drove almost identical routes: about 1200km round trip from Brockville, ON to either Secaucus, NJ or Princeton, NJ. As close to 100% highway driving as you get, with several long hills as one crosses the Pocono mountains. The 2007/08 reved at about 2400rpm at 70mph (110 km/h), had enough horsepower to get up these grades without downshifting and got around 32mpg for the trip. The 2009 reved at just over 2000rpm at 70mph and got 35mpg and produced noticeably less engine noise and still did not downshift on the grades. I assumed if they increased their OD or final drive gear ratio on the 2007/08 it could improve mileage without harming highway performance, and sure enough it did. They also improved the speedometer light colour and contrast so that it can be more easily read with either sunglasses or sun glare, which was certainly needed. Especially for the inside set of numbers (mph on Canadian vehicles). |

| Just returned from a 1500 mile trip from Atlanta to Baton Rouge and back in a Hertz rental with 7500 miles on it. Averaging 64 mph over the whole trip, about 85% highway. On highway average speed was right at 80 mph, using cruise. According to the computer and my calculations, averaged just over 30 mpg using A/C about 70% of the time. Loaded with about 300 lbs. of cargo in addition to my 260 lb. self. Was very impressed with the mileage as well as the highway speed acceleration with the CVT. Not rally a big fan of CVT's but it is obviously an efficient transmission. By the way I make this trip frequently and have made it in an '07 Accord (4cyl auto) and Camry LE (4cyl auto), both averaged about 28 mpg on this trip. The Altima provides superior performance and economy to both. | |

I have been to the dealership 4 or 5 times. I am losing mpg on the highway . I am only getting 21 to26. The dealerships keep say there getting no codes. The engine sound good but the mpg keep droping.I heard adding pure acetone will increase mpg , but I am not sure what it will due to the engine or sensors.

| I recently purchased an 09 Altima 2.5s in Post Falls, ID and then drove it home to Fairbanks, AK. Hiway mpg is running 31-32 and suburban commuting about 26. This is calculated brim full to brim full mileage, not the computer. The computer tends to be optimistic by 10%. Not bad but it needs a good diesel engine which would get around 45 and I would change to in a heartbeat. I did look at the Jetta TDI's but concluded I would save enough on the car to buy a lot gas. | |
