#189 of 195 2008 altima mpg by char5321 May 24, 2009 (4:12 pm)
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.

Replying to: franny67 (Jun 01, 2009 4:13 pm) I have a 05 2.5s altima and i get about 32mpg thats a mix between city and highway but , mostly its city miles..I use the highest octain gas and add marval mystery oil to each tank of gas.Some times i get higher mileage 34 or so highwway but it never goes under 27mpg in the city.I reset my miles every time i fill up and this last tank i got 448 miles and put 14g in the tank and had 6g left in the tank before i filled up.its was near empty when i filled up.And i always use shell gas nothing else..
#193 of 195 First 4000 miles MPG on 09 Altima by boodrow Aug 22, 2009 (12:05 pm)
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.

Replying to: char5321 (May 24, 2009 4:12 pm) I also have an 06 2.5 and get 24-27 fillup-fillup driving all highway. Not anywhere near what the sticker said. Now Nissan quotes 25-27 Highway. That is about $8000.00 more for gas over the life of the car. Jim
#195 of 195 2009 Altima 2.5 mileage by freezed Sep 25, 2009 (6:11 pm)
2009 2.5s, 6M, 7900 miles. Computer shows 32.2, which is right on target with my calculations. Very satified with the mileage and the range of this car. I'm not hypermiling or anything, though I drive the interstate a lot, I spend most of the drive between 75-80 mph.
