#171 of 195 Re: 2008 Altima 2.5 S with CVT first tank [sbb4th] by ken75 May 28, 2008 (5:34 am)
Replying to: sbb4th (May 23, 2008 4:20 pm) This is a continueing story of our Altima 2.5 SL with 2900 miles on it. My wife an I took a trip to northern Wisconsin with my sister,and rather big brother in law with luggage for all of us in the trunk plus cooler and other assorted garbage. We encountered many small burgs where slow down and acceleration was necessary. At no time did I run past 70 mph and at the end of the trip we had logged 512 miles and I still had a registered 1 /4 tank. The highest mileage monitored on the computer was 33.9 mpg and overall after fill up and a check with paper and pencil was 31.2 mpg. The car ran flawlessly, as it should, and is still a joy to drive. My wifes only complaint is the passenger side seat which seems to be uncomfortable to her. Love the car.
#172 of 195 2008 Altima 3.5 SE with CVT by cadgirl May 28, 2008 (5:48 am)
I have found that I am averaging about 25 miles per gallon with this car. I am probably about 60% highway, 40% city (well, small town) driving. I am getting around 380 miles before I fill up, and it's usually between 15 and 16 gallons per fill up.   Over the holiday weekend, I did a LOT of in town driving and noticed a significant decrease in fuel efficiency. I also notice a significant decrease if I don't drive efficiently (slow take offs, coasting to a stop, etc).   My biggest problem with the efficient driving is that I'm coming off driving a Jeep all the time, and this baby takes off with the slightest touch of the gas, as compared to really having to force the Jeep to move. If I'm not careful, I've hit 80 before I know it   Also, my trip computer seems to be just about right on with what I'm calculating ~shrug~.   We are taking it on it's first long road trip in a few weeks (about 500 miles), so I'm looking forward to checking the mileage on a long, all highway trip.   I love the car, though, and while it may not be as good as some 4 cylinder cars around, I love the power behind it, and it's WAY better than my Jeep.

If you wanted a more fuel efficient I4, you'd have to go with a smaller car.
#174 of 195 2006 Altima 2.5 S/SE auto by lorenw May 28, 2008 (8:00 pm)
33.9mpg on last fill-up. 80% highway miles, no speeding, 91 octane gas. The 87 and 89 octane fuel in my area is all now 10% ethanol--I won't buy it because I think I get about 10% worse mpg's with it. I believe I am saving about a gallon-and-a-half on every tankful (about $6.00 worth) for a cost of only $1.50-$2.00 more for the top-grade fuel...net SAVINGS of at least $4.00 per fill-up.   If I could buy 100% gasoline that was also the cheaper 87 octane stuff, I would. Can't get away from the ethanol in the lower octanes at least locally. Replies to this message: ken75 (May 29, 2008 7:09 am)

Replying to: lorenw (May 28, 2008 8:00 pm) I am experiencing similar MPG numbers with our 2.5 SL but I only use 87 octane and 10% ethanol. That little bit of ethanol results in a 3.4 % loss of power and effeciency so I have a tough time with the vehicles operating with optional E85. I have to believe it will really trash economy and power.   For the immediate future the purchase of 100% gasoline will be pretty scarce or until the government subsidy for corn crops is dropped. Not only do the oil companies have our politicians wrapped up but outfits like Cargil, Peavey and ADM have a pretty tight, controlling hold on the purse strings of congress.   Enjoy the car and smile when the guy in the F-350 pulls into the next stall and drops $150.00 on diesel.
#176 of 195 About to pull the trigger on 08 Altima by petrozero Jun 10, 2008 (11:42 am)
Looking forward to posting results here and at the petrozero.com fuel saver forum site. Thanks for everyone who've taken time to post your results. It has sold me on this car! Best mpg short of a hybrid...

Replying to: jd10013 (May 23, 2008 1:49 pm) You're right. I tend to get geo-centric around the boards since a vast majority of posters are from the US.   Sorry!
#178 of 195 MPG update by sbb4th Jun 22, 2008 (2:57 pm)
OK I just filled up my fourth tank. On my first three I really babied it. Slow starts and acceleration etc. My first three fillups ran 26.3, 26.3 and 25.8. This was with about 80% city/suburban - 20% highway. I was satisfied but not particularly thrilled. Then I said the hell with it and started driving the way I've always had with a medium heavy foot to accelerate and then letting off when I hit my speed. The results were 522.2 miles with only 12 miles highway and my mpg went up to 28.3. Now I'm very happy! If you watch your mpg gauge you'll see that after you let off or maintain your throttle the mpgs go up to the 60 mpg mark. The only time you really burn gas is to accelerate and the sooner you hit your speed the better. BTW, 522 miles on a tank is great and I still had 1-1/2 gallons left though the computer said I was empty. By my calculations I could have gone about 570 miles on the tank for virtually all city/suburban driving.
#179 of 195 What is possible by catam Jul 17, 2008 (9:42 pm)
I drive a 97 Altima 2.4L 5spd manual. A year ago I was averaging 32 mpg ( my car is rated at 29 hwy) I started reading about hypermilers, and did a few thing differently, inflated my tires to max sidewall rating (44 PSI), coasting more often especially when red light were approaching, etc. My mileage went to 35. I was pretty happy. I kept reading. I finally decided to drive a little slower, I was driving 75-80 mph in my commute. I lowered that to 55-65. My mileage for my last 2 tanks are 42.1, and 43.0 MPG. Its possible to get great mileage out of these cars if you change your driving behaviour a little.
#180 of 195 Re: Nissan Altima Owners: MPG-Real World Numbers [KarenS] by texmiguel Jul 26, 2008 (1:50 pm)
Replying to: KarenS (Jun 14, 2005 5:48 am) 08 Altima 2.5 w/CVT   These past six months my mileage has improved slightly, after a front wheel alignment and breaking in the motor. On the open highway in Texas I drive 400 miles between towns often. I donot fillup till I arrive at my destination. At first I got 33 mpg more or less depending if I use the AC. Now I get an avg of 38 per the car's trip computer if I donot use the AC. This driving 65-75 with very little traffic or towns in between. I am very happy w/mileage, but I do not track use intown as of yet.
