hey, how's everything? just bought a 3.5SE about three weeks ago and i'm almost hitting 1000 miles on it. my mileage really sucks though, it's like every time i get 200 something miles for a full tank. was your mileage this bad during the break-in period? what type of gas are you putting in your car? any advice would be appreciated by my wallet, thanks!

THE REAL NISSAN ALTIMA TRUTH by sellcar

I just traded in this "P.O.C." 07 Altima for a 08 Hyundai Sonada and its a so much better made car for less money then the 07 Altima. Check the reviews on yahoo autos and see for yourself' !!!!
As for the 2007 Nissan Altima 2.5 SL it owned, I had many problems with it that the company could not fix, from the brakes squeeling to the engine pinging and engine knocking noises when it was cold, interior plastic squeeks. The drivers seat tracks had to be replaced the first week I got the car because the seat was loose. The dealer scratched the interior up trying to get the seat out of the car in order to fix it. I checked the gas mileage many times by filling up the tank and resetting the trip mileage counter and best MPG's my car can get is between 19MPG to 23MPG city/highway and this is on the 4cyl. model. I even tryed using high test fuel and I got very little change in MPGs. I don't think the on board MPG trip computer is a good way to check the mileage. Nissan customer service sucks and they don't care about there customers after you buy there car, they told me to try another dealership after going to 4 different dealers who could not fix this cars problems. In the past, I always recommended Nissan cars to all my friends and family, but now I tell everyone to stay away from them. I hope yours turns out better then mine. Happy Holidays!

2008 Altima 3.5 SE by omelet1978

I drive ALOT, and I average about 1800 miles a month. I read up on premium vs regular and even found out the dealer puts 87 in, so I've just been using that and it has been running fine and has lots of power. I have filled it up and calculated the miles vs the fuel I put in the tank and came out with the following mpg: 18.8, 20.1, 19.5, 19.5, and 19.4.
 
I've read on here that the mileage will go up 2-3 thousand miles and that the computer adjusts to your driving habits. Is this true? I was hoping for an average of 22mpg per the new fuel economy standards. My previous vehicle was a Toyota 4Runner and the new fuel standards said it averaged 15mpg which was dead on.
 
Oh, and just out of curiosity, if I were to put in premium, would I make up the extra cost with better fuel economy?

I also experience great mileage. 2004 2.5L, gets average of 25 MPG in town and 32-37 on the highway, depending on speed. Recently drove across the state of Iowa, cruise on at around 68 MPH, and got 37-38 MPG. Going 70-75 MPH, I get a lower 32 MPG or so.
 
Had a 97 Altima, and loved it. Never tracked the milage that close, but it was great also. And this car had so much more power than a Honda Civic.
 
The 04 does make some engine noise, I wouldn't necessarily call it pinging, but I have ignored it and considered it semi-normal. Had a check engine light come on and the dealer lowered the idle RPM, which I think is now a bit low.

I take it PUG is the recommended grade. Your computer can and will adjust timing for the lower octane (87) . You do lose app 10% in performance, which on the face of it is really not a big deal. So what remains is really a cost benefit calculation/problem.
 
Do you pay less for regular and get slightly worse mileage or pay more for premium and get better mileage? TEST IT!
 
So for example using YOUR RUG mpg; your average is 19.46 mpg/rug price per gal= $? per mile driven. Just do 5 tankfuls of PUG and see what the mpg is and what the per mile driven is. Compare obviously. Then you can make a decision based on (objective, hopefully) comparative data.
 
Personally I would ask why would you buy a car that requires/recommended premium, when buying a vehicle that requires/recommended RUG would have done just fine? In all likely hood you would have paid FAR less. RUG costs less, and you could have used those saved monies for more RUG!?

Well I bought the 3.5 b/c I like having a powerful engine. Money is not tight for me, but I do have a house payment, a new car payment, insurance now on two vehicles, etc...so I feel like I'm throwing money away using premium. It's not that much, but I just don't think it is necessary. My previous vehicle, a V8 2004 4Runner, suggested premium as well, but when gas prices went up I put regular in and it worked fine as well.
 
The 3.5 is rated at 270hp, and 258 torque. 90% of that is 243hp & 232 torque which is still plenty of power. Thats a 68hp and a 52 torque difference, so it is still significant. Despite being a 4500 lb vehicle my 4runner was pretty fast, and using 87 the Altima is significantly faster.
 
Also, it's a Nissan Altima, not a BMW 3 Series. If I bought one of those I would use premium! I'm not insulting the Altima here by any means. I think it's a great car! Oh, and btw, filled up today and it averaged out to 19.9 mpg, so it seem like the car is slowly starting to get better mileage.

Oh, I was comparing the 3.5 to the 4 cylinder when I said 68hp and 52 torque difference.

hey omelet, just curious if your mileage got better with time? i'm still running about 15 mpg. If i'm not mistaken, the altima has a 20 gallon tank, which should last at least 340 miles if the mpg were around 17 and up. i have 700 miles to go to hit 2000 miles so hopefully this gets better as xmas shopping has me mad broke
