Replying to: omelet1978 (Dec 23, 2007 11:24 am) 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 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!?

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.

Yeah, it seem to be improving. My last fill-up was 19.9mpg, so hopefully it keeps going up. I'm expecting just over 21mpg when it is all said and done since i'm using regular. Typically, when I fill up it's anywhere from 15-17 gallons btw. Oh, and 15mpg is pretty low, I would take it to the dealership and have them look at it.

Hi all, I recently put on snow tires and my MPG went down from 32 to 26. What would that mean? My MPG is  Track Your MPG
