I just picked up my Mo on Saturday and have noticed that the on board computer says I average 12.5 mpg. I am still on my first tank of gas that came with the car. Is it normal for the car to be that low in the begining or should I be looking into this? I do 1/2 city 1/2 hwy driving.
:confused:

There's quite a few threads on this -- I should know, one of them was my thread complaining about the same thing. :)

Do a search, or start HERE and HERE and HERE and HERE .... there are more, but you get the idea.

Ella,

Your car is new and the engine is not broken in yet. Reset the trip computer and try again after a few thousand miles. Your MPG may be somewhat higher with premium gas. Check highway driving and city driving separately to get a better idea.

How do you do that?

My 05 has about 1000 km on it with even highway / city driving. The fuel ecomony registered at 18 mpg. I don't recall what it was when we picked it up.

If you press and hold the button, it will reset it and then it starts all over in it's calculation. You know it's reset, as the numbers are replaced with ***

The other problem with the vehicle, is it's too much fun to drive. Unless you're very light on the accelerator, it will suck more fuel. I think about what entertainment costs, like taking the family to a movie, or going out for an evening. Then I think about how much joy the Murano is to drive. It helps offset the price of gas in my mind. I wouldn't pay less and have to drive something that's not as much fun...

Definately, it should get better as the engine is broken in.

Here's my first 4,500 miles and as you can see, it gets better. These are all actual mileage calculations based on the manual method, not the computer's guess-estimate. Mine had 91 miles on the odometer when I picked it up. The last coumn is the octane I put in for that particular tank.

OK we have 3400 miles now so I feel I can chime in here...

We have consistently gotten 20.x mpg in our MO S. I wonder if its because its the lighter S or just FWD.

On the highway at 75 facing the wind we got 19.x, with the wind we got 24.x But, I realized that we had the 50PSI problem, and havent retested highway since.

We dont drive with a lead foot (at least not this car) but we dont granny it...

I put in Synthetic oil earlier this week and hope for a bit better.

BTW< and yall may not like this, but we run 87 octane.
