We purchased the vehicle back on September 8 of 2007, drove it about 500
miles and then started keeping track of the mileage even though we do
not drive it very much. As we live in a VERY rural area of Iowa almost
all of the miles are highway miles. No "stop 'n go" miles here because
our county does not even have a stoplight! :-)
Like all of the vehicles that we have had that had an mpg display this
one also displays a bit more than you actually get in reality. Anyway,
if you are interested take a look and of course your comments are welcome.
....and yes, I know that it is cross posted.

That seems about right. It appears that the vehicle calculates mpg
rather accurately; I think +/- 2 or 3% is doing pretty well.

Do you know the algorithm that the computer uses to track mileage? Is
it tracking cumulative mileage since the last reset, or does it use a
moving window (mileage since last reset or for last "x" number of
miles, whichever is less)?
What impressed me most was how consistent your averages are. It works
out to something like 21.75 +/- 1.35 mpg. I have never been able to
achieve that level of consistency with any of my vehicles.

Ed,
From observation it certainly does not seem like any fancy algorithm,
just a simple average being cumulative starting and ending with the reset.
The consistency comes from a repetitive and boring driving schedule to
and from the same destination all in rare decent weather. In the winter
we normally drive one of our pickups which have all wheel or 2 wheel/4
wheel drive rather than the Maxima. Now later this week I will be
driving the Maxima about 800 - 1,000 miles on basically Interstate so we
will see what that does to the mileage. One would think that it would
increase the mileage as it is basically a "straight through" shot but on
the other hand, it could lower the mileage due to the higher speed.
Well, that was more than you wanted to know. :-)

Interesting mileage figures and considering you say it's mostly highway
miles I consider it's MPG low.
My well worn older tech 3.3L Chrysler Concorde from the mid 90s is
quite a bit better on the highway. I keep track of all my mileage &
fuel.
