A more analytical MPG thread please.
why the freak would i lie about something so stupid.
and i dont have one of those cool trip things like the newer cars, mine is analog. i have to do math when i calculate mpg. either way, that was a few years back when i was n/a, id be lucky to break 25 now, my last trip was 22 mpg all highway.
The same reason why people lie about how fast their cars are...
All i am trying to say is that some people here think their cars are as good as hybrids when it comes to MPG....

As soon as his SES came on with two EVAP things and two others I can't remember, the ECM kindly dialed back his efficiency so he now can't exceed 24 MPG, even driving the same as when he'd hit 32 with him an' 3 fatties in the car.
This. And no, I didn't use my trip computer...It gives me crazy high estimates all the time.
Not sure what I'd get at 60-65 on a long road trip, speed limits out here range from 70 to 80 and so I'm usually going 4-5 over-except where it is 80 because they enforce that pretty tightly.

Sound like your rely on the trip computer and subtract 3 mpg, and drive too fast to get decent mileage.
Oh well.

not so good
What MPG did your vehicle get on the most recent tank of gas? 18.5
What percentage city/highway driving did you drive on your last tank of gas please?30/70
What is the year, make, & model of your vehicle?
02
Do you have the 3.0 or the 3.5 liter engine? 3.5
What type of gasoline did you use, if you know what octane you used, please specify, or if you do not know, please specify regular, mid grade, or super.
93
How many miles are on your vehicle?123k
Do you have an automatic or a manual transmission? auto
Is your vehicle modified for the purpose of improving performance or for the purpose of improving MPG? both, k&n intake
Does your vehicle have any mechanical problems, please briefly explain if so? bad breaks
Do you rely on exclusively on your trip computer for your MPG information? no i do it my fill up and do the math
Do you use the following method to calculate your MPG;? yes
1. Reset (one of) your trip odometers to zero at the same time you fill your tank completely full.
2. At the next fill-up, fill your tank completely full again and then divide the number of miles by the number of gallons.

No, I don't rely on the trip computer, I actually divide the gallons into the miles but from experience I know the trip computer is 3-4 mpg too high so I can make an educated guess as to what my actual mpg is.
And seriously, if you want good mileage, a Maxima is not the car to get. Get a Sentra instead.

Just Calculated...
My last tank of gas I went ahead and did the real math (divided miles driven by gallons to fill the tank). It came out to 16 mpg! That seems pretty bad, although my driving during the week is 99% surface streets, stop and go, lights, etc... On the weekends I drive more on the highway and so I get a little bit of good mileage, but 16mpg seems pretty awful.
The car runs fine though so I don't know? Is it my lead foot?

It's a well known fact that the trip computers on the 5.5 gens are not accurate. They read between 3-5 mpg's higher than reality. Calculating the mpg's yourself would result in a more accurate and realistic calculation.

Agreed. Our cars aren't going to get good mileage in heavy stop and go traffic and winter gas and cold weather makes it worse. Only averaged 25 mpg (real mpg, not trip computer) on my trip to Kentucky and back for Thanksgiving. My moving average according to my nav was just over 70 mph so it wasn't like I was hauling ***** there and back.

I love the power this car has (hence my 16mpg!) and I really enjoy the "cruiser" aspect of the car. On road trips is where this car really shines - smooth, powerful and full of bells and whistles. I enjoy my heated steering wheel very much on our cold winter mornings, it gets so hot that I can't even hold it sometimes.
My previous car was an '02 Explorer, so awful gas mileage is nothing new to me. Of course now I'm buying premium fuel...
I'm no expert but I have done a small test goin at different speeds on the highway and I think that fuel economy depends more on how you drive than how far and fast. It seems that your act rpm has more to do with your fuel economy that your avg speed. Apparently the lower your rpm is, the less fuel you consume, therefore to maintain optimum fuel economy one must maintain the lowest rpm possible for the desired speed. For maximum fuel economy you are going to want to keep the lowest rpm after final gear, that speed should be your mpg sweet spot; mine is about 52 mph @1900rmp where I averaged 27.4 mpg. If you keep your rpm close to or below 2k you should deft see an improvement in fuel economy, however I must point out driving that softly and slow isn't very fun.
On the way to Kentucky and back though, 25 was about it and at lower speeds.
