I have read in past threads that some 6th gens have MPG reading of 24 mpg efficiency. I don't know if there is something wrong with my console or car, but I have never had better gas milage better than 19.8mpg whether city or highway driving.
Is this normal? please help

 

some drive way slower than others lol..

 

Stupid question: are you resetting the fuel mileage when you fill the tank each time?

 

yes, but i'm talking about the fuel economy button on the center console

 

Are you sure you are resetting the computer and not just displaying the mileage? The next time you are on the highway, press and hold the FUEL ECON button for a few seconds. Hold the button until the mileage appears as *.*. Then give the car a minute or so to calculate and display it’s new average mile per gallon. The number displayed will change every minute or so and reflect your car’s average mile per gallon from the time you last reset the computer. If you are on the highway and it remains at 19.8 mpg, there is something wrong with your car.

 

After I reset it fluxuates alot, but always ends up around 24Mpg for me.

 

You need to do a manual calculation to determine if your Max's computer is accurate. I followed both readings for about a year and found than my computer is very close (on average) to the results doing a manual calculation. I've come to believe that my computer is actually more accurate than the manual calculation -- because it is impossible to fill a 20 gallon tank to the exact same level each time you fill it up. If you fill to a lower point, the calculated mileage will be higher than it really is. If you fill to a higher point, it will be worse than actual.

Check out your readings by doing the calculations to see if they are accurate. And be certain to reset the mpg by pushing the button as discussed above.

 

i get 18.5, but ofcourse i havent reset since i got the car, need to try that out today. the previous owner used to get 16mpg!

 

I always reset the "fuel economy" button everytime I fill up, and I always get b/w 29 - 30mpg (I drive 90% highway btw). Even when I do a manual calculation, I still get about the same figures. Maybe because I don't rev it up to 4K rpm as often as I would want to...

 

30 mgp!? i thought the max this car gets is 26? how slow do u drive dude?

 

I'll sure be interested to know how someone can get 30mpg out of the max too.

I get around 25 mpg on freeway, cruising around 80 mph, with smooth acceleration - not much sudden burst of speed or down shift.

Regarding manual calculation, what I do is reset trip as well as fuel economy meters after fill up. Check during next fill up how many gallon I have to refill and how many miles travelled, compare that to the computer figure.

Repeated this for as long as I owned my Max. Conclusion is the computer fuel economy reading is pretty close to my manual calculation. + or - 0.50 mpg

 

Forgot to mention I average 22.8 to 23.6 city and freeway combined. On rainy season the fuel economy suffers, average down to low 21's.

 

i get about high 19 to about 22ish and i drive both city and highway

 

80mph on a 55mph speed limit, thanks to my radar detector...

 

...on the other hand, if I drive mostly city, the best I got was b/w 25 - 26 mpg.

 

My average for a very long time was 18.2

Now its thankfully upto 20 flat actually. It fluctuates around 20 sometimes but mostly get 20 now, depending on freeway or highway driving. Also I always fill with Premium.

 

I've gotten 32mpg on hwy (100 miles), not slow. The gas needle barely went below full.

 

I get 21-24mpg city, 32.3 highway miles. Now that does happen most often when my trip is 2 1/2 hours or longer. City is a variable though.

 

19 MPG going 120........ highway

 

not a stupid question Dtinva:-))

 

My car is about 7 weeks old, and it's maintaining a 19.3 avg, however I haven't reset the computer yet.

 

i guess that answers my question, no i have not reset the computer ever since i got the car. thanks for the advice.

 

reset the reader on my car on the way home from work, jumped from 18.5 to 23.9! thanks guys

(makes me feel much better knowing that im getting close to 24 mpg instead of 18, although my wallet doesnt see the difference )

 

I get around 28mpg when I'm cruisin at 80mph. this is with some traffic here and there on the way. when im driving in city streets though i get around 18 which is horrible. this car is not meant to be driven slow =)

 

i have an early 2004 se...kept track of fuel economy manually for two years...average 21 miles per gallon for all types of driving on 89 octane...when compared to computer manual number was within +/- 1 mile

 

I averagen 22-24 I am always on the rug in traffic and on the highway i have got 27 running 90 from Ny back here to Maine. I dbl check with math, and my computer is usually pretty close

 

Hmm... a few folks are getting over 30MPG doing 80mph on freeways. I always drive about 80 on freeways but never seen my MPG go that high... wonder what's the difference?

My max is 2005 SE, spoiler + mud flaps, with everything else factory standard. I use premium gas. What about you?

Also, have you guys mod your max?

I'm really curious.

 

did you reset the reader when you filled up?

 

Um, mods? What are those?

That's right, a list of 'wants but don't have yets'....

Maxima.org decal rear window....
new air filter......
lip spoiler......
premium fuel...

Yeah, double checked, no mods here...YET!!!!

 

lol wtf? lost Swee?

 

I just purchased an '07 SE with the CVT trans. Immediately after picking the car up, I took it straight onto the highway for a trip out of town. The mileage was a very dissapointing 24.8 all highway. My combined mileage is currently at 15.8 with a very light foot.

What's with the 21/28 figures they advertise? I really like the look of the new maxima with it's larger rear spoiler and bigger tailpipes.

 

Once the car is broken in, the MPG will increase. The 1/4 mile time too...

 

mine is always at 19.9

 

Of course. Fill up in gas station close to freeway exit. Reset trip and fuel economy meter. Get on to freeway, drive for at least half an hour at steady 80MPH, the best I've seen is no higher than 25MPG.

 

When was the last time you reset it?

 

Just for reference, I have an '06 6sp with 3,900 miles on it. I did what you said a week ago. Filled up next to the freeway, reset the MPG on the display, and drove 220 miles at an average of 75-90 mph, but cruise set on 80 MPH for most of the trip.

When I got home, I had 25.4 MPG as an average.

 

In the city I get 12-16mpg (90% of my driving). Best I got was 30.5mpg, no A/C 65mph on cruise (Lowered car and CAI probably helped). Highway I get 27-28mpg while driving above posted limits. And yes, I do reset each time and match with manual calculations.

Tire pressure may be a factor for some.

 

the car gets horrible mileage on stop n go traffic, like someone posted before, this car just begs to be driven fast...and who am i to disagree? STEP ON IT!
