wow really? never knew that a maxima's gas tank was 18.5 gal... are your serious? of course i know how many gallons it takes.. so why are you pointing that out? so when i fill up and look at the pump and see that i put 17.2 gals in my tank that leaves 1.3 that was left in my tank previously.. and if i have driven 526 miles on those 17.2 gals of gas well then what do you get as my mpg?.. how is this a fancy story? how are there wrong calculations in that process? i never said that the vehicle has a 16, or 17.2 gallon tank. not sure your point. i have stock oem se wheels otherwise i would have stated differently when i said that "i have a CAI and underdrive pulley.. those are the only mods that would directly affect mpg" ... oh and i run on 87 octane. EPA averages are just that... averages and estimates. it says on the EPA info that each vehicle must be dealt with by a case to case basis and that your results will vary. so if it has an EPA of 27-28 highway.. how would 30mpg be such a stretch?

i love it how everyone in this forum just tries to find fault in others statements. i know what i am doing and thought i would share based on the topic of this thread. your post adds nothing to this thread except to show your inability to read what others write properly, or do simple math.

My '98 GLE, when I purchased it in 1998, was getting up to 34mpg on the highway using 89 octane. Well above the 29mpg highway that was advertised on the sticker. Most recently, I am getting 30.3mpg highway using 93 octane. So, while I am happy getting what I am getting, I am getting a little less while using more expensive fuel. And, yes, it is 12 years and 213k miles later. Over the past few months, I have been much better at performing maintenance on the car, since the economy is forcing me into keeping the car beyond what I would otherwise do. It's not quite as good as it used to be, but the driver isn't either.

 

I get 35Mpg on the Hwy and about 24 City. Maxima only has 85K on it with a Auto. Mods: Injen CAI, Generic Knock-off of the Megan Racing catback.

 

I have a 1996 SE. I usually get 26mpg in mixed driving using 93 octane.

 

'98 GLE '28 Highway

 

140,000 miles
'98 max, I get 24 mpg city and stuck in traffic most of the time.

 

Full 3.5 swap with 4AT
Premium Fuel
Never worse than 26MPG all city
As good as 31.8MPG
Averages 28-29MPG
Best range I achieved was a full 520 miles on a tank
I "unleash the beast" several times a week, not a granny driver!

One time I had a dead O2 sensor, could only get 14MPG. Fixed that right away!

 

99 SE Automatic , 21.5 Hwy - 377 miles on a tank.

 

My 98 get around 21mpg. I drive pretty fast on the freeways tho. I have an injen intake and it's a 5 spd. I use premium.

 

95 GXE 200k miles get about 18-22 mpg up to 25 for long highway trips. No mods yet.

 

I'm totally stock, and getting 20.7 MPG and I drive 80% highway / 20% city... this is the average of several $20 gas purchases. (which averaged out to 7.301 gallons @ $2.737 per gallon)...

I know a tune up would help get me up to 24 MPG, but my driving style probably won't let me get that much.

 

i get about 20-21 mpg mixed highway/city on my '95 with >110k miles.

 

95 maxima with 155k highway 20-23 city 16-18 if im not beating on it

 

25-27 mixed - stock 96 SE 5-speed - 152K - 87 octane - Norcal

 

99 I30 103k miles. ~22 in the winter (mainly because I crank it to warm-up and go back in the house to fix coffee), ~26 in the summer doing mainly 80/20 city/highway.

Real world just now I'm showing 371.5 miles since the last fill-up...I'm almost on E but the light's not on yet. i'll fill-up again tomorrow & see.

not too bad...a heck of a lot better than my 425hp 06 Trailblazer SS!!!

 

Hi, still new here. Have an 02 SE with 125K.

I dont keep track of the miles when I put in gas, but the digits on the dashboard show 24.9 MPG. I drive about 75% on chicago's interstate highways.

Is that an OK mileage?

 

I kept a spreadsheet of my mileage for years. It was always around 22 with about 50/50 highway/city; driving fairly aggresively.

Then last January it suddenly dropped to 17 mpg. That's a drop of about 80 miles per tank. No codes what so ever.

So far I've replaced the plugs, air filter, and fuel filter. Cleaned the MAF, EGR tube (PItA!)and replaced the 2 O2 sensors on the y-pipe. Then reset the ECU. No change at all.
I tried to listen and feel around for vacuum leaks but couldn't find any.

The only change in January was a new set of tires. But unless these tires weigh 5 times normal tires I can't see it making that much of a difference.

Anyone have any other suggestions?

 

Knock sensor maybe.
My 99 SE-L just went on a major trip. I got 24-25 miles against the wind 80mph and 26-27 mpg with the wind. 2800 miles.

 

99' se 5mt. 103k. Average 23-24 mpg with 75% highway driving. I cruise around 70-73 on the highway, but flog the car good around town.

 

im getting 12.5 mpg after mods

 

24/30

 

ok.. this thread is beginning to get pretty lame.. It's kinda like that Youngest person here with a Max thread...

 

27-28mpg mixed driving on 91 octane gas. 96 maxima se 5 spd 203800miles.

 

17 here. I usually drive 50 mph. auto tranny. and I jack rabbit. (don't take 43 minutes to get to the speed limit, but don't floor it to the speed limit.)

 

i get about 20 city and 27-28 highway
5spd manual 444,000 miles

 

Post sea foam and follow up maintenance.

12-17/28/30 (Assholery/City/Highway)

173,xxx miles, always 93 oct, now running mobil 1 synth 10w30, and changed to a Z32 Fuel Filter.

 

you also overheated the **** out of it witch probably didn't help the milage.

 

Im getting about 20-22 city and around 28-30 hwy. Before I replaced my O2 sensor i was getting 17mpg hwy and about the same for city. Im sure if I stayed at 100km/h on the hmy I would get about 32mpg. This car has great mpg for the power and age.

 

I'll throw in my .02
19.2mpg
326 per tank. Intake filter (stock mid), pre cat exhaust leak, 28psi on tires, 87 oct. 80-90% highway and hardly any WOT shifts.

 

96 maxima SE with M/T
189,000mi
20-24mpg
constant 1320 code
safely 350 mi to the tank, but not much more.
maybe more like 320 if it is all city stop/go driving

 

97 maxima with swapped 5spd, 189,000mi
roughly 22-23MPG

No codes

 

Yo, you live in my town. I never seen your car around before.

 

Last fill up was with 89 grade:

268.1 miles - 11.3 gallons - 23.72 MPG

Driving is a mix of mountain roads + town / small city driving.

No mods at all, Blown struts & 15in wheels

Mighty fine if I do say so.

 

98 se no codes w/ 90k miles 5 speed. mixed city/highway =330ish to tank. Filled up with 93, paid $45 bucks to fill up...can't recall how many gallons.

 

Now I'm at 20.5mpg with 37psi for tire pressure. Same driving style, 87 octane from the same shell gas station. That is a pretty big difference and air is free

 

97 Max GLE
Auto
Replaced all belts, new air filter, cleaned IACV and TB, all tires filled

In a 200 mile trip up to new hampshire I acheived 37 mpg going 60 cruise the whole time.

 

'95 SE Auto

I haven't had mine in the summer, but in the winter running 93 octane and 4 studded snows, I'm seeing 20-21 MPG with my lead foot.

I drive 60-70 miles per day, and around 50 miles of this is 45 - 50 MPH rural driving up and down hills. The rest is stop and go city stuff.

...oh, and it's bone stock. CEL came on for EGR flow, but went off after a couple hundred miles and hasn't been back...so that might be impacting it a bit too.

 

stock 97 gle 122,000miles auto
using regular gas, 21 city 26 highway, and i drive easy 98% of the time

 

25-28 mpg

Knock sensor and post catalytic O2 sensor codes on, car has 325K+ miles with premium gas in it. Don't know how much longer I'll be using premium at the current gas price rates
