Okay,

All you 2k2 owners out there, whats the best average fuel economy you've achieved according to your ICY?

I'm on my second tank of gas with my 2k2 6 spd and my average right now is 8.2 l/100km, which is approximately 28.7 mpg. Hopefully will go up as I break it in....

 

how did u get 28 mpg????
my 2k2 has 400 miles on it now, and the mpg dropped to 17.1 mpg from 22.5 when there was only 1000 miles on it

 

Well, hopefully I didn't goof on the conversion. I went to this site: http://www.pege.org/fuel/convert.htm and they have a nifty little converter. It seems about right though.

To answer your question, since I'm breaking her in I generally drive it like a little girl. Easy on the gas, shift at around 2500 to 3000 rpm, make use of 6th gear as much as possible. Even when I'm tooling around at 70 - 80 km/h I keep it in 6th.

Also, my commute to work is about 25 minutes, half of which I spend cruising at 120 km/h and the other half I cruise at 100 km/h. At these speeds, the engine is turning at 2200 rpm and 1800 rpm respectively. Its practically idiling.

I don't sit in traffic, I don't do alot of city driving, I run the climate control in Econ mode 99% of the time.

It doesn't seem that far out of whack with the mileage my wife gets on her 2k 5 spd. When I was driving it, I was generally getting between 550 to 600 km per tank, and it takes something like 55 to 56 litres to fill up, which puts it in the 26 mpg range.

Ironically, I think the 2k2 can get better mileage because of the extra gear despite the bigger motor. 120 km/h in our 2K Max corresponds to 3000 rpm in 5th. 120 km/h in our 2k2 Max corresponds to 2200 rpm in 6th. Same way a Corvette gets like 26 mpg on the highway despite having a 5.7L engine.

21.8 mpg/avg...and not driving like a little girl either!

 

avg 24.0 with 3700 mi

 

That's great mileage. Mine actually went up about 1 mpg when I installed my Stillen Intake.

 

obvious my mpg is the worse, i don't do alot of hard driving.
i tried 1 tank with easy driving & 1 tank with hard driving, and the results came out to be about the same 17.5 mpg.
do you guys think there is anything wrong with the car(note: the car is NEW, only 2 months old)
I notice the dropping in MPG right after I got my first oil change ( 22.5mpg-17.5mpg)
HELP PLEASE

 

You guys are not usuing you computer EMG read out's right? My computers off exactly 4 MPG, always. I calculated at the pump a few times and my best MPG to date was 21.9. My worst was 19.8 MPG. I hardly ever drive on the highway so this is to be expected. My 95 maxima averaged about 1-2 MPG more.

 

ya i don't use the computer, i calculate it myself!!
i think more than half of my driving is on highway! so i really don't under why my mpg is dropping like that

 

2k2 SE,auto, about 2k miles. Best mileage to date has been 20.8 mpg

Live about 26 miles from work, but unfortunately a lot of it is gas-stop-gas-stop-GAS-STTTTTTOOOOOOPPPPPPP!!!!

 

2K Auto Max with 25K miles gets 23.2 MPG driving across country at 90+ MPH. In town 17MPG, caluclated from pump #'s.

 

I am on about my 4th tank of gas and my average is 20.5 mpg. It's 20 miles to work and it's mixed driving.

 

I can't believe you guys are getting mileage like that. I have a 2K Automagic with 68K and I get 26.5 to 29 mpg. I drive city / highway mix and NOT like a little girl. I can really tell a difference if I do a lot of city driving with my foot in it all the time v/s all highway driving. I run premium and throw in a bottle of injector cleaner every 5k or so and keep the tire pressure at 33 psi (17" 225/50's) gotta check the tires often - especially in the cold months.

 

What size gallon is everyone using to convert? It's typical for Americans to convert to US gal, whereas Canadians normally convert to Imperial gallons.

I've got a spreadsheet at http://www.cenpipe.com/~akrusvar/Maxima/maxtracking.xls with my first 18 fill ups. I've got calculations for L/100 km, m/US gal, m/Imp. gal as well as my fuel cost/km.

You can definitely see when I'm on the highway doing about 130 km/h. My everyday driving is about 30 km at ~90 - 100 km/h with only about 4 stops each way. I do let my car warm up a couple of minutes, so I'm waiting for the breakin and spring weather to coincide and I expect at least another 5 m/Imp gal.

All in all, I'm very impressed by the mileage of the car. BTW, I've got a 2k2 6spd.

22.1 MPG

15 minute drive to and from work. 1367 miles with alot of driving around. Slowly getting better too. I started out at 15 mpg when I first drove it off the lot.

 

 

damn i'm gettin' really worry, I'm the only one who's mpg is 17.
I'm gonna bring it to Nissan next week hopefully, I'll let y'all know wassup!

 

You're not the only one . . . I also have been getting about 17MPG (U.S. gallons). At 80 MPH in 6th on the highway I've seen it go as high a about 23 mpg, but in local driving with short distances, I am getting well under 20 mpg. I would point out that now that the 1000 mile break in is done, I have not been "babying the car". I do try to shift by 3k, for better fuel economy, but I do periodically go to 6k just for fun . . .

I'm also located in the NE and have read that the fuel mix is changed for the winter and that this can cause worse fuel economy compared to fuel in southern parts of the country.

 

With about 1500 miles now, I'm averaging 21.3 mpg. My trip computer is telling me 25.3 mpg. It's typically off by 3 mpg around town and off by 5 when mostly on the highway.

2002 6-spd grey/black

 

All this poor gas mileage.. My 99 gets 28 on the highway at 80 MPH on a long trip. Around town it's about 23/24 mpg. And I'm a righty if ya know what I mean....

 

I am getting 27-29mpg. Currently getting 27mpg
and thats here in the good old NY winter weather.
I have the 2002 Max GLE auto with 2800 miles.
I have not gotten below 25mpg even since it was new. I drive 90% highway and use only 93 octane
gasoline

 

Just took a little trip yesterday and I reached new levels of fuel economy according to the trip computer.

Now I know the trip computer isn't terribly accurate, but its still fun to see how well you can do.

Anyhow, at one point I was down to 7.5 L//100 km (31 mpg) but after making the return trip I was down on my mileage, with the average at 7.8 l/100 km (30 mpg).

I filled up and reset the computer just before we left, so this is all highway cruising.

 

My mileage has dropped down around 24-25mpg.
I have calculated it myself as well as using
the computer.

 

Well here's my $0.02 driving a 2k2 auto.

Odometer: 1528 miles.
Average temperature: 50 deg. F ambient.
Tire pressure: 33 psi all round.
Gas: Amoco Premium in Illinois (which I believe forces some additives )

Highway fuel consumption:
20.7 mpg when driving mostly @ 80 mph.
24.34 mpg when driving mostly @ 65 mph.

All measurements made by getting gas at the same pump. Trip computer routinely shows more than these figures!

[Haven't carefully measured city-driving fuel consumption yet. That'll be the next project ]

 

I just kicked over 2000 miles on mine and I am averaging between 23 and 26 with normal city driving. This includes the daily highway on-ramp sprint or two that I must lay the pipe for....

I did make a long trip to PA during Christmas and the CPU said I was pulling 31.5 mpg for the duration I was crusing. I was doing about 82 in 6th and loving the mpg.

 

Has anyone lost gas mileage due to a high-flow intake installation? I would assume the ECU would calculate to use more fuel for the increased air flow. Of course, I may be wrong.

Going based on the trip comp. I get ~22.5MPG (1800 miles, US gallons, high test, California gas so it has additives, half traffic/half highway, heavy on the foot when I can be, 50 degrees F., close to sea level, winds 10MPH out of the west, etc.).

 

I took a short trip last week, about 200 miles round-trip. (still in break-in period, only about 600 miles at the time) According to the computer I was getting 32 mpg on the way there, did about 15 miles of city driving, and by the time I pulled into my driveway the computer said 30.5 mpg. I thought I had gotten an extra gift from this already terrific car; I could smoke a Mustang and get the gas mileage of a Escort. Then I filled up and calculated -- 26 mpg -- still not bad. I agree that the trip computer is about 4 mpg off. Maybe I should have driven until it was empty, but that is still a pretty big difference.

 

Over the weekend, I drove 2 hours to Richmond. I reset the trip computer in my driveway, and it took me about 20 minutes to get out of town (to the highways). By the time I reached Richmond, I was showing 31MPG. I was generally cruising 70-80 MPH, with more than a few full-throttle middle-lane passing maneuvers (one which resulted in a speeding ticket ). One the way back (reset again) I got 30MPG.

Travelling to Ohio in January, through the hills of Pennsylvania with a strong headwind, I got 27.5 (that was pretty consistent too).

Around town I've been getting 22-23. Again this is all per the trip computer. I've read some people saying that it's off by around 4MPG -- is that 4 over or 4 under? That's OK though, I like what it's showing me so I'll pretend it's accurate.

 

In my 2K1 I averaged around 23 mpg, but so far on only one tank in my 2K2 I did 25 mpg. My commute to work is 26 miles with 10 hwy/16 city.

 

HA u guys make me feel really bad!!! when i had my car (still in the shop by the way) i was gettin 15.2 mpg HA what can i say i love the sound of that intake!!!! hehe!!!

will

 

I dont know but i get 250 miles with a full tank of gas, i got a 2000
Roger

 

On a interstate trip currently and am showing 30.5, am guessing that is optimistic. My previos 97 Max would do 31 on the highway.

 

I'm the loser of the group. I average between 11 and 13 mpg around town and about 18mpg on the highway at anywhere from 90-140mph. However, the in-town milage consist of my street racing habits.

I have over 8500 miles on mine now and just last weekend on a trip, at mostly highways speeds (70sih) but it was up and down hills and around some twisty roads (gotta get sway bars) I averaged 20 mpg. The computer said around 23.5. as stated though that was doing some heavy footed drivingaround some twisty roads so a lot of brake and then heavy gas. Not bad I guess but I am still not used to not getting over 33 like I used to with my old econbox hyundai
Cheers

 

Awww, don't blame yourself. Look at my earlier post. Notice that most of the folks who get better mileage than us drive the 6sp. We pay for the magic in our automagic.

 

My 2K2 SE 6 spd readout says usually 28 mpg....since it is generally accepted the computer is "off 4 mpgs" then im ave 24 mpg with mixed driving. My SE has 1700 miles. JAKE02
