I own a 2000 5sp maxima and have been getting 17-18mpg. I was wondering if this was lower than normal and if it is what should I do about it. I do almost city driving but it stell seems low.

 

make sure your tire pressure is correct; also do the typical maintainence stuff (i.e. oil & oil filter, air filter, PCV, etc.). Gas mileage around the city really does depend upon your driving style. The more stop and go you're in, the worse off your gas mileage.

 

well i have a 2002 6spd and honestly i can get anywere from 12 miles per gallon to 32, really depends on how you drive. with a max you can keep the engin below 2500 rpm and still keep up with everyone, gets me about 28 mpg. or you can keep it around 4000-5000rpm and go as fast as everyone, just get to that speed a hell of a lot faster, at about 12-14 miles per gallon

 

I just changed the oil filter, oil, and air filter. I usually shift at 3k thought any lower would just bog the engine down and get worst mpg. But shifting around 2.5 will make it better?

 

i heard that before too. couldnt hurt to try it though.

 

With such a high powered motor, 18-19 is not bad. We use 87 octane to save dinero.

 

So it's not my lead foot then? I try to drive "normally" but i have do a nice pull to 60 once a day.

Wife has a 2K SE with 98K on the odometer, she drives 45 miles to work one way. I showed her how to keep the revs under 3K. She has for over two years remained at 28mpg. I check mileage every week, she writes gallons and miles driven at each fill up.

 

You will get less mpg by using fuel that has a lower than recommended octane rating.

Most of that stuff is is for the 3.5 i have the 3.0 engine. Is 17-18 bad for city driving? I would say 90% of my shifts are at 3k. I'm using 93 octane by the way.

 

Change your plugs and filters. If you still get poor gas mileage it could be the injectors. Try running a can of injector cleaner with your next tank of gas as well. I get about 18-20 mph in the winter shifting around 3-4K rpms about 75% of the time using 87 octane. I just got the car so im still trying to figure out the true mpg.

 

i get 19 on average and i have a auto 2000 GXE so id so ur doing fine but manual u should be getting better gas mileage then me right

 

I have an 02 6 speed... I could red line it on every take off and not get 12 mpg, maybe 17.5. I also shift between 1500 and 2000 when driving normally (90% of the time, city). and I get 20-22 depending how many stop lights I hit. Actually... I don't think my car has ever seen 28... even on all highway trips. Maybe 25.

 

03 Auto - 76K Miles - I Drive 95% Highway, burn 91 or 93, and if I'm really good I can squeek out 20-21mpg, but average 19-20mpg. A properly tuned manual should do slightly better.

 

Depending on how heavy your foot is, 18-19 for all city driving sounds right. I get around 22 mpg, 80 miles a day, over half is highway, where I drive over 80 when traffic allows.

No one ever seems to listen to me, but check your oil level. Most people (actually most oil-change places) tend to overfill, which causes decreased performance and efficiency.

 

Well I Have A 2003 Gle And I Drive Pretty Hard I Get About 17-20 Miles Per Gallon On Mixed Driving

 

i have a 2001 SE and i am always always on the gas... and i always get 30ish mpg.. doesnt matter if im in city or highway.. always thought it was weird but im not gonna complain...

all those articles say basically the same thing...

 

that was my point...all the info is out there (in MANY places)

 

I've been averaging right at 22.7 mpg per tank. My commute is about 50% highway and 50% city. The last couple weeks though I have been taking a different route that has a slower speed limit and my milage was 24.3 mpg the last tank. I noticed very little difference going from 87 oct to premium...actually I probably got worse gas milage on the premium since I subconsiously thought it was improving my performance and thus gave it a bit more gas.

 

I get around 18-19 in the city.
Low 20's on the highway.

 

It seems like I'm getting some of the best avg mpg at 28-29 on my 03 GLE.
I drive 30 miles city + 50 miles highway every day, M-F.
The digital display give about a .2 - .4 mpg *bonus* from what i calculate when i fill up.

 

 

for the 6mt...my tricks: shift at as low of rpm as possible, skip shift...and roll, roll, roll. last year Car and Driver did some testing on a 6-speed 3-series and made these same suggestions.

as long as you keep the rpm above 1000-1500rpm, the VQ isnt going to bog while just cruising. of course, when you need to accel, you have to down shift. now if we were talking about a 4cyl, the typical recommendation is to keep it above 1800-2000rpm while cruising.

when city driving i usually skip 2nd and 4th, esp. if i feel like revving 1st gear up to 3 or 4k. i learned this from driving GM 6-speeds that actually force you do do this under certain conditions (1-4 skip actually).

and finally, a big advantage of manual is to be able to put it in neutral to take advantage of the momentum from your acceleration departing the last stop light.

i average 24.5 with mostly stop and go city freeway driving. 28 on rural highway trips @ 80-85mph.

 

Yeah those F-bodies and the skip shift...

 

i'll pay the extra for gas instead of driving my 255hp 6-speed like a grandma (shifting at low RPMs, etc)

if i was worried about bad mileage, i would have bought something else. when i need gas, i get it. i dont b1tch...i dont drive around for miles to find gas thats .05 cheaper. i get gas, get in my car, drive away, and enjoy my car.

 

lol i second that

people that drive 5 more miles to save .03 cents/gallon =

 

Luckily it is very easy to defeat.....because my F-body is the car I drive hard; and the funny thing is that I still get only 2-3 less MPG than the Max.

 

Winter sucks...period. I get around 23mpg in the summer as opposed to about 19 in the winter. I guess thats what happens when the temperature is so cold.

 

I have an '03 GLE with a hellava lot of miles and I consistently get over 26 calculated mpg in mixed driving (70% hwy) in the warmer months and about 24mpg in the colder months. I've had as high as 30mpg on a long trip. I usually keep the rpm's below 3k with the occasional 'drive it like you stole it' run.

 

well how have you been counting your mileage because the gauge isnt always right, besides they have this new siite that actually re test all the gas mileage going all the way back to 1985. its called fuelecomomy.gov and you can plug in what you really get for gas mileage

 

You can't expect anything better than 20mpg around town. You should see around 28 mpg on the highway. Anything less and there is something wrong - anything more and you're lucky.

 

For those who done have to get there first:

With a manual transmission, shift gears as soon as the engine can run smoothly in the next gear. Low gear at 20 mph gives only about two-thirds the mileage as high gear at the same speed. In second gear, it is four-fifths the mileage you'd get in high.

With an automatic transmission, lifting your foot slightly off the accelerator will make the transmission shift sooner.

When approaching hills, don't wait until the car begins to "lug" before shifting gears. Don't accelerate once you have started up the hill, because speed increase is slight and fuel consumption is high. You can minimize the speed loss by gradually increasing speed as you approach a hill.

Cruise control can gain 1-2 mpg by maintaining a steady, preset speed over any kind of terrain.

Again if you're not in any hurry to get where you're going, get comfortable, find some good music, get in the rightmost lane and slow down a bit. You'll save 2 mpg or more if you drive 65 mph rather than 75. I find it'd a much more relaxing trip when I'm not constantly trying to pass other cars. Just make sure you're the one in the slow lane.

Also, if you want some better mileage, get rid of some of that junk in the trunk. and run the lightest wheels and tires that work for you.

 

been getting poor milage my self, 16-17mpg all city driving. time for me to change the plugs and fuel filter. how important is to flush the coolant?

 

Yes I realize the guage is not correct. It consistently reads 4-5mpg higher than my calculated mileage - which I actually calculate using the number of miles traveled and number of gallons used. I am just easy on the gas pedal most of the time, coast as much as possible, and do not let my car idle for very long in the morning.

 

yo i also have a 2k max 5spd.

could be alot of things--anywhere from how you drive to the gas youre using to mechanical probs. but sounds like you dont really rip up yo car, so its prolly not the way you drive...

like last year, my mileage started gettin real low too--like in that 17-18 mpg range. then my car started stalling randomly sometimes when the engine was returning to idle from a higher rpm (like above 2k). turned out to be my maf. changed it and got back up to like 21-22ish.

ive also noticed an increase in mileage when i use bp 93 octane vs qt or shell. i think the additives they add to the gas really help mileage. i also read a study where adding like 3 oz of acetone to 10 gallons of gas can help increase mileage too:
http://www.pureenergysystems.com/new...00069_Acetone/
i tried this before, and it seemed like my car got better mileage if i remember right. most ppl say at minimum, they get better response...(that could translate to being lighter on the pedal and saving some gas...)

i also seafoamed my car last week for the first time just to try it, but im not really sure if i notice any difference other than normal fluctuations...prolly wont do that again for a couple years...

right now im gettin about 24-25 mpg driving normally (faster than traffic, though) in half city/half highway. haha but try easin up on that pedal...remember, you barely have to give it any gas to accelerate quicker than most ppl.

the main thing is just to make sure yo engine is running smoothly and maintain it well. that should keep it powerful and efficient...

 

I have a 2000 SE AUTO with 160 000 km or around 100 000 miles

I've done the following within the past 6 months
Regular Oil Change at 5000 km or 3100 miles
Fuel Injector Service
Flushed Transmission Fluid
New Bosch Platinum Plugs
New Air Filter

I drive roughly 40km/25miles on hwy at 120 km/h avg or 75mph and 10km/6miles city per trip.

Temperature varies from -25C/-4F to about 5C/41F and I have new winter tires on with 32-35 psi always

If I drive normally ie. regular acceleration (shifts at ~2500-2800rpm) i only get 15L/100km or 15.68MPG and if I drive as slow as possible (shifts below 2000rpm) the best I ve got so far is 12.5L/100km or 18.81MPG

When I drove last time from Toronto (where I live) to Detroit with 5 people, I've got 580km per tank at 125km/78mph cruising 100% of time.

Is this normal?
