I dont know what seems to be the problem but I have the 02 GLE max and i clocked the mileage with the trip meter MANY times and the most mpg i end up getting is 15 and i usually get about 240-250 miles per tank. I DO NOT UNDERSTAND THIS. Ive had it looked at my mechanic, compression, he used those machines(excuse me im a noob) checked for leaks, signs of tuneup, plugs, like WHAT THE **** IS GOING ON!!! lol please help any feedback wud be GREATLY appreciated

 

Stop doing burn outs at every stop light.

 

i DEFINITELY do not do that

 

how do you drive it, and what type of gas u put in it? i have a 03 and i put premium BP and the worst i got, it was the first week i got the car, was 19mpg that was becaus i used to burn out on every stop sign. now i get 22.4 avg

 

do you drive fast in general? I do and I get some poor *** gas mileage. Now I drive about 65 in a 55, cruise on and get decent mileage

 

I drive a lot of short trips, I mean really short trips and drive pretty fast on the highway, but I don't think I've managed less than 18 MPG. I thought I was getting crappy gas mileage, I guess it's not as bad as I thought.

did you try any of the suggestions given to you in the newbie thread? doubt it, so here are my suggestions:

go to autozone, check for codes
check fuel injectors
check fuel lines for leaks
replace all o2 sensors
replace/clean air filter
replace pcv valve
change driving habits
use 87 octane
regret buying a car you can't afford to drive
get rid of car
deal with it

 

I thought changing the pcv was only for emissions purposes...

 

damn you get less mpg than my toyota. lol good luck with your gas bill :X

 

even if I go to redline through every gear on my 02 I couldn't get 15 mpg. Would use up a whole lot of oil though...

 

Gotta love the laziness of this country!!......lol



Anyways, I suggest doing some research, first...cause honestly, it could be one of several different issues...

Including, the PCV valve, o2 sensor (s), MAF (mass air flow), Clogged injectors, Bad gas, Dirty air-filter, ect ect...


Also, I was told (atleast here in Ohio), that the change-over from "summer" gas to "winter gas" is about a 20-30 mile difference (winter gas -20-30 MPG loss), as the chemical compounds that are used are different from that of which are used, during the summer.......

Personally, I would run 93 octane (or 91, whatever's available to you) to see if that helps any, and then go from there!

If that doesnt fix it (after a couple of tanks), then I suggest trying one of the other ideas we gave to you...



Process of elimination, man!



GL!

 

this car's a 3.5L it's a pretty big engine so just deal with it lol i've been averaging between 15-17mpg and i've learned to just deal with it. when i first got the car it was a pain in the wallet but it's worth it for me cuz i love the torque on this car compared to my previous car (2000 accord v6 coupe) haha but i don't know how people get their mpg's in the 20's but i best i've ever got was 19 and that was one time and i was so excited lol

 

Good lord, then I'd get -3 MPG if I took a hit tha big

 

Hahaha....oops


I mean per TANK!



lol, thanks Nmex

 

I knew what you meant.

 

Wrong. I've been horrible lately and my car sees reline at least 5 or 6 times a day with constant 5 minute trips and I still get 19 mpg (lowest ever). It has nothing to do with the displacement.

 

there is no way you should only be getting 15 mpg...i would have to say something is clogged...my 2k3 is getting about 25 mpg with it being winter and thats me redlining about 3 times a day...and 21 is the lowest ive ever seen...then it comes back up

 

I suggest checking your tire pressure. Since it's been extra cold lately your tire pressure may be too low. If it is that low, then you'll probably gain about 2-3 mpg (my estimation)

 

When did you notice the change?

 

lol maybe nyc gas sucks. im getting about 180miles to a tank and im not even redline or anything. just some speeding and short local drives to and from work. still doesnt make sense for 150-180 to a tank lol

 

idk how ur pockets handle that ,..150/16 gallons = 9.3 mpg ,... thats serious,.. big rig tractor trailors can even pull like 5-6 mpg lol

 

Yeah, this has happened to me and I figured out it was someone who did not want to buy their own gasoline.

 

I put 93 Octaine (the best ****). I drive it a little hard sometimes, for instance on highways im usually doing between 60 and 80 MPH, and thats about it. Im getting about 15MPG. I dont understand. I sometimes press the gas a little more than neccessary but not that much, otherwise im driving normal or a little fast and on highways most of the time i speed unless theres traffic meaning im going anywhere between 60 and 80 MPH..

 

obviously not, i do hardly any short trips and im usually doing above the speed limit, and its about 25 degrees here and freezing so maybe thats the reason, im NOT SURE??

 

FIRST OFF SMARTASS, if YOU wouldve read i said my mechanic did ALL THAT, and i CAN afford to drive it its just not normal for this type of mileage, OR IS IT? obviously not..

 

my mechanic checked the sensors and their fine, and my air filter is cleeean, and he also checked for leaks and all that said everything was fine he cant find anything wrong. any hidden suggestions even a mechanic wouldnt normally find?

 

no im trying to deal with it buddy but me and u r on the same page, ur just indenial that theres something hiddenly wrong for your mileage.

 

and me and you have the same car, could that be it that the gas SUCKS, or could it be the DRASTIC change in weather? what it is i have NO clue, if anything was clogged my mechanic said he wouldve known cuz he did all these ridiculous tests, and he said something about checked the smoke coming out the muffler that if any gas was getting lost it would come out the muffler or SOMETHING, i just know he knows what hes talking about. any other things u think?

 

tire pressure is fine, only problem is my front tires are different from the rear tires, the fronts have a max psi of 44 and the backs are max 38psi i believe so i have all 4 to 36 psi, could that be it?

 

actually its weird because i just bought the car about 40 days ago and when i first got it i wasnt complaining i didnt really realize then the longer i had it and the colder it got i tracked the mileage and thats what i got.

 

buy it from a dealer? if so bring it back and haunt them... you might have gotten a good deal for a reason heh.. g/l either way

 

dont feel bad, my gas mileage here in cali is not that far off. i had CEL(two months) and then it went off. gas milage was good, drove it normal for about two weeks. now as of last weekend CEL is back on, cant stretch the gears 1st-3rd, rpms are high but the torque is not there. mind you with the first CEL, the car was pulling hard. i just purchased a ODB2 scanner, just waiting to see what it says.

As a matter of fact i think the dealer where i bought this car turned off that CEL light before the car was sold (AS IS).seven days into the breaking in getting to kknow you period, the CEL stopped by to say ( hello I'm here too). go figure.

 

I used to live in Brooklyn so I know the kind of driving you have to do there. In any case, the weather's gotten colder, if you're warming up the car before driving, that will drop your mpg more than you know especially because the engine runs rich when it's cold, if you're running the defroster, that will kick on the a/c compressor, so there's many factors that could be the issue rather than something really being wrong with the car.

 

I was getting 17mpg and when I changed the spark plugs, it was 19mpg. Its currently 18.7 b/c I have been having fun lately while driving =P. Plus, I have a 6 speed and manual transmissions are known to be more fuel efficient compared to automatics.

Try changing your spark plugs if you have not already done so. You will be surprised at the jump in mpg

 

Did he tell you he did, or did he actually DO it?

 

same here i get about the same maybe 180 to the tank in the city (Brooklyn/ Queens) and long Island

 

im from ct and its been pretty cold here lately. i noticed my fuel miliage go down when its cold out. about 18-19. when its warmer out i get about 22. ALWAYS 93

 

So how is it working out for you?

 

A 2002 Maxima fuel tank holds 18.5 gallons. Lets say that you put 15 gallons in on a filllup. That works out to:

180 miles /15 gallons = 12 mpg.

A better way to calculate mpg is to fill tank and reset the trip meter.

At you next fillup do the same calculation as above, but use the following data:

Trip meter miles / gallons pumped to refill your tank = mpg.

That way you'll truly know your mpg.

 

How many miles? Clogged catalytic converter/exhaust? Dragging brake rotor? Excess weight (like storing your golf clubs in the trunk)? Engine temperature is normal (proper coolant level)?

Proper engine oil level? I ran into this on my gle, make _SURE_ you're not low on oil. My mileage started going off, and I discovered that the engine was down over 2 quarts....very scary as I'd only owned the car for 3K miles...filled up the engine oil and mileage returned. Moral of the story, check your oil often - like every 1K!!!

Oh and you need to sacrifice a Honda every now and then to appease the Nissan God's...
