i just filled up and got to 288 miles and filled up 13 gallons flat 22.15 mpg, all city

 

i get these numbers through fully filling up my car. I get 280 miles per gallon tops, and i just got like 288 i think? so lets average 290.

not sure how many gallons our car holds, i thought 16 but someone told me 18.5?

if 16, i get 17.5 miles per gallon

if 18.5, i get 16.7? miles per gallon

either way something is wrong, very low numbers and this is though city driving and shifting at 3k rpm TOPS, very peaceful/careful driving....

 

ok mecca, if you ran ur car empty, you'd be pushing your car into the gas station, so that can't be right, next time when you fill up at 290 miles, check the pump to see how many gallons you filled and then post here with the # and then you can calculate it to the exact number, i 100% gaurantee you that your not filling 18.5 gallons or even 16 gallons each time

 

ok, exxon just robbed me, i filled up 15.6 gallons. I normally fill up between 14-16, never 18.

 

haha and how many miles was that at bro?

 

oh and mecca are u using 93 octane? or regular?

 

always 93 octane for MAXIMUM performance . I dont know how much miles i will get but i am at the second dash, the one after the Full line and i'm at 106 miles...i have been driving kind of hard though....

 

ok so next time u go to fill up take note of the miles and the amount of gallons! let us know what ya get

 

420.6 miles on 16.605 gallons of 93 = 25.29 MPG. that was with about 65% highway, 35% city.

 

Yeah i'm in NYC and our "city" driving is really really bad most of the time. even when there's "minimal" traffic, it's still a constant stop and go routine. I probably average anywhere between 230-270/full tank down to the fuel light. I almost never get the rpms past 3k, have 80k miles, and i use only Mobil's Super unleaded. any ideas how to raise my mpg?

 

dammit, had to put 5 dollars worth at 1.85 a gallon due to a long trip and didnt want to take a chance. I was at 283 miles with a lot of aggressive driving. when this 5 is almost done i'll let u know how many gallons i put when i refill, didnt check how much at 5 dollars .

 

I was finally able to calculate my MPG.

In dead set stop and go traffic, I'm so far getting about 18MPG I was hoping to get at least into the 20's especially now that I'm using 94 octane. Hopefully these numbers will increase gradually..

 

i get 22-25 mpg with a dead knock sensor.
and always get better then 350 per tank.

 

don't forget that proper tire air pressure affects you mpg too!!!!!!!

i get avg 19 mpg 50% mix city/hw
i won't say i have a lead foot but let's just say i pass people and don't often get passed.

 

the most i have gotten without the gas light is 470 miles and i get 25 in town and 30 mpg on the highway

 

My record is 29.7mpg... automatic 2000 Maxima ~33k miles, and a full-tank ride on I-80 west into PA. (which REALL REALLY surprised me, because the terrain is hilly, and I was cruising at ~80-90mph the entire way... very very very far from optimal!!!).

I still have the gas receipt and mileage since full somewhere to prove it!

PS. I usually average between 26 and 28 mpg highway.

 

How will higher octane (than the recommended 93) get you more MPG?


-Tom

 

OK, i'm ****ed...I told you guys, I have a '97 GLE with around 85k miles on it. I was getting around 210-240(when i'm lucky) miles per tank! I didn't do the exact measuring method which i'm gonan do next but i;m ****ed because I just got a tune-up about 3 weeks-1 month ago and I got a new air filter AND NGK Platinums put in. The car definitely felt a lot smoother but the mileage didn't get better one bit. I think i'm going to change my Knock Sensor, is this ok even if I don't have any Check Engine light coming on? I've bene reading around and some people say the new KS improved their mileage. I'm getting desperate, wasting so much money on gas, sdo you guys think it'll help?

 

buuump....

 

It blows my mind that some of ya'll get 500 mi! I've never gotten over 400. 320 is about average for me and thats after driving a good 30 mi with the light on.

 

Driving style has not changed one bit since I got the Max in June, and I've found every gas receipt since then (Don't drive much anyways), and I've also noted km's driven for each, and from my calculations, I've been getting increased MPG since my first tank, which makes me believe that I still have SOME room to go up..

 

320 for me too. I'm manual and I get 320 and lately I've pulled out 340 miles on my fill-ups because i'm more confident about how many gallons I have left cause I know how to calculate it. Which brings me to my next thought. I don't think everyone is calculating their mileage correctly. People keep asking about fuel tank capacity. I know it's 18.5 gallons for 97-99 and I just assumed it was for 95 and 96 too. But why do they keep asking for this value? They don't need it if they're calculating their mileage correctly. All they have to do is fill the car up, zero the trip odometer, drive for a little while or until they're too scared to drive any more without getting gas, go to the gas station, fill up again, note the gallons pumped to fill the tank again, note the miles travelled since last fill-up, divide that number by the number of gallons needed to fill up, and voila, you've got your gas mileage. So is everyone doing that?

 

i've been doggin the car almost the entire tank this time cuz i put in some chevron fi cleaner, and i stil got 20.59 mpg

 

Hmm... are you getting gas at the same station?


-Tom

 

Just thought of something obvious.... where do all of you guys getting 200-300 miles per tank live? (most importantly, altitude wise)

I live pretty close to sea level... and get between 26-29 mpg...


-Tom

 

ok, i just did the accurate measuring thing, with measuring the miles travelled and the gallons to fill-up, turns out I got 50.5 miles from 2.55 gallons. That comes out to around 19.8mpg. TO get my full tank estimate, would I multiply that by 16.5 or 18.5?

 

I used to get about 250 on a full tank, then I added some performance parts, let off the heavy foot a bit and now get about 280-300 by the time im down to 1/4 tank left. I still get on the gas every once in a while, doesn't seem to make a difference though.

 

what performance parts?

 

Fuel tank capacity is 18.5 gallons. I don't know where that number 16.5 came up. It's 18.5. In the 1997 maxima instruction manual I have, fuel capacity is on page 9-2. It's 18 1/2 gallons. Here's a link to the edmunds.com site with the specs on the 97 max: Nissan specs at edmunds.com. But for the sake of other people, and as zealotnyc showed, you don't really need the fuel tank capacity to see what kind of gas mileage you're getting. One thing though, zealot, unless you can drive the whole range of your driving style within 50.5 miles, you may want to go 2- or 300 miles to get a more accurate calculation.

 

i get 260-290 mpg on average, whether i drive conservative or beater-like. I live in Maplewood, NJ and i frequent newark everyday since i go to school there. I want to hit 300 mpg, dieing for it man!!! I kept receipt for last tank i filled, gonna fill up again and update u guys on what i got. Nismo, may need u to do calculations for me ol buddy ol pal

 

haha no problem, just make sure u have the number of miles and the gallons u filled up!

 

yeah, that's my next experiement to gauge my mileage...i'm taking a trip up to Syracuse this Thursday, i'll fill up sometime on the 90 and report my results

 

i'm gonna clean my throttle body before the trip tomorrow...first tiem opening up my car myelf, wish me luck! let me clear up one thing...after i disconnect the MAF and the air filter, when I spray the cleaner in teh tthrottle body, should the enging be on or not?

 

i just replaced my throddle body postioing sensor, and now my gas milage is insane. I got down from atlanta to vero beach flordia on a tank and a quarter, and that is like 550 likes.

 

what's a throttle body positioning sensor?? well, i jstu claned my TB for the first time...grimy as ****....idling nicely at between 650 and 700

 

This is something that I've wanted to do for a while but I'm chicken. How long does it take you? I see those cables and stuff and I'm wondering what happens if a spring or something pops out or something. I'd hate to screw up something. Is it hard to screw up? How involved is it? Are the instructions in Haynes detailed enough for what you will encounter?

 

I normally get close to 400 miles on each fillup. Today I drove my car until the idiot light came on (407 miles) and I filled up. I had to put 17.2 gallons in. I know the specs state that the 95-96 have a 18.5 gallon gas tank. I have a 5 speed and I do occasionally gun it. The only mod I have is a HKS intake and that improved my gas mileage. I have gone over 500 miles when I am on the highway if I use the cruise control and cruise no higher than 75 mph.

 

the thoroddle body sernsor is on the back of the throddle body. It is the little black thing, with 2 wire connected to it.

 

Minimal, trust me, it's simple and this is the first time i've done anything myself on my maxima besides changing the headlights and stuff like that.
I just printed out these directions here http://www.motorvate.ca/mvp.php/517
and got to work.

It was really easy, I have some helpful hints though, the air filter in the pic is diff. from stock, so if you have stock, you're gonan only end up taking off the top half of the air filter box thing. It's real easy to spot, it's held down by 3 or 4 clasps. And the thing the guy talks abotu disconnecting in the first step, its the little wire chip conncector thingy attached to the square black box.

To loosen the round metal bracelet type things on the hoses, use a plier type of wrench and squeeze the two ends together to get it to open up a bit, it's hard to do it with just hands.

Once you get everything off, the dirty part is actually inside the chamber area, so you need to push down the little lever next to the TB, that's the throttle, so the chamber opens up, spray inside and wipe down, repeatedly, and don't forget to wipe the opposite side of the butterfly plate, the side you can't see, i almost missed that part completely today. Go as deep as you can go with the rag.

once your done cleaning, put everything back in place, don't forget the little tiny black tube.

your car should be hard to start the first few tries, but it'll catch and then let it run for like 5 minutes, should be smooth as a baby.

i also noticed that my car seems to coast a lot better, like if i go 40mph, and let go of the pedal, the car will go a lot further withouth slowing down.

 

Preciate it man. I have a newfound boldness after reading your instructions. I'm going to try this probably Friday. I'll let you know how it turns out.
