I got 27.6 MPG at 75 mph last week on the highway on cruise control, and this week, with short trips in the city, I get 13 MPG. 13.8 with super slow acceleration tonight.

What the hell? Why am I doing 13.8 city and almost 28 HW?
34 000 miles, new air filter.

I mean, it's 15-30 fahrenheit outside, and I was in some traffic, but still.

Alignment was just done, its dead on. Tires are properly inflated.

What MPG do you get with your 6th gen 5 speed auto? What could explain good HW mileage and poor city? Dirty injectors? Should I run some injector cleaner in the gas tank?


Thx

 

It's the stop and go flow of traffic you get with city driving as opposed to highway where it's steady for the most part (not accounting for rush hour traffic of course).

 

because that's how cars work. mostly coasting vs. braking and re-accelerating.

 

pretty much the same here... and i got 103k on a 04 se with an ingen intake

 

So how come it's advertised at 12L/100km and I get 17-18?

Do you guys put some injector cleaner fluid in the gas sometimes? I remember that it really helped my 92 tercel. Could it help low speed fuel spray pattern and increase MPG?

 

Wow...

 

if your car did not come with all the manuals, they are available online. so many of your questions are explained in them.

 

Combined (City/Hwy) mileage of about 21 MPG, I'd call that good.

 

I agree,
Kryogen, I'll bet you caught several red lights? that will make your mpg drop like a lead balloon

 

i have 04 stick and i get right 16.2mpg. it used to be 13.8-14.6mpg. its normal dude. dont hesitate cuz thats what i did too.

 

Boats use a lot of gas.

 

Kryogen - I am getting about the same.

When you think about it, it makes sense. We waste gas by being in lower gears (using more RPMs to cover less distance) and stopping and starting at lights and stop signs much of the time while we are doing city/suburban driving, but stay mostly in high gear and do very little starting and stopping on the highway.

The EPA's 'city' MPG estimate has always been notoriously high for true city driving. It more closely replicates suburban driving with just a little city driving.

Of course, if you are going by the onboard computer's MPG display, don't even look at it while accellerating, even if doing it gently, as that always sucks gas in any situation in any car. Look at it while moving along, neither while accellerating nor while coasting. Both those situation give extreme numbers, not indicative of overall MPG.

 

You would cry if you had my gas milage with all the mods I have. I am lucky if I get 20mpg on the HW. I don't even pay attention anymore, just fill it up and drive.

 

What to you get on your rowboat?

 

lol. yeah same here

 

My mods actually improved my mileage, something is wrong w/ your cars.

 

First fill up was 18mpg FTL. Supercharger drag = less milage. I'm not whining about it though.

 

i had a 97 with cai /ypipe/exhaust/and 18" rims--always got 11-14 miles local and a few trips to NC i got 430-465 miles to the tank

 

Laughed my *** off when I read this. It took 2 hours to wax my boat today lol

On topic:
I get about 17 city / 25 hwy

 

I say Wow Wow -

 

lol.. 08 maxima _ 16.3 - 17 mpg.. thats what the freakin trip thingy always say.. i do combined highway and city driving though so i duno.. i fill up $50 super/premium every 4 or 5 days =/ ... v6 baby!!! bought 12-24-07 brand new.. now i got 3,500 miles .. in 2 months!!

 

yesterday the car read 16.4

 

You are bad brotha

LOL!!!

 

Ok I got 28.5mpg last trip on the highway, which is really good, and

11.7 mpg city. Ok, there has to be something wrong. I'm SUUuuuper slow on the gas, I dont WOT, and I'm not stock into major traffic.... I mean, why am I not getting 15-16 MPG?

What could be wrong? Air filter is new. no CEL.

 

ure cars SCREWEDDD!! lol jk... dude dont go by what the moniter tells u... do the calculations yourself... maybe the screen is fukin with u lol

 

Why not go by what the screeen says? Can the screen be innacurate?

 

Dear lord for the love of god!

 

9.5 MPG now lol... thats ridiculous.

 

how high you rev in city driving? man b happy ab8 what you get hear in ny i never go over 2.5k and i still get 11 or 12mpg. and hwy i dont even know i dont get to go on hwy its just school then home and maxima.org. lol mine is 2k i30 tho not 6th gen

 

Yeah you must be doin 80 everywhere you go!!

Drive it like you stole it huh!? lol

 

No, mostly traffic driving for 1 mile, then engine off. Cold temps, and snow on the roads....

So maybe it just reads alot from idling all the time....

 

Dude - if you're are really getting this mileage there is something very wrong with your car......
How many tanks of gas has it been since you reset you mpg screen?

 

Are you going by the car's computer, or are you calculating this MPG yourself?

 

probably 30 miles. I reset it after a long trip to see what my mpg is in city.

So thats for the last week of city driving. Car computer reading.

Still, I think thats alot, even in city driving.... aint it?

 

Try calculating it yourself, the computer is not always right.

 

the dash says i am getting an average of 26 mpg. I drive mostly highway. on weekends when i'm not commuting it goes down to 22. i have gotten as high as 29 on the highway and as low as 10 in the city. there is nothing wrong with you car

 

Yeah.......
