help today i filled up and i have 158miles and i filled up 9.4 gallons...i did the math out and i got 16mpg these are all city miles!!! not good....what could it be?? for the most part i keep the fan on 2, i warm my car up for like 5-10 min (remote start), i don't usally floor it, but it happens sometimes umm other than that i didn't really do anything else to the car....ohh ya i use 93 octane and i always try to fill up at 1/2 tank.

 

you might wanna try replacing the fuel filter and maybe get the fuel injection cleaning done on ur car.

 

you shouldnt let your car ilde for 5 mins!! 10 to 40 seconds then drive.

 

btw it could be your knock and 02 sensos

 

Yea i noticed the same thing... just let it warm up like one minute instead of 5-10 that eats up a lotta gas...

 

also its winter time so the gas is a different kind (oxygenated) so it will burn noticably worse in all cars. i am around the same milage, as well i had the same milage last year during the winter but during the summer i was around 20 mpg. Im gona try to replace my knock sensor eventually and see if that makes any difference but i dont really expect it to.

 

I just replaced mt ks and I saw no difference in gas mileage. The performance is much better though. Im averaging about 17mpg

 

i was doing 18.8 mpg, changed the fuel filter and got 18.4. this sucks, but its worth it to drive a maxima

 

damn, im in the same boat. i got around 90,000 and on a full tank i barely get 280 miles. i was getting almost 300 miles earlier this year. car seems to idle a little harder than before too. the only good thing is, the car accelerates much faster. could it be the engine is eating up more gas to give me more power? and why would it be doing this all of a sudden?

also, isnt it better to warm up the car for a couple of minutes or until idle hits around 1000 rpm so the engine will run smoother?

 

In winter the intake sucks in colder air which results in more power. A lot of people have different opinons on warming your car.

 

In regards to warming up the car during winter, do what you normally do. If you've been idling your car for years without problem, than stick with it. I let my car warm up a bit before I move my car.

 

Not to hi-jack the thread but a quick question from a newb...does the GXE call for 93 also, I'm guessing it does being it's the same motor but I'm not sure.

 

How many of you getting under 20mpg are manuals? That is pretty lousy mileage. I average 23-25mpg in the city and close to 30-31mpg all highway.

Do you all use regular grade gas or the "recommended" premium?

 

u r lucky ... that's it

 

I consistently get 27mpg in my '95 SE 5spd. I got 30mpg on one trip were I had to keep it down around 55-60mph. Glad I didn't buy an automatic! Still, less than 20mpg seems really bad; are you guys gunning it at every stoplight and expressway on-ramp? Driving style can have a lot to do with fuel economy. Just a thought.

i seem to get 26ish using premium 93 octane from sunoco

 

Check your tire pressure. . . underinflated tires give less mpg.

 

How many miles on the car? http://forums.maxima.org/showpost.ph...6&postcount=39

 

80,000miles ish

 

oh **** not another gas mileage thread....

take into account alot of things that affect gas mileage... tire pressure, recent tune up, winter gas, gas filter, alignment.. etc.

I'm lucky if I get 14mpg city... but I have a bad 02 which isnt really bad... but for some reason my ECU thinks it is and its triggering my knock sensor giving me sh!tty gas mileage

 

I have no input on mileage, but I want to note that I hate you bastards who can get 93 octane... stupid California.

 

i just saw how far i could go on a full tank and i drove about 315 miles before the light came on. Thats good right ?
