I know maxima's aren't great with gas mileage in general but DAMMM!! i be spendin lotta $$$ on gas, even just drivin on da highway...

Here's what i got, 98 gxe, 73k, 17 konig imagines with 235/45 R17s rims... changed my spark plugs about a month ago, new air filter... haven't changed out fuel filter yet, but going to soon...

Here's the thing, i'm only gettin about 300 miles to the tank.... from what i remember our tanks are about 14-16 gallons... that equates to roughly 20mpg... dat sucks for highway... doesn't it???

what are u guys getting?

are my wheels causing bad gas mileage? what yall think?

no one really have a substantial answer to problems of hight gas consumption alot of people say check tire pressure , air fileter, fuel filter , tb stuff like that I personaly done all of this changed KS , also did seafoam last week the performance of the engine increased but the gas consumption stayed the same. this weekend im goin to check the resistance of the injectors and coil packs althou i get no engine codes there is nothing more i can think of that might couse bad mpg o btw i get 15-16 mpg city and its not stop and go traffic

our tank is 18.5 gallons, and your not figuring your gas consumption correctly...since this was talked about literally a day ago, you can read back on it.

Depends on a few things other than maintenace(sp), like hard acceleration, hard breaking, wheel weight, system in the trunk, and if you take lots of short trips.

I get 425 miles per tank on 80% highway 20% local. I wish can get more as per drive 100 daily. Fuel economy is the main problem with owning a Maxima.

22 mpg in Los Angeles traffic. That is pretty good if you ask me. For a nice sized 4 door sedan with high performance engine I am more than happy with 22 mpg.

Gotta say I easily hit 400 miles on a full tank of gas every single time I fill up. That's getting caught in Atlanta traffic almost daily. I hit 500 per tank when I drove to Atlanta from Buffalo - all highway driving at around 85 MPH average. I don't THINK I drive like a granny - shift at around 3300-3500 every time.

Well i'm a little below the half tank mark and I've gotten about 200miles so far.

I don' see myself gettin much more than 300 miles this tank... But if some of you guys are gettin 400+, that's insane... There's gotta be something really wrong here...

I dunno. When my gas needle hits the first 1/4, I'm always over 100 miles on the tank. At the 1/2 point, I'm always over 200. When it reaches the last 1/4, I'm around 340-350 miles. I hit 400 and the orange fuel light hasn't come on at all.

Highway driving, I'm over 100 miles and the needle doesn't even look like it's below F.

You guys that get low gas mileage, do you warm up your car for a few minutes everyday?

when it's cold out and i'm in a rush to get home/whatever... i usually don't warm it up like i should...

hoping to put in a remote start in few weeks that would really help with this. good stuff tho... i'm gonna pay attention to see what i get when i get to 1/4 tank... dont think i'll see 400 tho.

My lastest tank was 413 miles on 14.96 gal. Alot of highway, but some of it at 90-100mph. Avg on this tank was still 27.6 mpg. Keep your car tuned and get good mileage

I used to get 400 miles to the tank, but since about a month ago for some reason I can only get about 250-275 on 16.5 gal with mostly city miles and I always run 93. I don't know what's up...

I usualy get about 320 a tank if I drive like an *******, 430 if I baby it. One thing I don't get is I've only seen my low fuel light once in 2 1/2 years of owning the car. I fear running out of gas cause sometimes that needle is way down there yet still not light. Anyone else have this prob?

City miles and autos tranny's don't mix. The max is rated at 21 mpg in the city with the auto. If you drive the auto hard, i would think the mileage is much worse on a auto in the city than the manual max. My 5 speed has a much lower gear so the car uses less gas getting up to speed than the auto. Thoughts??
