Whats your gas milage? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

XxDriverxX · 03-24-2002, 09:02 PM

I get only about 15 miles per gallon. Msn Carpoint says I should be getting atleast 21mpg. That means I'm loosing atleast 6 miles for every galon! What could be the problem?

http://carpoint.msn.com/Vip/Engines/...240SX/1992.asp

I know I gotta get my fuel filter changed, and that my engine is old (130,000miles). Is there anything else I'm missing out on?

Thanks

tnord · 03-24-2002, 09:04 PM

should get about 24 city and 30 highway, at least that's what i get when i'm not tearin around

adey · 03-24-2002, 09:30 PM

I would tell you what kind of gas mileage I'm getting, but can't because my friggin' odometer's broken.  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/huh.gif" border="0" valign="absmiddle" alt=':huh:'>  I can tell you though, that it isn't good. I smell gasoline in the exhaust fumes.

Not like this helped any, just letting you know you're not the only one getting shit mileage.  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

Red · 03-24-2002, 09:38 PM

Well that sucks, But the good news is that mine was at the same thing, But I took it in and got my O2 sensors cleand and it helped out quite a bit.. I still get crap tho (lead Foot Syndrome)

I was geting 13 per gallon, <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/nervous.gif" border="0" valign="absmiddle" alt=':nervous:'> (lead foot)
I now get 15 per gallon,  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/lookaround.gif" border="0" valign="absmiddle" alt=':look:'> (lead foot)

If I drive like a normal person its about 19 per gallon.  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wow.gif" border="0" valign="absmiddle" alt=':0'>
I hope this helps.

27mpg with mostly highway driving. 187,000 mile SOHC, no leaky injector here.
try fuel injector cleaner.

*LanceS13* · 03-25-2002, 12:56 AM

I get 27mpg usually.  If nothing anybody's suggested works, just get your foot out of it.  I checked mine at my last track day and it deteriorated to 9.7mpg.   <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wow.gif" border="0" valign="absmiddle" alt=':0'>

Alias · 03-25-2002, 01:00 AM

17.3 Driving like I'm nuts. WHich I do all the time. I don't think I've had a tank that I've drove nice on. I will soon though as I break in my clutch.

Takumi · 03-25-2002, 01:57 AM

Well, I only drive 10 minutes tops per day cuz I just drive to the BART station (it's a train, Bay Area Rail Transit, or something) to go to school on San Francisco.  Trust me, half hour train ride and a couple blocks up from the station is way better than sitting an hour in gridlock, then driving around in a crowded city like SF to find parking, then pay for it.  I thought I'd bring that up as a side note in case some folks are wondering why I don't drive to school instead. Hehehe.

Anyway, doing that everyday, I get like, I dunno, 13 or so miles per gallon and my broke ass teggy's supposed to get, what?  22 city? *shrug* I guess I'll replace the fuel filter and pour in some fuel injector cleaner.  Then again, I drove around from place to place for an hour and half one day and the trip meter said 48 or 60 miles I forgot, when I got home and my tank was only a half to 3/4 inch empty. I guess it also matters where you drive too.  Cuz if you're driving in the highways a lot more than you do in the city streets, you'll get better gas mileage since you're not stopping and going all the time.

240meowth · 03-25-2002, 03:32 AM

i absolutely feel you, i'm gettng like 13mpg... i have a 93 coupe. but, just last week, i decided to figure out the problem, and drove VERY nicely, i got 250mi on the tank which is 17mpg... i really have no clue.  i'm gonna try repalcing these:

fuel filter
02 sensor
air filter

maybe in the next month or so

JpS · 03-25-2002, 06:23 PM

also try:

spark plugs and spark plug wires
changing your oil (helps more than you think)  mobil 1 5w-30 is good
make sure your tires arent under-inflated

oh and i get 24 city 33 highway...    <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hehe.gif" border="0" valign="absmiddle" alt=':hehe:'>

weitau · 03-25-2002, 11:39 PM

Castro makes great oil too.  Tested in a 1.6L 4 cylinder Mirage, and I got extra 2 mpg.

misnomer · 03-26-2002, 12:16 AM

33 MPG, beat that <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

'>

This was on a highway trip from Vegas to Tucson. Changed oil, oil filter, spark plugs and wires just before leaving. Changed air filter the oil change before that.

I averaged 27 on my commute before this work, I'll recalculate it afterwards. Granted, my drive is predominantly highway miles, though I still can't fathom how you can get 13 MPG in an s13 <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

*sykikchimp* · 03-26-2002, 03:06 PM

Here is your list of things to check/change (good stuff to do just as a basic tune-up)

Spark plugs/Wires (got me an extra 2mpg)
Oil (I think for your app 5w-30 is a little lite.  I would use at least 10w-30 b/c of the miles on your engine)
Distributor/rotor cap
Fuel filter (get a 300zx TT filter)
O2 sensor
Air filter
and dump in a Bottle of Fuel injector cleaner

If that doesn't help,
Clean out you Throttle Body, and make sure your MAF isn't dirty.  If these were part of the problem there would be other symptoms such as odd idling problems, etc..

Also make sure you don't have any wetness around your injectors.  Not generally a problem on the 91-up 240's but you never know.

240sxracer · 03-26-2002, 04:23 PM

21-22mpg mixed driving. best was 32mpg on a trip to austin.

*sykikchimp* · 03-26-2002, 10:05 PM

this type of topic should be in the FAQ.  (hint, hint, Mark...)

Tearlessj · 01-10-2008, 02:21 PM

I know this thread is OLLDDDD.

But I recently just started paying for my own gas and I have noticed that im getting terrible gas milage. I recently went on a 200 mile drive, all highway. I left with a full tank and got back with a little bit over E when I got back.

Sometimes I have to give it a little gas when I start my car. Even after driving it all day. Would this have anything to do with it? Maybe a loose vacum line somewhere? Where should I start?

SR20n00b · 01-10-2008, 02:22 PM

sr20det redtop. 20mpg city.

Quail · 01-10-2008, 02:28 PM

OEM SR20DET - just under 20mpg mixed driving. Fuel is around £1.10/liter atm over here

i need tires · 01-10-2008, 02:32 PM

30 highway... like 27 street when driving nice stock SR.

lovely240 · 01-10-2008, 02:37 PM

i dont know, i just know i fill the thing up like once a week and it lasts me all week...and i drive everyday half an hour to and from work....I used to have a 97 nissan sentra and i went to vegas, I filled the tank up and made it to vegas it was a 330mile ride...sweet mileage...for real

hustlervibes · 01-10-2008, 02:50 PM

Stock KA with highway and street. Last tank I got 26 mpg, need to change my oil too.

Rob's S14 · 01-10-2008, 03:56 PM

I get between 25 and 30, it just depends if I do alot of highway driving or not. If I drive conservatively I can easily get 400 miles on a tank, a little more aggressive gets me down to 360-375.

bziggers13 · 01-10-2008, 04:33 PM

23 around town..28 hwy. pretty decent for a 15yr old motor!

drifter808 · 01-10-2008, 04:40 PM

i used to get like 30mpg but just recently its been getting worse. like 20mpg and under worse.

Andrew Bohan · 01-10-2008, 04:43 PM

48mpg mix of street and freeway, with occasional full throttle bursts to 120+

deng! brought the thread back from the dead with vengeance.

1995 240k miles..... i used to get 25/34 on base wheels and suspension but now on 17" wheels and coilovers i get around 23/30

***FaLKoN240*** · 01-10-2008, 06:01 PM

I was like, WHO THE HELL BROUGHT THIS BACK?!

I got 16 mpg recently, then I said "FUCK THAT" cleaned my air intake filter (AMSOIL) and sprayed some throttle body cleaner into the intake manifold. I am getting about 20 mpg now I think.

Stock KA with intake and exhaust.
