Gas mileage...

[locski]

per tank?

My MPG is pretty crappy.  240 before the the gas light comes on!

Thanks.

29.5 miles to the gallon, ~380 miles between fillups.

Check your air and fuel filters, spark plugs, and O2 sensor.

Wow, 29.5 mpg is really good.

My best was 28.6mpg a couple weeks ago and last night was 27.5mpg.  I have no idea what I got the weekend at the track but at track touring in third gear at 40-55mph I could watch the needle drop over the half hour.

Basically it ends up being 100 miles per quarter tank so I usually fill up at a quarter tank left at 300 miles or so.  Light comes on around 325-350miles.

Wow you guys get great mileage... I dunno what it is about the SF Bay Area (we get ripped off for gas prices, maybe we also get crummier gas too?) &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/mad.gif" border="0" valign="absmiddle" alt=':angry:'>

My city average is only about 20 mpg (if I'm lucky) but when I drove down to the convention I got 32 mpg down to LA and back (if I did my math correctly). I was driving really fast as well... averaged 90 mph on the way down and 75 mph on the way back. I would check my usual things, but I honestly have no explanation for this... any ideas?

I bought mine last august and i was getting 25 easily. now all of a sudden it's dropped to 18 and 19 consistently. i have new O2 sensor, plugs, wires, fuel filter, and K&N cone filter. maybe my cat's going.

[sporty240]

btw when i'm doing some street racing banging through gears, i get 6 mpg for the whole tank. i've done it about 4 tanks now, so i know it's not faulty math. &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hehe.gif" border="0" valign="absmiddle" alt=':hehe:'>

20mpg.. un-tuned stock '89 KA24E with a leaky injector seal, fist sized hole in the exhaust, and exhaust manifold held on with 4 of 8 bolts.. &nbsp;On a trip from San Jose to Napa, I saw 26mpg.

[srJOEYdet]

I got 28 mpg going from denver to pdx, about 75 mph the whole way... Than i was getting 15 froma bad 02 sensor, and american plugs ( in the whole time!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> Definately look at the plugs wgen you buy a car. Autolife plugs are shit! I got NGK V powers.

Are you sure they aren't autolite? &nbsp;If they are autolife, I really have to wonder how someone couldn't have a buck twentyfive per spark plug that they went with the "cheap" imitation brand. &nbsp; &nbsp; &nbsp; &nbsp; <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hehe.gif" border="0" valign="absmiddle" alt=':hehe:'>

[srJOEYdet]

Yeah. They are autolite...

My average at 29.5 may go down a bit, 'cause I moved in town and nolonger have the 80 mile a day commute. ftr, my best mileage that I tracked was about 31 mpg :-) Car runs on 87 octane Chevron, and i've only seen my fuel light twice.

[DuffMan]

27 in mixed driving. It seems to stay at 27 no matter how hard or how much stop and go I drive it.

[240 2NR]

Mine was the same way, no matter how I drove (unless I was unusually lead footed) was always 28mpg, be it highways at 80mph or mixed use. &nbsp;Pure city, track days, and winter, are about the only times it's substantially off.

S14 SR, i get just ups of 20mpg. I also street race a lot. Its good to mess with civics.....eheheheheh <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I was doing an experiment, FUEL Tank is suppose to be 17.2 gallons in s14's.

i go to E mark in about 12-13 gallons of usage. I let it run down after building up courage. Right now my fuel needle is 1/4 tank much below the E and the light just came on 5 miles ago today while driving to work. Any of you guys have this much gap or is my fuel needle way off.

BTW, i will put gas today while going home. I don't think i will run out, Supposedly one still have like a gallon or so in tank when light first comes on, or so i "heard".

If i don't rape all the time at lights and daily driving, or when i go to school to a nearby city, i get good mileage, like ups of 25mpg. One time i had to go highway for over a week and my mileage for that tank was about 31mpg. I was impressed. I was running at stock 8psi/sometimes at high of 15psi during this reading.

Generally the idea of the low fuel light is to give you fair warning. &nbsp;My S13 generally has 3-4 gallons left after first coming on. &nbsp;

A while ago we sat in traffic in my parents accord for an hour with the light on and still had over 3 gallons left by the time we got gas. &nbsp;So your situation is not uncommon.

[BEISSEN]

i only get about 250 and if i wait till i am empty all the way dry i get 270 to the tanl so what can i check to get that corrected and i have no gas light
