S13 gas tank capacity

[asher4857]

Ok, im interested in how big the gas tank on the s13 is. It seems like im getting around 60 mpg/1/4 tank.. so im just trying to figure out my gas mile.. thanks guy

[sensibleS13driver]

IIRC the tank is 14 gallons, but if you really want to calculate your MPG fill your car up with gas all the way, reset the trip odometer, drive for 100-200 miles to get a good variety of highway and city, then fill it back up fully and divide the amount of miles driven by the amount of gas that was needed to fill it back up theres your miles per gallon

[Japanese Steel]

I think it'a 16 gal. tank.

[sensibleS13driver]

I think it'a 16 gal. tank.

you may be right I'm not too sure, but in either case i wouldnt beleive a S13 gas gauge to be accurate, i know mine goes up and down depending on how I am driving.

[Zydeco]

Yea, its 16 gal. and 60 miles per 1/4 tank is realy bad.

[asher4857]

anyway to improve it, or know of anything that could be wrong?

Do you have the SOHC? If so check to make sure your injector O-rings arent leaking.

[asher4857]

yes, i have an sohc, ill have to do most of this over the weekend with my friend since i know next to nothing about working on cars..

[Zydeco]

Start with a tune up, I just did one to mine and it only cost 160 bucks for, spark plugs, wires, car, rotor, O2 sencer, fule filter.

[Thee 240sx Owner]

I thought they were 11 gallon tanks... hmm... maybe the canadian models are different.. brb time to look it up

[InsanityInc]

Uh. Why would you go through all that math when you could just fill up with 10 gallons and run it back to where it was when you filled it up last time.

[lrb_2000]

s13 = 15.90 gals14 = 17.20 gal

[fatboy]

i know for sure my 89 got a tank 15 and 7/8 gallon tank.

[drifter_for_life06]

my 92 base model hasa 15.9 gallon capactity

[xekushnr]

15.9 is correct.

[drifter_for_life06]

tis the reason i posted

[Graphfixz]

mine fills up with 14 and that is with it being on the red for a long time and the light blinking.

[Bruno240]

mine is 11.9 gallons

[GripR]

i fill up when it's on E all the time and it usually is 13 or 14 gallons.

yeah that is the s13 gas gauge for you. i bet it still had ~50 miles on the tank if you had kept going.

yeah but you'll end up like that guy on the commercial, telling his wife there is a reserve tank...

[JimmyMethod]

I finally got to see my gas light!My S14 ran 390 miles, and it finally blinked on for a few seconds. I was really disappointed in my gas mileage this tank, which was 24.375...last tank was 32, but I drove fairly hard.But anyway, Project Nogas was a success. I was excited.And by what I can tell, the gas meters 'quarter tank' tick marks are really '1/5 tank' tick marks.

First basic thing you should check is your tire pressure. If your tires are low, your mileage will actually suffer greatly.

[asher4857]

my tires are fine..

[Florida240sx]

hmm thought it was 14.9 but guess I've been wrong all this time...

[hek1620]

just taking of the air box and adapting a cone (k&n or whatever) on the maf gave me a lot more mileage. also i took of the egr system that helped out. but u might want to check what state ur in first. we don't have inspection in fla.
