i don't think SIRs have a 20L tank....pretty sure they're more like 35-40L.

imported_Joe_98Si

why did you have to make a new thread for this? you already have one going

toofastcrxx

it got closed so i had to start up a new on and i usaully pump about 17 to 18 litles and the pump stops..so i think its a 20 liter tank

zeeman

keep pumping dude.
Would someone who owns a SIR please chime in.
My civic holds like 40L, so i doubt a higher performance model would have a gas tank half the size of pretty much every other model civic.

toofastcrxx

yo i just think it has a 20liter tank...unless my gas guage is broken....Sir owner how big is ur gas tank...1999-2000 sir only

imported_Pyro

i don't drive a SIR but i drive a Si and my car isn't 2000 its 1999 but im pretty sure there both the same thing.. its a 45L tank..well should be..and and i have a GSR engine..and i get about 350 for sure and 400 if im lucky..and the 98 GSR spec and 00 SIR spec for Liter / 100 km are the same thing there both 9.5 for city so something is wrong with your car i think or your tank is messed? or got swaped???? i dunno but yea thats all i know hope it helps

*or correct me if im wrong about the tank size =) *

I used to own a 2000 SiR. It's a 45L tank trust me.

20L = 160km
40L= 320Km

Still a bit low even for the winter time. I would love to see the legit e-test results from your SiR.

Have you replaced your air filter, and pcv valve? When was the last time the oil was changed?

toofastcrxx

so SiR come with 40 liter tanks?
and what u mean by ther pcv vavle and what is it and where is it

PCV valve is the positive crankcase ventiliation valve, which lets the air/oil vapours from inside the crankcase get recycled into the intake manifold and get burned in the engine.
On your car its located on the intake manifold near the fuel rail (between the #3 and #4 runner). It has a vacuum hose attached to it that goes to the intake manifold.

yo starboy does that mean i have a 40 liter tank

unless the previous owner switched it out for a smaller one

toofastcrxx

my buddy gave me an idea...he thinks my guage is messed up he told me run the car till it dies out and it might reset my gas gaugeand if it still only takes 20 then i should get it checked

just take a little 5L gas can filled with gas with you, so that if you run out while not near a gas station you won't be stranded.

toofastcrxx

yo u think thats a good idea tho

zeeman

iTrader: (1)

why not?
Just keep like 3L in there if you're worried about it spilling.
Either that or take the car to a shop and let a mechanic look at it.

imported_starboy869

What I meant was

ON 20L you can only get 160km range. Now on 40L of fuel you should be able to get 320Km. IMO 320KM range on 40L of fuel seems a bit low even in the winter time. Unless you leave the vehicle idling alot, or love being in VTEC RANGE.

BTW: I would try swapping back in a stock intake system just to see where you sit fuel range wize.

Also do that 3L of gas thing just to see if the gauge is messed.

imported_starboy869

Oh,,, one more thing

Which grade of fuel are you using? 91 correct?

I know when I ran 87 (by mistake) once my SiR ran like ***. No pep, and I only got about 400 or 450km to the tank.

imported_ludesrv

20 Liters? Either your tank is seriously dented to **** or you aren't doing something right. 45Liter tanks from factory. They usually get shrunk down (from you filling it up, driving it until she's bone dry without venting it, that sucking noise isn't a nice one) over time to about 43L...but you never let it run till she runs out for 40L is the norm on empty fill ups.

Get your car inspected...then do a tune up...

VTEC_Thunder

I own an 00' SiR.

Not sure exactly how big the tank is...(just google it...lol)

It's at least 40-45L. I know this because i've filled up and put in around that amount.

My guess is your fuel gauge is not working properly.

Like everyone else said....run the ***** right out a gas and take a can of gas with you so you can get to a station. This way you'll find out exactly whats going on.

Also, when the pump stops when I'm filling up I can usually fit in another $5 of gas or so. (bout another 5 liters roughly).

Good luck dude!
