Hey I was just wondering how many KM's per tank a 2000 SIR is suppose to get. I have half a tank left and got 200km so far, I figure I'll be at high 300's before the light comes on. Is this right? I know the car rev's high but shouldn't it be more than that? Also, I'm not driving harsh either, switching at 3000 with a little full throttle.

That sounds about right. I get about 450 to a tank on my Si, and I'm sure that B16 of your's may use a little more gas. Maybe you need a tune-up.

maybe I do, I figured the guys I bought it off of would have done that before they sold it to me, i checked the oil it looked clean along with the air filter so i figured they did it all.

My car ran way better after I got it tuned. Maybe you just need a new fuel filter. It could be clogged. Dump a few bottles of fuel system cleaner in your tank. See if that helps. There are tons of threads about tune-ups.

I see, I'll do some research. Do u think I really need to replace my fuel filter? my car is a 2000 with less than 20000km on it.

DumbasSi

I think at 20000kms, you shouldn't even need a tune up then. My car didn't get it's first major tune-up until 50000kms. Then another one at 95000kms. The previous owner of your car could have been using bad/cheap gas. I'm sure once a few more people read this post, they might give you some better insight.

off a old 93 I get 450 to 500 km to my small tank ... you guys sure seem to be sucking it back to me

DumbasSi

For mine, thats the minimum with the A/C on. I very rarely drive it till the light comes on though. Besides, that old '93 is alot lighter then either of our cars isn't it.

I used to courier with my car and I got 500km off my Si. Now with a full tune up I getting a little better. Should be right for our cars DumbasSi, but then again, you have mods right?

DumbasSi

Just intake and exhaust. I used to run out of gas in my Golf all the time (broken gauge), so now I fill up just below tha last quarter.

I have a 91 DX and i get around 450-500 off cheap *** regular gas

B16A_SiR

well when my car was brand new i used to get around 500 on a full tank and now with a busted o2 sensor i get under 300 a tank lol i really should get the thing fixed hahaha ya ur running about right what i have noticed is that when u hit half tank mark gas goes really fast i drive the same thing

EL_Sport

Your mileage doesn't sound that far off. I get about 200 km to a half tank on my EL, although that is mostly city driving in relatively heavy traffic.

SiR-Racer

that sounds about right. i get about the same mileage

imported_cbishun

thanks for the input, I went to install my springs today and noticed that the car had a full exhaust from front to back. I didn't know that, maybe that could be why it is a little lower?

i have a 93 Si hatch with a 99 dx tranny and i can get 650 kms on a tank... even with redlined shifts every now and again... i dont know how that happens though cause it hasn't had a tune up in a long time.

imported_SiR_YO

what grade gas do you put?

I have a 02 SiR, and for I vary from around 200-250 at half, I usually end up at around 450km per full tank, but I think my tank is bigger than yours.. not sure?

I also use Ultra 94 at Sunoco, and drive moderately hard.. but then again it's a NEW car.. only 2500kms on it

punkindrublic

i used to use the 94 ultra from sunoco and i'd get like 600kms or so... but then one time i couldn't find a sunoco so i used petro canada's 91 octane stuffand thats when i started getting 650+ kms... not sure why a lower octane gas does better... maybe they put more ethenol or something cool into the mix

but having the newer dx tranny really improved millage... cause it revs like 500 rpm lower at any speed in any gear then my old Si tranny... for some reason the car is faster accelerating also dispite the taller gears...

punkindrublic

also my car has 275 000 kms on the motor.... and it runs mint... the old tranny blew but the motor gets redlined daily and still purrs for more...

imported_SiR_YO

Petro =

Sunoco =

lol.. maybe I'm biased b/c I have CAA

I feel my car has better pickup with the higher octane though.. guess depends what you're looking for.. milage or performance
