i have the 01 4 dr civic. i used to get 600-650 km/tank. but now i'm only getting like just over 500 km/tank.

the spark plugs were just changed 2 weeks ago.

any thoughts? what happened to my baby?

cold weather affects every cars fuel efficiency, funny thing is when it was hotter i used to get those numbers too but when it got cold - i just get a lil over 500 kms/tank

tune up. like rjngo said tho, its cold weather, you cant expect the same mileage u get in the summer.

also heres sumting helpful for your car's maintenence.

check for dragging brakes, check your tire pressures, and finally you can use a scan tool to check all your sensor parameters.... make sure the O2 is working and so on. but beyond a basic tuneup... not much you can do if everything else is cool.

but it is true, I get about 100-150 kms less per tank in the winter as well depending on how much hwy driving I do.

but this has been happening for a while now...like throughout spring and summer.

ok, thanks for the help guys...i see there's another thread on this as well.

what kind of plugs? OEM? Depending on the mileage since last tune up i would say fuel filter

Im not sure about this but what abt the timing... i know you can make the car run rich or lean by changing the timing. can hers be off?

imported_Shazza

you mean the timing belt? ya, i gotta do that soon i think.

1sykcoupe

no Im not talking about the timing belt. If you look at that website I posted, it'll tell you wen ur suppose to do your timing belt. that maintenence schedule if specifically for your car.

lol how are you guys getting 600km on a tank?

I drive a 97 Si and i'm happy if i can squeeze 400 out of the tank

1sykcoupe

then ur the one with the problem lol. getting to 400 should never be a problem with a civic. I average about 450 -500 depends on how and where im driving.

kwasley

i average 350-550 on my single slammer

1sykcoupe

lol das quite the broad average. We're talking about after a full fill up.

Pyro

haha yeah after a full fill up....i'm happy if i can get 400km....

i usually get around 300-350km a tank....could it be my mods on top of the fact that i'm not the most economical driver? lol

check your air filter, could be really dirty
replace it or clean it if its aftermarket

driving habits play a big role in mileage. Someone who drives only 5km or so, per trip, through the city , won't see the mileage of someone who drives a lot on the highway.
I get about 450kms to a tank (i fill up at about 1/8th left, sometimes a little less) pretty consistantly of mixed highway and city driving on my b16. I don't drive like a granny, but i'm not constantly beatin on it. B16's aren't exactly the best on gas (from what i've seen) even stock, mines about 11.5:1 compression, built head, stage 2 cams, so mods don't really make ur car worse on gas. Sure, if its faster its likely using more gas (due to the fueling needs of higher output engines), but tuning plays a big role on modded engines.

you wont' need valve adjust or t belt

check your tire pressure and air filter

imported_Shazza

air filter changed when i changed the spark plugs a couple of weeks ago. also changed oil/filter, a/c filter, ATF...tire pressure is ok i'm sure.

ya, i dont know what affects milleage...mechanically speaking.

as for my driving habits...the same...if anything, i'm less agressive. my driving route is the same too.

got close to 535 km off this week's tank with 8 L left in the tank.

Pyro

i'm not afraid to admit, i have some bad driving habits...okay fine only one....speed

aside from that....filter is pretty much brand new....bought and installed in july, just corrected tire pressure like two weeks back
