Ok it's been a couple days since I filled up. Yesterday the needle was still on full. This morning when I get into my car to drive to work it was at lower than 3/4, so I'm thinking what the hell. Then about halfway to work(about 10 minutes later) it's reading full again. Has anything similar happened to anyone on here before? My only guess is it happened because it was cold out this morning, but I didn't think it would show almost half a tank less.

 

The general concensus is that the 01-05 civic gas gauges are not very accurate. I dont normally see that much fluctuation when full. However once I get closer to empty the needle will jump around to different positions every time i get in the car. So dont worry too much about it, its normal for our cars.

 

i can read a 1/4 of a tank park my car get in and my gas light is on. Just calculate your millage with the trip a **** thats the best way.

 

weird, ive had no problems with any of my civic's guages. There has been a slight "problem" if you can call it that from 1988-now with civic's bottem half of the gas guage being about 1/3 the size of the top.

I get about 130 KM's once im full before the needle even moves, its a full 400km's befor ei hit halfway, then after halfway i get about 200km's.

 

I guess it's a good thing our cars get such good milage.

 

yeah my guage may fluctuate at times

 

Yeah, I'm used to a little back and forth, but this was almost a half tank. But when I left for lunch it was still at full. It must have been because it was cold. I guess I'll see for sure when winter gets here.

 

yea it does that. i drove on the freeway with he gas light on and a few minutes later is 1/8 full. with light off.

 

yep...mine does the same thing...i come home and it still reads full and then on start up the next day it reads not 1/4 tank lower but a lot lower than it was before...but after driving it comes back up a bit...

iunno the gauge is just not that accurate...and it is just a gauge

 

yo man. my gas gauges do the same exact thing.

 

Mine will read pegged at Full for almost half a tank and then read normally the whole way down with only a little variation.

 

just remember to fill it up when the lights comes up. and u're safe
