my gas didnt go away way up be4 when i brought the car , now it working fine but just i have hole on my exhaust it seem like i am losing some fuel cuz i had 360 miles per gas now it like 260 now i lost 100, did u try fuel cleaner and check the oil ?

 

yup. and infiniti replaced da shutter vavle and that didn't do ****! i think it might b da sending units!

 

alright

 

my 2004 g35x sedan only takes about 16 gallons when it says its close to empty. same problem?

 

it could b....

 

seriously. ???

 

Just wanted to give ya an update w/my situation..
I originally put the Techron additive in when I first noticed the problem about 2-3 mos ago. Since then I've been using strictly shell (no BP).
Well, to my surprise when I filled up today, my gauge reads completely full again!

So have faith guys, it may take a few weeks but the techron does work!

No BP gas FTW!

 

most ive ever filled up was like a lil over 15 gal. i try to use only shell gas

 

Only gas i use is SHELL. My gauge is still retarded sometimes. fill up and it will read 3/4 tank.

 

i only use shell also. and i put techron fuel additives every couple months. today i filled it up cuz low fuel light came on and i can only put 10 gallons now. i got worse!

 

I was only getting ten. Now I get 13.

 

from what i have noticed, dont let ur tank go down til the light comes on, cus when u pump it again, it normally stops 3/4 or around 10-13 gallons. But if fill up before 1/4, it fills up to the top fine.

just something i have noticed.

 

so.... i took my car in today and complained about the gas thing. and the service advisor said they will replace to whole gas tank?!? is that necessary? i honestly think he really doesn't know ****. hes not a mechanic. i just don't want them to **** anything up

 

It's the fuel sending units. I had the same problem (mentioned in my earlier post in this thread) and the dealership replaced both of the fuel sending units and the problem is fixed. They get dirty and start sending bad signals. Using an additive may help some but if they are already dirty then it will probably not get them back to completely clean and working correctly. There is no need to replace your entire fuel tank unless they have already tried the fuel sending units and that did not correct your issue. If they replace the tank but put the same sending units back in you will still be at square one. Not sure why your dealership hasn't checked them before, it was the first thing my dealer looked at. They did that first because it was either check that or the gauge itself and that is a lot more involved.

 

ya i don't trust da dealership in town. i told them b4 that problem could b sending units. instead of replacing da sending units they replaced da shutter valve. and that obviously didn't fix the problem. so when i go pick up my car on monday, i'm gonna talk to da mechanic that worked on it. cuz this service advisor just doesn't know ****!
