I dont know what it is with the last three to four bars. when those are the only bars left I think my mpg drops to 8-10 mpg . a freinds AP1 does not do the same thing his is way more consistant

 

My gas gauge is on crack too. Always has been. It's a little better with the AEM installed, but it still acts retarded whenver it feels like it.

 

the sudden 0 bars has scared me a few times...

 

i gave up trying to understand my gas gauge a long time ago.

 

Same with my '06. After a fill-up, the guage can still be showing full after 50-60miles or more.

 

^ You are right...I noticed that, too. I drove for quite awhile before the gauge dropped at all. I thought it was broken.

 

Never had that problem at fill up, but the last 1/4 tank is just a guess...

I personally enjoy the 4 bars, then 3 bars after 5 miles, then 2 bars after 10 miles, then 1 bar after 20 miles, then 0 bars after 5 miles, then 1 bar 5 later, then 2 another few later... then straight back to 0.

 

Alright, I've got a new one (to me) that happened to me last week. I ran the tank past 0 bars (the gas light came on), and parked at work.

A couple hours later, I started the car up, drove a block or two, and noticed the gas gauge was slowly climbing from 0 all the way back to full... it took about 20 seconds for it to go all the way to full. Then, as I was driving, it appeared to drop one bar per mile (it dropped 3 bars) that I drove.

I was pretty freaked, so I went to fill up as soon as I could.
