Its showing 0% oil life on my 06 impala what does that mean?

the PCM brain does all that magic
the life is based on may factors (an actual equation)

start ups cold, count. or hot. engine.
city miles or high way miles
engine overheated times
or if out door air (ambient) is -60f or 120F?
if AC cold HVAC is used.
and TIME. (oil may be deamed bad at 6 months (IDK)
idling times
allowed to misfire and not do a tune up can change this.
and more, ask Chevy this, directly.
if confused get the car serviced and checked out, and fully scanned for DTC errors,
is the PCV valve clogged up,
does it burn lots of oil.
does oil get dirty fast?
you never said how many miles you run your oil ? 6k ,10k,20k ,more?

engine moter oil should be changed every 3000 milesor 6months . the 6% is estimating you are getting close to your oils peak performance and should be changed soon.

Check the oil

It is probably telling you that the oil needs changing soon. The wrench is telling you it needs service and the 15% is probably stating you have 15% of life in the oil left, with 0% being the oil has to be changed. Most newer cars recommend the oil is changed every 3000 mi or 3 mo.

Hope this help (remember comment and rated this) TY for using Fixya.

Hello, my name is Ben. I am thinking the person who changed your oil probably didn't reset the oil life. How many miles was it between this most recent oil change and the previous one?

i change my oil and filter every 9-10k. oil doesn't were out it just gets dirty.

nearly time for oil change

I have an 05 impala and there is a setting in the Radio to reset the oil life and TPMS system, I'd look in the owners manual to see how to access this feature on the 06 but it should be there.
