Oil life ?

[homebrew]

Got something weird going on, I have about 1500 miles on my current oil change, my oil life went from 80-90 something down to 5% what would cause this??

If it is still clear looking on the stick, I would just clear it and see if it happens again. If there was something critically wrong with the oil you would get a CEL.

Yeah. I don't believe there is a sensor in these trucks that tests the condition of the oil.
