If the car reads the oil break down it should be in 15000. This doesn't compute who is lieing
No one is lying. The system's ability to detect a problem with oil quantity is very limited, and that is not what the CBS normally tracks. There is not a sophisticated lab in the oil pan that is analyzing the oil.
Doing an oil change between the ones the CBS calls for does not change the countdown. Or to put it another way, the fresh oil is not recognized by the CBS. It is not that smart.
