I noticed a current thread on an automotive forum in which the customer brought in their 09 car due to a check engine light. The customer was told that the reason for the light was a malfunctioning oil life sensor. (The car showed 10% on the GM OLM with an OCI of 12k miles). Furthermore they said this oil was dirty enough that it caused the timing chain to stretch and would of course need to be replaced.
Is this scenario possible?
