Saturday I took an hour drive and the car drove amazing, no issues or CELs.  In the morning I had this notification from the my Cadillac app inbox on my phone.  I checked the dipstick and the oil was full, no visible leaks and the oil looks clean.  The app says 83% oil life.  The car hasn’t been serviced yet.
I don’t know what to make of this, and it brings up a question, how is oil life calculated on a GM product and should I be concerned?
