Agreed. A few months ago I sold my 2006 Trailblazer. I followed the Oil Life Monitor, and the oil change interval varied from 4000 to 9000 miles depending on my driving habits.
It should be repeated that relying on the onboard OLM on any car requires using the correct manufacturer’s specification oil and keeping it full. It’s hard to believe that people don’t understand the difference between changing oil and checking/adding as needed.
