Maintenance Required

Maintenance required
I drive a 2006 Toyota 4Runner.
221,642 miles.
The “Maintenance Required” light came on the other day.
Means it’s time for an oil change.
Was driving out to the mountains to look for elk and got to wondering…
What happens if I ignore “Maintenance Required”?
At what point does “Maintenance Required” turn into “Check engine”?
If I never changed the oil, how long would the engine last?
Now that you’re imagining me standing next to a smoldering 4Runner with my thumb in the air…
What’s the health lesson?
