I don't know how often it got changed in the first 100k-- but my
daughter just traded in her perfectly running 1997 Grand Am that she
changed when the dash light told her to. It had over 250k on it &
didn't use a drop of oil.

My Impala has 130k on it & have been following GMs recommendation to
wait until the dash light tells you it is time. I don't pay much
attention to it any more-- but while it was still making me nervous,
it would run 6-8000 miles between changes.
