Which century are you living in?!? The era of cars needing a new
engine at 100k are long, long gone. Anything built in the last 20
years will do 200k on average maintenance.

Which is exactly what I said. regular maintenance good for 200k

I read it as "not doing interim oil changes, only good for 80k."
