I drove my 2006 Civic Si for 200k+ miles while following the maintenance minder only. Average oil changes were at around every 7000-8000 miles, and sometimes I even went a few hundred past the indicator, when it would start reading "-" miles.
I never had a single issue with the engine or transmission; for an L4 engine that revs to 8000 rpm, I'd say Honda did a pretty good job with the maintenance computer.
