how often do you change your oil?

just wondering when you guys change your oil and othjer maintenance. i put 800 miles on ina week and a half and was wondering when to do maintenance.

By the book. Not a moment (or mile) sooner.

every 4000 miles my filter and oil get changed, the book requiresit every 8000 but then it also says your air filtyer is clean then and its definatley isn`t. For the negligable cost of oil n filter every 4000 does me well, after all it works hard for me.
