Ok so i took my Z for an oil change around 3-4k miles i think around there?... and the navigation popped up a notification saying "Maintenance Notification, Maintenance item: Engine Oil"..... so does that mean i gota take it back..... or is it just the program setup or something?..... help plz.....btw i just hit 6,000 miles.

its only a reminder , you dont have to take it back for service
check navi owner's manual...

 

On the info screen click "oil". There's a "reset"
