There is a big sticker on the drivers side door card, where is the mirror. It clearly says Oil should be changed every 6 months or 7500 KM (4687.5 miles) whichever comes first. Same sticker also says that after hard driving, or long motorway journeys allow the engine to idle for 1 minute before turning it off. then something to refer to manual for oil grades etc .

So that is your answer 6 months or 4600 miles. (from a V4 wrx impreza). Best is like guys above suggest is look at the oil, and when it goes black or dark brown is time to change it as is it contaminated.
