Change it. You can run synthetic for longer before it starts getting dirty, but it wouln't hurt to go ahead and do it.

Synthetic or not I still replace mine every 5000kms weather its dirty or not :p who knows what contaminants its picked up.. and for $15-20 for the change gives me piece of mind that I'm not going to do 1500-2000 on blowing an engine due to rotton oil

and the only time the oil light comes on is when its EXTREAMELY low (when that light comes on it means theres under 2quarts of oil on a BMW) OR theres low oil pressure

get royal puple and change every 4000 miles
Or you could get mobil 1 or castrol syntec and not waste your money on royal purple.[hihi]

XD I can pull that mileage off in just shy of a month hehehe hence I go for 5000kms (I have a logbook of everything done, the mileage at every service and the mileage of every part installed hehehe
