Oil change at 1000ks is in my 05 euro service book,no oil filter change,but i insisted it be changed anyway.Good idea to do it every oil change.Make sure you use a genuine oil filter too.No,not because they are any better than a Ryco,because if you have any engine problems related to lubrication while under warranty and the dealership/manufacturer notices you use non genuine oil filters they can knock you back on warranty.
I know......i've done it!!
