    I would use whatever it says in the book. The filters should have been changed already(first filter change is usually much earlier). I dont think they recommend to change the oil though...as it would be impossible to get all the old oil out.

    They probably said 15W50 mobil 1 because thats what MOST of these hydro systems call for.... Probably wouldnt hurt anything by using the 15W50 Mobil 1 in it but I would use whatever the book tells you to.
