Oil Change

["Kappy" <bmkaplan@eniac.seas.upenn.edu>]

I am about to change the oil in my 1989 200TQ. The oil has been in there for 
3k miles.  A few questions:
	1) Synthetic or Natural?  Which Manufacturer?
	2) What brand of Oil filter?  
	3) I read in my Haynes Manual about a turbo filter as well. 
Should this be changed now, or can it go longer?  If it should be 
changed, who makes the best?
	4) Is 3k miles too long or too short a time between oil changes?
	
Thanks in advance for the assistance.
