How are you checking the oil discoloration?  There is not much oil on the dip stick. From the filter housing maybe? | 
	
 
From the dipstick. 
The Porsche is a little difficult to see on the dipstick.
 So just look at it or wipe it on a whiter paper towel.
Several dips and wipes if I need to.
 My Honda CRV and Ford truck.
No problem to see the oil on the dipstick.
