When topping up, use what's in there (as long as it is acceptable, as it 
is in this case).  Flushing and refilling, use whatever you prefer.  On 
a non leaking system, it's not much more money to use goo2k than PS 
fluid.  And it's a pretty green.  Green PS, blue coolant, red brake 
fluid... keep 'em guessing!
