I'll bite.
First, there is some wear always going on; you must've seen some shiny brass 
flakes in the oil.
Second, any oil has certain additives that wear out with heat and age.
Third, the oil sold by Audi today is likely very different from the factory 
fill back in '90 when our trannies were built.  Funny how Audi uses one part 
number for any manual tranny oil... so, has every audi manual transmission 
from the first quattro to today required the same stuff, even through 
different tranny manufacturers?  So, it's probably a synthetic made by 
febi/bilstein or the like.

I've used the redline before.  On my old 4kq, second gear was very balky; 
changed first to synthoil; no change.  Put in new audi fluid; no change.  
Tried redline (next step was the used tranny) and it went back to like new; 
worked great for another 80k miles.
