Best oil for gearbox

[220bhp]

I am about to change the gearbox oil on my s6. taking into consideration that its done almost 200,000mls what is the best gear oil to use.

Redline MT-90.

Redline MT-90.

Has anybody used it with success? I have few articles about it, but have seen no success stories on audi. Kind of complicated to get here, so it is interesting, is that oil worth all the hassle.

I have it in my box, works fine shifting is smooth.

I just got the OEM VAG stuff to do things properly 160k and no probs.

I don't use it as a cheap alternative. Redline oil is just about the best transmission oil money can buy. The MT-90 stuff is probably better for the synchros whilst still giving a better shift than the generic OEM stuff.

I definately noticed an improvement but then i was comparing to old oil.

Anyone else confirm this or am i talking bull?

Anyone on hear useing synthetic oil .

Erm, I wasn't commenting on your use of redline products, I am aware that they make perfectly good transmission and other fluids. I merely commented that I have replaced my oil with the correct OEM stuff from VAG stuff and it's fine. If I were to do more track work then I'd use a thicker aftermarket alternative.

I try the oil that Ferrari uses fro their gearboxes wich is Shell and the gearbox was crap...
Then Castrol (don't remember the name but anyway the best from their range)
Gearbox was crap still....
The original from Audi it's in now and gearbox it's just perfect.

I use fully synthetic in the rally car box. Seems great.

I used castrol TAF-X on my Coupe (sold) and my Urs4, works just fine. Better response in the cold at least.

I have used silkolene SILKTRAN SYN 5 75W-90 to great effect.

But there are many more
