I had posted on the A6 forum couple of days ago about the trasmission differential and transfercase fluid required for my tranny. I have been told by a member that they are 75w90 Mobil 1. I was looking at the ZF website, and I found the following note by my 5hp24a transmission oil type.

(1) Fill differential and transfer box with gear oil Burmah SAF-AG4. in addition, Sturaco fm 1992 is needed in the transferbox.

What is the correct fluids for the Rear differential, the transfercase and the front differential?

Does anyone know what is the equivalent to the Burmah fluid and whether i need the sturaco additive?

I have a 2001 A6 4.2L with 5HP24 transmission. Thanks
