Hello, anyone have a best  oil additiv I could use for
my differential. I bought 75w90 castrol syntex oil
for my differentials ( front, middle and back) but i
hear that i have to use oil additive for the middle
one to reduce noise and vibration. Anyone have
any good additives they could recommend me?
Thank you

Sturaco, and I believe 38ml only added and only use in mid diff, to rid noise of Quattro clunk at very low speeds on full lock etc. Only recommended by Audi if fitting new components otherwise 75w/90 to be used. Have heard it being used in all three diffs and all good, not to be used in sports rear diff
