diff fluids

[hahnmgh63]

Redline 75w/90 in the front & rear Diffs & Redline 75W/90NS in the center Diff. Not sure why Audi recommends fluid with a Friction modifier in the Center Diff as it's a Torsen so it should just be work gears. I have used regular Redline 75W90 in other Audi's with the Torsen center diff with no problems before.
