Manual 5 speed, '96 A4 2.8 12v

I'd prefer an upgrade from the OEM fluids. I don't drive in very cold temps. Does the following sound good? Does anybody use those?

Tranny: Redline MT-90
Rear differential fluid: Redline 75w90 GL5 oil

In the tranny only use GL4, in the rear diff GL5 is OK. Never use a GL5 where there is yellow metal. The extra HP additives will cause it to oxidize, and fail.

I use NEO Synthetics in mine. 75-90 in the rear diff, and RHD in the tranny. RHD is GL5, but is OK for tranny use, read the spec's. Also I have steel synchro's so it doesn't matter.<ul><li><a href="http://www.neosyntheticoil.com">NEO</a></li></ul>

What's the advantage of using NEO 75W-90/RHD instead of NEO 75W-90/HD? The RHD seems to work with limited slip differentials?

Also, wouldn't the HD work just fine in both, the tranny and the rear differential?

Considering stock fluid is good for what 80-100k? Either should work fine.
