Final Drive oil..

DO NOT use Redline brand in the diff, it will tater up your seal, it will leak, and you will cry. This is the voice of experience.

What brand(s) do you endorse or use?

I noticed dirt gathering around my fill bolt on the differential and figured I would change the oil while I was changing the crush washer, and inadvertently bought 85W-140W oil. Anyone know if 140w is too heavy or should I go get regular 85W-90W?

I am using Valvoline 75-90 w, full synthetic, purchased at Wal-Mart.

I switched from Amsoil to Mobil1 in the early 90's just because it was easy to find.
