Leaky differential please help
You really can use any quality gear oil out there. I use Valvoline Durablend in mine. It's relatively inexpensive, but still a decent product. Others use Mobil1 and Royal Purple, but I change mine often enough that I don't see the need to pay the premium price.
I used a higher weight than necessary but a generic. However, I have 37k miles on a 2008. So I don't stress it much. Also, I plan on upgrading diff covers before long and then I'll think about Royal Purple.
