what brand fluid do you use?
 

I put this in FAQ yesterday on accident. I was wandering what brand fluid you guy's use I was thinking of puting Mobil1 gear oil in my rear diff. I am changing the transfer case and my front diff also. I will be doing this in about 2 weeks I have a few days of from work coming up

I would use the regular old oil from the autoparts store, but others have others have their opinions too. I guess it all depends on what you feel comfortable with and the amount of Denors you want to put out of your pocket. Can anyone else expand with some thoughts? Can anyone tell a difference with the different fluids out there?
