My Jeep is in the shop right now getting gears done, and I need to know what type of gear oil superior recommends for their 5.13s??? Anyone know? I don't want to buy royal purple or similar for break in, when it will come out in 500 miles. But I want my gears to last. The shop said it is supposed to be something synthetic, they think. They said they don't think superior recommends the factory oil, and that could cause failure. I have to supply all the parts (which keeps my cost down) so I need to know ASAP.

I called superior, but they have not called back yet. HELP!!!!

 

No ONE???? Someone has to know?!?!

 

What LSD do you have? I have an aussie locker going in the front, I don't think it requires any special additives?

 

its not cheap

 

Kinda like toad?

 

lmao.... I so almost called you cheap. Be glad you said that! haha. I didn't want to run Royal Purple only to drain it out in 500 miles. After break in is another story. David @ Northridge called me right after I got ahold of Superior. They both said 80-90 weight GL5+. I bought some Valvolene 80-90n and dropped it off. Thanks Malo, David, and Superior. You other guys... Thanks for the laugh. lol
