2020 JLU Rubicon Diff Fluid

[MrFenderpicks]

I apologize if i am reposting this but I cant seem to find what spec diff fluid i need for a 2020 JLU Rubicon

As i am looking to replace my Diff cover this weekend. Amsoil web site shows 75w90, but when i look on motobilt site it should be 80w90.

Can anyone confirm the grade diff fluid is required in the JLU Axles?

The manual for my 2018 JLUR calls for 75w85. I recently put some Redline 75w90 in the rear diff and it seems fine.

Also if you're doing a lot of towing I believe the owner's manual recommends 75w140

AMSOIL does list 75w-85 as the viscosity obtained from a 3rd party, but recommends their Severe Gear 75w-90 which they warranty and meets Jeep's warranty.
