I'm looking to service my transmission and differentials this year and will be going with Amsoil fluids for all.
I have the anti-spin axle and per Amsoil's product finder it says the additive is needed (specifically the mopar additive). If I go on the page for Amsoil's own Slip-Lock it says that all of their gear oils do not require the additive.
Can anyone definitively say that the additive is needed or NOT needed with the Amsoil Severe Gear 75W-140? It seems Amsoil itself doesnt really know, and/or their in house LSD additive doesn't meet the spec called for by mopar as they have no suggestion for their own product and specify the OEM additive. I'm leaning toward just biting the bullet for the expensive Mopar additive so I don't service the axle and grenade it shortly after.
