Looking for some input on different 75w-90 gear oils. It will be used on a 21 Subaru outback and 24 GMC Sierra 1500. I've used Amsoil severe gear before in the Subaru but just trying to stay away from Amsoil. Mobil 1 looks great but Pennzoil platinum has a better pour point. Vehicles are driven in MN winters. Mostly looking to stay with local off the shelf products. Just not much info out there on either of these brands with real world use.
Considering these below in 75w-90
-Mobil 1
-Penzoil Platinum
-Valvoline
