Sanity check - Amsoil 75W-90 fine for my diff?

[elChupacoffee]

Hey guys, I just need a sanity check, but I just drained and refilled my diff with Amsoil 75W-90 (PN# SVGPK-EA) and didn't add any additional friction modifier since Amsoil states its already included in the oil. Just want to make sure there isn't any issues running this oil. For reference I have the 2017 GT with PP and 3.73 gears.

You'll be fine. I've been running that in my car for a while now. Some track time using it and no issues.

I won't be tracking the car, very unlikely at least. Just spirited street driving at most.

thanks!!

I would refer to the owners manual for the proper weight oil for the rear diff. That is the only assurance you should trust.

75w-90 is fine. Go with 75w-140 for track use. Add in Limited Slip additive for street use to quiet the Torsen down.

I agree that Amsoil probably already had the LSA in it.

According to the website it does, if I am understanding this correctly.
