Hello. My suburban has a g80 locker and I'm wondering the correct fluid type. Will this ac delco fluid be fine? The pricing of it sketches me out but it's also a great deal if true.

Was going to do mobil 1 80w90. But I came across this deal on amazon for ACdelco fluid.

Has anyone used this fluid? I'm asking because they have a 12-Pack of it for $25 on Amazon. A 12 pack... considering 1 bottle is $19.

https://www.amazon.com/ACDelco-10-4108-Pack-Gear-Oil/dp/B07CL6MBX5

Heres the fluid I'm question. Says nothing about LS additives so I think it should work.

SAE 75W-90 Synthetic Axle Lubricant (GM Part No. U.S. 12378261, in Canada 10953455) meeting GM Specification 9986115. Any fluid meeting this GM spec is ok. Valvoline, Royal Purple, Amsoil should work. GM 9986115 spec refers to HD Synthetic SAE 75w90 Gear Oil.

I believe synthetic 80w90 goes to the front diff. G80 diff calls for synthetic 75w90. I use amsoil for both, they’re working great and quiet.
