Differential fluid change on a 2017 - 2020 ZL1

Almost 2400 miles on the ZL1 so its time to start getting rid of some of this factory fill fluid. First thing is the differential fluid. I use Amsoil fluids for this most of the time but this time decided to go back with the factory fluid. I don't know too much about the ELSD diff in this car so went to the dealer for fluid to be safe. Man chey really loves this fluid, its absurdly expensive. Part numbers shown on Bottles from dealer - Dextron LS Gear Oil / SAE 75w-90 GL-5 10-4034 88862624 - part number as shown on invoice.
