Re: Hummer H2 Differential lubricant
I am not aware of any 75-90 that meets the GM spec. As mine is still under warranty, I used genuine GM when I changed it. Wild that they actually make it smell like grapes! Assuming this is so it is easy to determine if it is GM or not should there be a warranty issue... NOT cheap stuff either!
When my warranty is up, I will switch over to Mobile 1 75-90W though...
