Will performing my own differential fluid change void my gm extended warranty?
If I use another brand for differential fluid such as RP, Amsoil, or Mobil1, will it void my warranty?
I have been told too many different things by professionals in the auto service industry. Changing my own differential fluid shouldn't be difficult nor expensive!
