I just got off of the Amsoil Online Product Applications Guide and found that they claim synthetic oils will eat RTV sealant in applications such as the rear differential. Is there any merit to this? I was planning a fill of Lucas synthetic 80W-90 and use RTV to seal the rear. Is this not a good idea? Should I buy a gasket instead? I have always used RTV and never had a problem, but I want to make sure I prevent one in the future. I also read about rears with high pinions not being properly lubricated by synthetic gear oils. Would I be better off to use a product such as Penzoil or Supertec and use the Lucas in a field mower gear box or something?
Also, I am going to do a simple drain/ refill of the transmission with Valvoline Maxlife. The guide says the initial fill is 5 Quarts. Is this how much I will replace with a drain and refill? The vehicle in question is a 1996 Chevy Silverado K1500. I thank you for your help!
