What RTV is better for my oil pan? Permatex Red high temp or Prematex Ultra Black maximum oil resistance sensor safe?
It's for a 2007 Nissan Altima

The Ultra Black would be better. I did an oil pan which the gasket set was just the seals and a couple of tubes of RTV

The oil resistant O2 sensor safe one would be better. Use it sparingly as oil resistant is not oil proof and you don't want boogers hanging down inside as the will come loose sooner or later.
