I have been reading posts for a little while now. And I have picked up some good info. Considering different synthetics REdline, M1, Amsoil all have different properties would switching brands often cause premature leaks or other long term problems? Im reading on some posts where one oil will cause piston slap and others that dont but over time wear out seals. If this has been asked before sorry about that, but just trying to clarify some stuff thats got me confused.
