Wanting to go with some synthetic 20w50 for my 2011 SE 2760hp. Yea I know conventional oil will work but going to try and keep this ZT for a while. Those that are using 20w50 syn oil what are you using and where did you get it? Right now all I can find is online and consists of redline,royal purple, amsoil and of course the motorcycle oil but those don't contain friction modifiers that are in automotive oils. Thanks!
