anybody use amsoil 20w-50 z-rod in their car, only in warm weather I know but this stuff is for high performance motors and it protects from rust when it is in storage for awhile, at least thats what the website says, want to get rid of ticking this summer and using 15w-50 or around there is what I hear takes care of it. if not what does the majority say?
