Re: Have you heard about the end of 0 weight oil?
Mobile 1 is no longer a true synthetic oil. Most oils marketed as "synthetic" are really nothing more then a highly refined petro oil. In Europe oil cannot be marketed as "synthetic" unless it truely is, but of course here they can market anything as anything, so anything goes.
Amsoil is a true 100% synthetic oil, so it is a better choice then Mobile 1.
