Doubt is Mobil 1....Mobil one supplying factory fill for some german manufactures but I have heard no evidence that they are producing oil for Toyota....
Anyone else know about Toyota oil? I hear it is good stuff
You have to ask which grade, as the OEM may vary by grade. The 0w-20 is special with ~ 800PPM moly. There was a long thread on ths oil a couple months ago.
