I just came across a rather old (between 1989 and 1993) sealed bottle of Mobil 1 Advanced Formula 15W-50. It's rated SG, SF / CD, CC and CCMC G-4.
I would be willing to send a sample to someone who'd be willing to analyze it for free to provide some information about the additive package of late 80's/early 90's Mobil 1. Just send me a personal message if you would do this and make the results available on this board.
