Taken from some google'd site:
Mobile 1 is no longer a TRUE FULLY SYNTHETIC:
"Mobil 1 used to be made primarily with a group IV base stock which is mandatory for any product to be called synthetic in any country except the US. In the US Group III base stock which is made from purified Pertoleum is all that is required to be called a Sythetic, which is what most Castrol Syntec oil is made from (German Made Syntec is the exception as it is made from GIV stock).
Group III base stocks are very good oils. Castrol GTX from 20 years ago used to be made with Group III base stock and it was the best performing "regular" oil available, but that changed when Syntec was introduced (same product and GTX used to be but different bottle)
Some True Group IV Sythetic oils are Redline (GIV and GV), Royal Purple, Amsoil, German Syntec and others "

Do you have a date on when Mobil 1 switched the base oils? Was there not something similar to this a few years back?
Does anyone know what Mitsu is saying about that? Do they still tell us & dealers to use Mobil 1 or to switch to a different brand "synthetic" oil? Is there a TSB on that?
If not, and based on Mitsu's history of being warranty void happy for everything, I'm sticking with Mobil 1 on my stock EVO just to prevent giving them any form of excuse should anything happen. When a TSB is released that tells people to change oil brands, that is when I will switch.
