Mobil 1 has released the specs for its new "Mobil 1 with SuperSyn".
I have updated my compilation (comparing the Tri-Synthetic with the new one with SuperSyn). See it at
Or go to the Mobil 1' site at
The specs of the new oils with SuperSyn are exactly the same as the SL rated Mobil 1 Tri-Synthetic (which lived for about a month from mid-March to its replacement by the "with SuperSyn").
