I cannot find a interesting thread on this oil but did find this posted by George
"Mobil's reason for reformulation was for performance upgrade. As I shared in previous posts, the "sypersyn" formulation is for real, having been developed years ago, sat on a shelf gathering dust until one of the assigned racing lube engineer's ran into a bearing life/film strength problem. ie. bearings were failing in the race engine and the engine builders were blaming Mobil 1. He had a batch made up with this particular molecule blend and the problem not only went away but the weak component lived better than the previous strong design. So, by fluke rather than design, the supersyn (don't know where they get those names) was formulation is an evolutionary improvement in Mobil 1's performance. Mobil 1 and Delvac 1 are Mobil's flagship and they are going to do everything possible to keep them one generation ahead of the other major synthetics such as the Castrol/Valvoline/Quaker States of the world.."
I see some of the heavier wts of this oil in the analysis section but am waiting to see a 5/30 or a 10/30 analysis.
Does anyone know if this formulation uses metallic adds?
