Thanks for posting the VOA on Mobil Super Synthetic 5w-20.
Just like the MC 5000, Mobil is using the Action Packed, Sodium Add Pack like Napa Conventional, VWB, NexGen and Castrol GTX, Valvoline SynPower, DuraBlend and NAPA Full Synthetic.
There must be more, than what appears on the VOA, with the cleaning ability of all these sodium add pack oils.
