What are you waiting for? Go to Walmart and get them!
If those outstanding Noack numbers for those three types/viscosities of Mobil 1 are correct, don't you think Mobil would publish them? If I was marketing director for that company i would be screaming from the rooftops over my superiority. The fact they aren't published or publicized makes me think they aren't as low as we are being led to believe. If I'm wrong I apologize, but I would still like to see some independent evidence.
Yes, they are correct!
We have known forever from the MSDSs that this trio is fully PAO-based. (All non-ESP and non-FS Mobil 1 oils also have AN according to the FTIR data.) This is not a surprise to us. Aso, the half-PAO-based (according to the MSDS) Mobil 1 AFE 0W-20 has Noack as low as ~ 10% according to the PQIA, which is consistent with the new data for the fully PAO-based Mobil 1 AP 0W-20.
Most companies don't publish their Noack values, as it indirectly discloses their base-oil type. For example if Mobil 1 published the Noack for this trio, they would have to publish the Noack for their other oils, which would disclose that their other oils are not PAO-based. Likewise if Shell published the Noack for both the Pennzoil Platinum and Quaker State Ultimate Durability, they would have disclosed that both oils use the same PurePlus GTL base-oil, even though only Pennzoil Platinum markets it.
What I would really like to have is the CCS value as well so that I can estimate the actual base-oil quality.
I looked at the 0W20 AP and it's msds states 60-70% PAO which is indeed more than I thought it would have and indeed may justify the low claimed Noack number. Sort of curious what the remaining 30-40% of the base oil(s) are. If it was Ravenol or Red Line I would suspect polyols or maybe di-ester's, but I'm not as convinced with the Mobil 1. What do you think the rest of the base oil configuration may be given the available data Gokhan?
I also looked at the other two M1 annual protection products and their PAO ranges from 5-20%. I see now where publishing some of these specifications may be a double edged sword.
Remember that the additive package and VII treat are on top of that 60-70%, so I think you'll find that the remaining percentage of base oil that's not PAO would be exceedingly small.
