Thought you all would be interested in seeing a VOA on Mobil 1 5W-30 EP, with particle counts and TBN.

This is the SM version that is why.

Yes I know it's SM.
I would expect to see lower Z an P, but was commenting how Mobil went further and lowered other additives as well. AFAIK there is no upper limit on Calcium and Boron.

All the money they pay their retired CEO cuts have to be made some where.

If you wanted to use that argument with every thread on this board, you would have to basically eliminate 99.9 % of the board members and be left with basically a handful of people. It would be a fairly boring place.
A layman can trend whats been happening with a particular oil through each iteration/formula. Great example is with this thread. Even if a simple VOA doesn't tell the whole story it gives us a hint of what's going on. Some people will see a pattern and start to connect the dots with what information is available.
For all intensive purposes this formula looks weaker from an additive standpoint compared to the older SL formula with this simple VOA.
Is this formula different? Yes. Could it perform better? I don't know.

Yes, fiction is often more interesting than facts.
However, an elemental analysis by itself cannot rank motor oils since it does not measure base stocks or non-elemental blend stocks and additives.

And, of course, that this or that oil is "weaker" - which in the context of an elemental analysis is meaningless.

True, there are many additives that do not show up.
