Mobil 1 ESP Have BMW 04 Approval

[edyvw]

It seems the new formulation of Mobil 1 ESP 5w30 (API SP, LL-04) has no molybden and half of the boron it had before. Also, the base oil has changed (looks cheapened).

Some hidden magic not based on metals or just cost-cutting?

Companies will always try to make thing cheaper and achieve same ir better results. That is why you have approvals. It is minimum that is set up.
This blend allows it seems less oxidation, which was an issue around LL approvals and Mobil 1 oils.

kv 100 ,on paper is 11.9..on this analysis is 12.9.

@Petr why not both?

Not 12.9, but 12.29.
That falls into the "typical" value. All blenders have language that says typical value as it is impossible to get the same KV100 for example, every time they blend certain batch.
Also, VOA is generally bit "off."

correct i skiped a number. now we are waiting for a used oil analysis ,from the same guy perhaps ,to see how this new synthesis is doing.

Whatever you are attempting here, a used oil analysis isn't going to show how the oil is doing. You're very far away from this degree of conclusion from such an analysis.

what exactly do you think i am attempting here?

i am still all ears for your twisted answer, as always mr

Oh sorry, I missed the question mr.

So what I was thinking was that if it's TBN "to see how this new synthesis is doing", then that's not much of a concern there in Europe is it? Or do you have a problem with high sulfur fuels?

And if it was wear "to see how this new synthesis is doing", then you do know that a used oil analysis does not make comparative wear determinations between oils, right? Completely an inadequate tool for that job.

And if it's things that are quite specific to "to see how this new synthesis is doing" in terms of base stock, such as oxidation resistance or deposit formation then what would you look at on the used oil analysis for that?

Maybe I don't understand what you mean by "to see how this new synthesis is doing". Can you explain?

if you had asked me that first, then you wouldn't have to write all the above..i am glad ,because we are not used to seeing you write so many sentences anymore ..and this time was not necessary to..
now, what i meant is just to see whats in there. ..znic,,calcium etc... and how they are reduced and so on, simple things ,what a used oil analysis can really tell us. just for the knowledge of it..
i know your opinion about used oil analysis. even though i do see the used oil analysis i really don't pay much attention .first because someone who does an OCI every 4.000 miles or 8 months and uses an oil ,probably the cheapest on the self with approval then there is no reason to check a used oil analysis.
i know from personal experience that an oil that is good for someone might not be good for my engine, i don't know why but it happens ,if you remember we discussed about this earlier.
