Noack 10%Very impressive approval list!
what's the Noack? iirc, has to be below 10. No? How much lower?
also what's up with the 5W40's meeting LL specs but not the 0W40's.
Couple days ago I saw Castrol Euro 5W40 for the first time in store and it also meets LL spec. I bought Castrol Euro 0W40 couple weeks ago and it doesn't list LL.
Noack 10%
BMW increased it oxidation requirement from crazy to ridiculous crazy eliminating pretty much all 0W oils with HTHS above 3.5.
They also usually contain more “true” synthetic base stocks. But, BMW might have some other approval specifications that are not known publicly. Their 2018 update increased oxidation requirements, has specific N20 engine test and timing chain protection requirements. So, for older engines like I have, anything MB229.5 or Porsche A40 will cut it.curious, do the 0W40's fail the stringent oxidation tests because of higher amounts of vii?
Just to be clear though, the grade itself does not have any particular meaning in regards to quality. Only the approvals, certifications and licenses lend that.curious, do the 0W40's fail the stringent oxidation tests because of higher amounts of vii?

Why is LL important to you? Are you driving BMW?btw, I ran into a LONG thread from 2 years ago as to why Edge 0W40 lost LL-01 ... it would be nice to know the conclusion short of having to read 13 pages. lol When I get some time, I may read it.
maybe @kschachn knows the final answer.
It is just a curiosity on my part than a concern. I recently bought some Castrol Euro 0W40 (no LL-01) and then saw the op's Valvoline 5W40 approval list with LL-01 and also noticed store had Castrol Euro 5W40 last time I was there with LL-01 ... It made me wonder what's going on and why neither the Castrol nor Valvoline 0W40's (also M1?) have the LL-01?
