Need help making my mind up BMW LL-01 / B46 engine - mindlock

I am not sure you actually understand LL01 specification. Obviously you don’t understand how this works.
I know. Only 5w-40 and 5w-30 oils can be approved. So obviously the 0w-40 would not be able to pass.
 
How do we know that a 0w-40 cannot have the ll-01 specification? How do we know that the 0w-40 was never tested?
Bcs., as discussed numerous times:
1. BMW bumped oxidation requirements to such levels where it eliminated pretty much anything 0W. it eliminated all oils having substantial amount of esters, like M1 ESP 5W30, M1 5W40 FS etc. (LL04, same oxidation requirements as LL01).
2. BMW specifically limited grades to 5W.
manufacturers and blenders cooperate. Mobil1 0W40 FS came out in 2015 and never was submitted for approval bcs. Mobil knew that BMW is going to update approval and what are requirements.
so, again, why would Castrol send 0W40 for approval?
 
. BMW bumped oxidation requirements to such levels where it eliminated pretty much anything 0W.
Any idea why BMW upped the oxidation requirement.

Here is what Lubrizol says. I have no idea if this information is accurate. Just thought I would share.

I don’t know anything about 4200. The only LM listed for the B46 that is 5W30 is Special Tec. It’s unclear to me what the major differences are between Leichtlauf, Special Tec and Molygen (“friction reducing molecules” and shows up in UV light)
First, please let me retract what I have written in post #23. LM 4200 uses BASE STOCK GROUP 3!!! Further research on the LM German website shows that LM uses "synthesis technology" to make this oil. So, I retract my recommendation.

You are in NC so I'd go with either BMW TPT 0w20 (https://www.fcpeuro.com/products/bmw-0w20-ll-14fe-engine-oil-1-liter-genuine-bmw-83212365954) or 0W30 (https://www.fcpeuro.com/products/bmw-engine-oil-07510017866).
 
The "Afton specification handbook" provides significantly more detailed information compared to Lubrizol's comparison tool. If interested just see the "Afton specification handbook".
Edy, while you might be true about 0W/5W and the more stringent oxidation requirements it isn't that simple with/doesn't generally exclude using esters. Factually there still do exist some LL-01 and LL-04 approved oils containing similarly or even more esters than M1 ESP 5W-30 does. Ravenol's RSP 5W-30 (LL-01), REP 5W-30 (LL-04) and RUP 5W-40 (LL-04) coming in mind. Guess it helps meeting the more stringent oxidation requirements by using majority PAO along with esters and AN. Vanderbilt's Vanlube W-324 add pack is supposed to improve oxidation stability next to reducing friction and wear. I still would run M1 ESP 5W-30 without any concern anytime AFTER warranty expired, at least in a world where REP doesn't exist.

See my post #42 - correct. Only group 4 oil is the Synthoil Energy 0W40 but it won't have the BMW approval(s).
 
What is the issue wtih this LM oil? This is what they show for your car, not the LLHT - why is FCP showing that?

 
That's what I was remembering anyway, but I didn't want to argue. Perhaps some (VW 508 00) 0W-20 LM has some PAO too if that matters.
.
Who knows - I like you have spent some time over on their German site and you can tell what is what based on how they label it for sale in Germany.
