The API stuff is just junk, IMO. And SAE, too. FTM, oil weights on the bottle are mostly useless, as the LL specs incorporate real viscosity measurements based upon actual test descriptions.
You should go to bobistheoilguy.com and peruse some articles. More information than you'll ever need about oil is answered there.

Great tips.
There is a thread in the other forum arguing the told BMW High Performance 5W30 PN 866 is not LL01, since the bottle does not say LL01?!?
It is bad that BMW sells oil that does not meet its own LL01 spec ....
The next oil change is coming up, so I want to find the right oil this time for a turbo engine.
BTW, LL01 means 2001, right? ACEA A3/B4 has many versions, 2004/2007/2008/2010/2012/2016. Which version is LL-01 compatible to?
When a bottle says A3/B4, which version of ACEA it refers to?
