BMW LL01 testing sequence simply involved running the oil in an M54 Engine (2001 330I) for 370 hours, drain and test for V100, HTHS, and TBN. ACEA A3/B4 is the european equivalent of the american pertroleum institute, and thus their testing sequences are a lot more vigorous. Please do not confuse the two tests. One day, you will stop dodging my questions, regarding inconsistensies in your LL01 logic.

Quote:"BMW LL-01 - Like the LL-98, also required to be ACEA A3, API SJ, and run a 370 hour test, but the test engine is now an M54 and compatibility with the valvetronic system is a specific test requirement. These oils tend to run a little bit lighter than the LL-98, with a Kvis100 range of 11.3 to 14.1, averaging about 12.3. HTHS averages about 3.6, TBN about 10.4, and density about 0.849."
