If BMW were in fact chasing down a problem to mitigate litigation risk by limiting engine oil recommendations, they're doing a terrible job doing so: 1) ambiguously worded info release on newly approved oils; 2) direct questions about LL-1 to BMW NA are given non-or cryptic responses, including reiteration of 10w-60 as the recommended oil; 3) dealers, despite being shown the release, insisting on using 10w-60. The collective impact of which is unlikely to cause the vast majority of people to change to LL-1
Instead, one would expect a large corporation such as BMW to better mitigate risk by making the new oil recommendations unambiguous, by BMW NA directly answering customer questions about LL-1 being approved and safe for the engine, and by dealers getting a clear message from corporate that LL-1 is perfectly fine and is carried in stock.
