Actually longlife OCI's are a primary driver (sludge, TBN) which resulted from new environmental regulations. Of course the ACEA test sequences continues to evolve every year with the addition of more stringent tests which revolve around sludge reduction, piston cleanliness, fuel economy, and emissions (2004 C1,C2,C3).
I think what you'll find is that LL01 no longer meets some portions of 2008 ACEA A3/B4 standard.
