One wouldn't be able to tell what additives a particular oil blender would reduce to achieve LL-04, but for eg, anti-wear additives like ZDDP would be removed or reduced.Wiki: Zinc Dialkyldithiophosphate (ZDDP) additives, which typically also contain calcium sulfonates, are available to consumers for additional protection under extreme-pressure conditions or in heavy duty performance situations. ZDDP and calcium additives are also added to protect motor oil from oxidative breakdown and to prevent the formation of sludge and varnish deposits. Another important additive is friction modifier, of which the most popular is molybdenum sulphide. That would also have to be reduced. Hydrocracked base oils have some inherent SAPs, but PAO base oils have none. The SAPs are in the additives, which typically make up 20% of modern oil blends by volume. The base oil used for LL-01 and LL-04 oils is the same stuff, so to meet LL-04 standards, the SAPs come out of the additive package.I believe both Syntium 3000 LL and Helix Ultra AB are LL-01, so the SCs are giving us LL-01. Is LL-04 higher priced? I thought the Nissan SLX is about half the price of BMW Syntium and Merc Helix?My point is, don't go blindly for LL-04 if you don't need it or in fact, don't even know what it is. Ask yourself: are you driving a diesel, with Euro 4M particulate filter, and using Euro 4M fuel, in a country with Euro 4M emission laws? If not, why do you need LL-04? <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
