Thanks for adding that in. The LSPI resulted in the reduction of the Calcium (a detergent) in the oil.

I would stick with the TOYOTA recommended SN grade oil and stay away from SP grade oils unless they are backwards compatible with SN and SL oils. SN+ oil was an interim grade oil while SP was written and tested.

SP was written to address LSPI , SAP’s, which destroy the catalytic converters and clog the particulate filters in the exhaust. Supra’s in the USA do not have particulate exhaust filters. And timing chain wear because car manufacturers don’t want to update the material, double row the chain, or modify the lubrication process. Sounds like the GM 6.2L disaster. Just change the oil and don’t address the root cause of bad engineering.

While SP grade oils have 1% or less SAP’s the SP grade oils also have significantly reduced amounts the critical anti wear additives zinc and phosphorus. Also responsible for rendering catalytic converters non- functional. From the few VOA’s I have looked at there is a 10-20% reduction in these anti-wear additives. It also appears some manufactures are adding more Boron into the oils to make up for the lower ZN and PO. I am in the process of understanding the increase of Boron in the oil.

Again, I would stay away from SP oils unless they are specifically labeled SP, SN+, SN and even SL. Or have a VOA in hand to compare to the SN grade.
It just not that complicated.

I have a couple of different brands of sneakers. I have options and buy ones that fit my feet. I’m not going to send my socks out for testing and debate the amount of sodium, sulfites or any other residue left behind in them. My feet will be fine and I can still run in all of them. Your car will do the same. Pick one with the BMW approved LL-01 and use all your new found time to solve world hunger, global warming, cancer or something simpler than all the heartache this topic is causing for ya :bonk:

Tell me how LL-01 an SP (I believe) oil is acceptable when it doesn’t even meet the owners manual requirements. Having experience working on the Indy turbo offenhauser engines running at ear piercing 9500 rpm and then the cosworthengine I don’t just open a bottle of oil and dump it in! That is plain and simple stupid.
