Yeah, I've seen it. To me it looks just like one case that became a bit overhyped. Can't find any input on this additive there though.
Anyway, my engine runs quiet and does not show any signs noted in this thread. It doesn't get too much heat with this oil (the operating temp is about 1-2mm below 210F), which I think is also good. I have seen MRF put the LM oil in many of the cars they serviced and haven't seen any bad experience shared by them.
Also, take a look here

The last chart compares viscosity of the LM and TWS. The LM oil is much less viscous in the lower temperatures, which I think is beneficial. On the other hand, it gets more viscous at 90-100 C temps, but still that's just by about 5%.
Is there anything wrong with the additive?
Not a Liqui Moly fanboy, and to be honest I still haven't decided which oil to put for the next change. I will be doing rod bearings then too, so I will probably ask at the workshop for their opinion.
