Do the additive products to engine oil correspond to “LSPI” which is a trouble of direct injection turbo engine? If so, please let us know the results of the verification.

We have not been able to verify whether LSPI is applicable or not.
LSPI is greatly affected by compression and ignition timing,
Low friction oil increases piston speed.
Conversely, high viscosity oil causes low piston speed.
However, we believe that there are also effects of internal combustion gas, oxygen content, combustion chamber temperature, and other factors.
We are not able to verify this under such conditions at our facility, so our answer is that we have not been able to verify this.
