Interesting the HTHS is higher for the 5W-30 than the 5W-20. Must not shear-stretch in the journal bearings? Since OCI's are shorter for GDI engines, I'd think about going with the 5W-30.
Even if 5W-30 does permanently shear in the power cylinder / valve train HTFS areas, the resultant sheared junk gets drained with the OCI. Worst case you end up with a 5W-20 by a 5,000 mile OCI.
If it's API SN-Plus or SP then it's developed to help prevent LSPI events. It's mostly implemented with a balanced Ca / Mg detergent package and limited (if any) Na detergents. It's mostly independent of the base oil.

It's SN Plus and makes specific mention of LSPI mitigation on the back label.
That is Interesting!
Though quite believable - -
HD30 is an excellent oil for many applications that people wouldn't think to use it in.

IRC a "conventional" oil is better at LSPI prevention over PAO.
