Aren't these A3/B4 oils with high ZDDP by US standards?
Studies have shown that high ZDDP (meaning higher than US SN/GF5 oils) can be a powerful mitigator of LSPI.
I was even going overboard and putting some ZDDP additive in my oil before d1G2 with an LSPI test came around.
That said, I would still be more comfortable running something I knew was low in calcium.
That 0W40 Ca level looks OK by the VOA posted, not sure where that 0W30 would end up.
I used M1 5W30 ESP Formula a few times, probably somewhat comparable in general to your 0W30 and I knew from VOAs that it was low in calcium (~1200) like most of the M1 line (0W40 excepted).
Is your daughter an aggressive driver?
LSPI is mostly a low rev phenomenon, if she grabs some revs when she gets on the throttle it is probably a good thing for the health of that engine!
