Thanks. Is that the Acea A3/B4 full Saps or C3 low Saps version?

The High Phosphorous and Zinc means this is the ACEA A3/B4 version right?
Yes, high ZDDP (P & Zn) plus high TBN (Ca & Mg) makes it the A3/B4 version.
Everyone here that runs 3-5k mile oil changes on 2019+ Subarus show 3-6% fuel dilution. I highly doubt 10k is doable without copious amount of dilution.
