Two OCIs:
2019 Subaru Ascent, 30K
Out - Subaru filter, M1 ESP 0W-30
In- Fram TG7317, Castrol Edge EP 0W-20, new Mercedes-approved version. Filter is “old” Fram design, not the E-core.
2019 Lexus RXh, 151K
Out - M1 5W-30, Fram CH9972
In - M1 Hybrid 0W-20, Toyota filter
Yes, going back to thin. The RX isn’t driven as much so it’s back to 0W-20. The Ascent also doesn’t get driven much by the neighbor, it’s her roadtrip and family hauler(she bought a RAV4 Hybrid for around town). While we know Subaru’s FA24F loves to shear oil, any “thin” oil with a BMW/Mercedes/Audi approval tested in a stressed out 1.4-2.0L TGDI I4 might have a fighting chance.
