This is the newest iteration that is marked Dexos1 Gen3. According to their PDS:
the viscosity should be 11.3. This sample weighed in at 10.5. Overall a pretty decent looking additive package, typical 6.5ish TBN and oxidation of 6. According to Lake Speed, a bump in oxidation in high mileage oils indicates presence of esters as additional seal conditioners. I don't know what the oxidation value of the non-HM version of this oil is, though.
