Hi Folks,
2023 Subaru WRX Sport FA24DIT 6SPD Manual
I asked for fuel dilution to be done specifically by Gas Chromatography even if oil was in grade.
Lots of copper... is that normal for these? Factory fill sure was thin.
I understand other markets use different oil grades, are they installing specific grades at the Japanese factory depending on the intended market for the car? I would have thought they would just use one for factory fill, but who knows.
What would be considered lowest allowable viscosity to be considered 20 grade?
Attached are UOAs:
-Factory Fill, dropped at 1793kms
-1st oil change that I ran until 8419kms - Castrol 0W-20 Synthetic SP
