Both of these issues in my POV was a QC/shipping issue with Harrop being in Australia and me being in Hong Kong. I'm sure these minor issues has been fixed now because no one else has had them.

I have an oil change every 6 months or 5000km, whichever comes first, with 9 litres of 10w60 oil. No issues whatsoever.

Did u sell your SC?
