For 6000 Km mileage, I would suggest to go for any of 0w-20, 5w-20, or at max., 5w-30; fully synthetic engine oil from any of Shell, Total, Kixx, ZIC or Caltex / Havoline.
Just ensure that oil + oil filter is 100% authentic, and change oil + oil filter after every 5,000 Kms / 06 months; whichever comes 1st.
If oil level drops in-between, simply top it up.
