Sent my car for the 10,000Km servicing at Borneo Motors today. Changed to Synthetic motor oil using Castrol Syntron Extra 5W50 (4.2litres). Synthetic oil information can be found at:

Complained that the car has difficulty in starting in the morning, ended up, they changed the car battery for me. Total costs: S$227.00
Will need to bring to tyre shop to do wheel rotation and balancing too.
