Bought my new ride to the casa for its first 1,000 KM check-up. The Service Advisor gave me a list of things that they were gonna do like tune-up, change of oil, etc.

Is an oil change really necessary even if the car is new and was only driven for 1thou KM? Also, how would I know if the casa really did changed the oil since they don't allow customers in the service bay area? I felt robbed when the bill came out asking me to pay P2,900++

I'm a first time car owner so I'm not familiar with the service maintenance process. I appreciate all your input. Thanks!
