Do I need a appointment to have my vehicle serviceed

Oil changes no but other services yes

No appointment necessary if all you need is an oil change.

I tooked my yesterday to service for oil change at 4 pm for my 2015 buick enclave premium took in but oil change still high for 50 buck because i still have recorded to keep there to proof for maintenance record to avoid lifetime warranty's..which i dont like... But. ...that rule.
