I'm trying to book an oil change with a dealership this weekend. This is gonna be the first time I've ever done an oil change at any dealership 'since i always go to local mechanics.

Are they ever punctual and start/finish as scheduled or can i expect to get out 3 hours later for an oil change? Also is there anything sneaky I might have to watch out for - i heard some ppl posting about the car coming back with and extra couple of miles on the odometer when getting their car serviced.
