Depends on the stealership and how many miles you drive.
I have a good place that changes my oil and filter, vacuums the car, checks the tranny, diff, tires and cleans the windows, while I watch. They then show my the oil level after, and I can see them put in the good oil I paid for. I'm outta there in 15 minutes TOPS for $70 Mobil One oil change 6 quarts.
That said, the service advisors at my dealership know less about my car than a 6 year old child. It takes me 15-30 minutes just to get my car checked in there. They are total ass clowns. They touched my car once and that was the last time, unless I have a warranty claim. Idiots.
From my cold dead hands......
