It's preferable to call and one in order to be shown about the time you're dedicate on them...
Not required but you may be putting in an active queue and them it's 50/50 on your wait time - could be shorter or longer depending on the day. Mid to later in a week maybe better for a walk in
I heard that it is not required
I have always made an appointment for my inspections at Wagner. Im not 100% if it is required though.
Do I need appointments for oil change?
