It takes more like half an hour - write up the ticket. Talk with customer. Move the car. Position the lift. Raise the car. Do the change. Lower the car. Reposition the lift. Move the car. Talk with the customer.Most indy shops have a $100-$120 per hour labor rate. It only takes them 5-6 minutes to do the job?
Even at my best, working with a lift at the hobby shop, it was over half an hour. Check in. Move car, drive on lift. Raise car. Change oil. Drive car off. check out.
