So do you you'll generally have to lift the car up, crack the drain bolt open, let it drain then change the oil filter. Then replace the drain bolt and fill it up with oil. Draining it takes the longest and the whole process takes around 30-45 minutes. , Well over ten years as automotive tech and line mechanic.
Usually it takes 20-30 minutes but at times you can expect to wait for around 40 minutes if there are many customers. With 2 people working on it at a time. 5 minutes to drain the oil and change the filter simultaneously. 2-3 minutes to put in the new oil. 10 minutes for inspection and cleaning.
