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.
From the personal experience of having had to change oil on a number of different vehicles over the years, fifteen minutes for a quickie, engine warm, and filter isnât jammed on. On the other end, it may wind up taking an hour or more, inaccessible filter that was cranked down way too tight, engine stone cold so oil takes forever to drain down.
