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.
TOM: Or just change the oil when the engine is cold. You'll have to wait a little longer for it to drain if you want to get most of the oil out. And a small amount will be left behind. But you'll still get 98 percent of the benefit of the oil change. And you'll be able to keep all of your arm hair.
