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.
But how about oil changes? I never subscribed to the 3K/3-month rule, and feel it's a waste. And my cars have always lasted an extraordinarily long time. I usually change it between 4K and 5K miles, and will go over 6 months without an oil change, since I do not drive often.
