Draining old engine oil in 11 steps

Drain old, used engine oil only when the engine is warm. If the engine is not hot enough, some of the cold oil may remain on the engine wall and in the oil pan. This is definitely worth avoiding because by mixing old, used and fresh engine oil, the newly poured oil can lose a lot of its original chemical properties.

Steps for draining engine oil

  1. Place the drain can under the sump drain plug.
  2. Open it, but do not remove the oil filler cap.
  3. Failure to do so will cause the oil leaking from the engine to cause a vacuum in the engine. Old oil may flow more slowly and some of it may remain inside the engine.
  4. If the filler cap does not remain stable on top of the engine after opening, remove the cap and cover the oil filler with a clean cloth.This will prevent dirt from entering the engine through the opening.
  5. Unscrew the sump drain plug and remove it. Flowing engine oil can be extremely hot, Please always wear heat resistant work gloves to avoid burns. Most of the oil usually drains within a few minutes.
  6. Surround the oil filter with a clean cloth. This is necessary because it is likely that there is engine oil in the filter as well, so if we open it, it will definitely flow outwards.
  7. Loosen the oil filter with oil filter pliers.
  8. Pour the oil in the oil filter into the drain can.
  9. Clean the area around the oil filter. Make sure the oil filter’s rubber seal and the engine block where it meets the rubber seal are clean, otherwise the new oil filter’s seal will not seal perfectly.
  10. If you have time, let the remaining oil drip out.
  11. After half an hour, move the car a little to get the tired oil out of the “hidden” parts of the engine.
    Only when the car is on the ground, of course.

My own experience is that even after an hour and a half, the oil still drips, albeit slowly. That’s why I take at least two hours to drain used oil.
