Is the car clean after changing the oil?
1 Answers
After changing the oil, the car becomes relatively clean. Engine oil is extremely important for the engine, as it serves the functions of lubrication, heat dissipation, cleaning, and sealing within the engine. Engine oil can be considered the lifeblood of the engine. If the engine oil is not changed for a long time, its lubricating performance will degrade, leading to abnormal wear and tear on the engine. The method for changing car engine oil is as follows: 1. Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. 2. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Then, start the engine for about 30 seconds to allow the oil in the main oil passage to drain out. 3. Use a special wrench to remove the oil filter; apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand. 4. Add the new engine oil through the oil filler cap on the engine valve cover, typically filling about three-quarters of the oil container. 5. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. 6. After stopping the engine, pull out the oil dipstick to ensure the engine oil level is within the standard range.
