How to Change Engine Oil for a Car?

[DelElliott]

To change the engine oil for a car, follow these steps: 1. Wait for the engine temperature to drop, 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; 3. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; 4. Use a specialized wrench to remove the oil filter, apply oil to the new oil filter's gasket, and tighten it clockwise by hand; 5. Add the new engine oil through the oil filler cap on the engine valve cover, typically filling about three-quarters of the oil container. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers.
