What is the process for changing car engine oil?

The process for changing car engine oil is: 1. Place an old oil container under the oil pan at the bottom of the vehicle's engine compartment, use a specialized wrench to unscrew the oil filter and remove it; 2. Slowly loosen the oil pan drain plug to drain the old oil, after a period of draining, reinstall the drain plug; 3. After completely draining, tighten the screw (not too tight), then pour new oil into the engine and screw on the oil filter. After adding oil, remember to check the oil dipstick. Engine oil serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine, earning it the reputation as the 'blood' of the car.
Here's how I change the engine oil: First, let the engine warm up for about 3-5 minutes before turning it off. While it's still warm, crawl under the car to locate the oil pan drain plug. Remember to place a large bucket underneath to catch the oil before loosening it. Once most of the dark old oil has drained out, unscrew the oil filter. Before installing the new filter, apply a bit of fresh oil on the rubber gasket, then hand-tighten it – no need to overtighten with tools. Finally, pour fresh oil through the engine hood filler until it reaches slightly above the midpoint on the dipstick. Don't forget to start the engine and let it run for two minutes to check for leaks, then turn it off and wait a few minutes before checking the dipstick again and topping up if necessary. Never dispose of used oil improperly; take it to a repair shop for recycling – that's the most reliable method.
