Replacing engine oil involves the following steps: 1. Use a jack to lift the vehicle, locate the drain plug and loosen it to drain the oil. 2. Unscrew the oil filter and place a container beneath it. 3. Install a new oil filter and add fresh engine oil. The functions of engine oil are as follows: 1. Lubrication: Maintains smooth operation between cylinders and pistons, reducing friction and wear between components. 2. Cooling: Assists the cooling system in lowering the temperature of the engine's internal environment. 3. Cleaning: Removes sludge, carbon deposits, and other impurities from engine parts. 4. Sealing: Seals gases within the engine pistons and piston rings, minimizing the ingress of external contaminants.
When it comes to changing car engine oil, I think it's great for experienced drivers to share their tips. First, wait until the engine is completely cool to avoid burning your hands. Then, prepare the necessary items: a new bottle of engine oil, a new oil filter, a wrench, an oil drain pan, and park the car on level ground. Lift the car or use a jack to safely support it, locate the drain plug on the oil pan, loosen it with the wrench, and let all the old oil flow into the drain pan—avoid making a mess. Next, remove the old oil filter. Before installing the new filter, apply a bit of new oil to its rubber gasket, then tighten it properly for a good seal. Reinstall the drain plug, tightening it firmly but not excessively. Finally, pour the new oil into the engine from the top, filling it up to the marked level. Start the engine to check for any leaks, and remember to clean up properly—dispose of the old oil through eco-friendly recycling. Doing it yourself saves money and helps maintain an older car. Change the oil every 5,000 kilometers to ensure smooth engine performance.
