4 Answers
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.
Changing your own oil can save you a lot of money and give a great sense of accomplishment! The preparation is simple: just buy the right new oil and filter, plus a wrench and an oil drain pan. Park your car securely, wait for the engine to cool before draining the old oil, locate the drain plug, loosen it, and let the oil flow into the pan. Changing the filter is the most fun part—unscrew the old one, apply a bit of oil to the new filter's gasket, then screw it back on tightly. Once done, pour the new oil into the filler hole, but don't overfill. Check the dipstick, start the engine to ensure no leaks, and you're good to go. Regular maintenance extends engine life and reduces repair costs. The whole process takes about half an hour. For beginners, following a tutorial video is helpful.
Prioritize safety during oil changes: Wear gloves and ensure the engine is cool as the first step to avoid burns or fire. Before draining the old oil, locate the oil pan drain plug and slowly loosen it with a wrench, ensuring the oil flows into a container without polluting the environment. After removing the old oil filter, lightly coat the rubber gasket of the new filter with fresh oil before installing it to prevent leaks. When adding new oil, carefully check the dipstick to reach the standard level, then start the engine for a few minutes to inspect for leaks. Clean up only after confirming everything is normal. Regular oil changes maintain engine health.
