What are the steps for changing engine oil and oil filter?

[DelMariana]

The steps for changing engine oil and oil filter are: 1. Remove the drain plug and drain the engine oil; 2. After draining, clean the drain plug; 3. Install and tighten the drain plug; 4. Loosen the oil filter with an oil filter wrench; 5. Apply engine oil to the O-ring of the new oil filter; 6. Hand-tighten the new oil filter onto the oil filter bracket; 7. Use the oil filter wrench to tighten the filter an additional three-quarters of a turn. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives compensate for and improve the deficiencies of the base oil.

Changing the oil and filter is something I often do myself, and I find it quite simple. Drive the car for a few minutes to warm up the engine so the oil flows more smoothly. Park the car on level ground, engage the handbrake, and ensure safety. Place the oil drain pan under the chassis, locate the drain plug, loosen it with a wrench, and the old oil will flow out. Wait until the oil has completely drained, then wipe the drain plug opening clean with a towel and tighten it. Next, handle the filter—use a tool to remove the old one, make sure the new one is the correct model when purchasing, apply some new oil to lubricate the seal, and hand-tighten it. Finally, pour in the new oil slowly, being careful not to overfill, and use the dipstick to check that the oil level is within the middle range. Start the engine for a few minutes and check for leaks around the drain plug and filter. Remember to dispose of the old oil at a recycling point to avoid environmental pollution. Regular maintenance keeps the car running smoothly.

The first time I changed the oil, I was a bit flustered, but I managed to complete it step by step. Start the vehicle for five minutes to warm up the oil, then park it on level ground. Prepare the tools: a wrench, new oil and filter, and a drain pan. Crawl under the car to locate the drain plug, slowly loosen it with the wrench, and let all the old oil flow into the pan. Once the oil stops, tighten the plug back. Next, replace the filter, which is usually located near the engine. Use a tool to twist off the old one counterclockwise, clean the interface, apply some oil to the new filter's seal to prevent leaks, and hand-tighten it clockwise without overdoing it. Pour in the new oil from the top of the engine in batches, checking the level with the dipstick after each liter to avoid overflow. Once done, start the engine and let it run, then turn it off and check the fluid level again to ensure everything is normal. The process isn't difficult, and regular maintenance can extend the engine's lifespan.

The oil change process must prioritize safety, and I'll emphasize the key points. The oil is too hot right after the engine is turned off, so wait ten minutes before starting. Wear anti-slip gloves to protect your skin. Park the vehicle on a hard surface and ensure the jack provides reliable support to prevent slipping. Avoid splashing old oil when opening the drain plug, and make sure all oil is drained before tightening. When replacing the filter, confirm the correct orientation and apply a small amount of oil to reduce friction. Add new oil according to the manual's specified quantity, as too much or too little can damage the engine. Finally, start the engine to check for leaks, and seek professional help if in doubt. Dispose of waste safely to avoid environmental pollution. Regular maintenance ensures reliable vehicle operation.

Changing the oil yourself is much cheaper than going to a shop, saving hundreds each time. Spend a little on tools initially, then reuse them for future changes. Warm up the engine by driving for a few minutes before parking. Loosen the drain plug with a wrench, let the oil drain completely, then tighten it back. When replacing the filter, compare the old and new ones to avoid incorrect installation, and apply oil to the seal for a tighter fit. Pour in the new oil according to the manual's specified amount, and buy high-quality brands to extend the interval between changes. Check for leaks, and you're done. Compared to professional service, DIY oil changes take only half an hour, saving money and hassle. Regular changes can prevent issues like carbon buildup.
