The steps for changing engine oil are as follows: 1. After driving the car onto the lift, turn off the engine, use the lift to raise the vehicle, engage the handbrake, and secure the front wheels with wooden wedges; 2. Place an old oil container under the oil pan, locate the oil pan drain bolt, and slowly loosen the drain bolt, being careful not to come into contact with the hot oil; 3. Move the oil container under the oil filter, use an oil filter wrench to loosen the filter, then unscrew it by hand. If the filter is still hot, remember to wear gloves; 4. Refer to the user manual to select the appropriate oil filter; 5. Apply new oil to the gasket of the new filter. If the filter is installed vertically, you can pour some new oil into the filter to reduce dry friction during the next engine start; 6. Pour the new oil into the oil pan, following the instructions in the user manual. Use a funnel to prevent spilling oil on the outside of the engine.
Every time I change the car oil myself, I follow the standard procedure to ensure safety and effectiveness. Before starting the whole process, the car must be parked and turned off, with the handbrake pulled tight to prevent sliding. Prepare tools including a jack or ramps to lift the car body, and wear thick gloves to prevent burns. Locate the drain plug under the chassis, slowly loosen it with a wrench to let the old oil flow into the oil pan, being careful not to splash the hot oil on yourself. After the oil has drained, remove the old oil filter, apply new oil to the seal of the new filter, and tighten it to prevent leaks. Clean the drain hole surface and tighten the bolt, then pour in the new oil using a funnel to avoid spills. While pouring, check the dipstick to ensure the oil level is between the middle marks and does not exceed the upper limit. Start the engine and run it for five minutes to check for leaks underneath. Dispose of the used oil at a repair shop for environmentally friendly recycling. It is recommended to change the oil every 5,000 kilometers to keep the engine clean and extend its lifespan. The whole process takes about an hour but can save a lot on maintenance costs and also teach you some skills.
