What Should Be Noted When Changing Engine Oil for a Car?
2 Answers
When changing engine oil for a car, the following points should be noted: 1. Choose the appropriate engine oil for the vehicle; 2. Perform the oil change as much as possible when the engine is warm to ensure complete drainage of the old oil; 3. The oil filter must be replaced when changing the oil; 4. The amount of oil added should be appropriate, as indicated by the oil dipstick; 5. After adding the oil, start the engine and check all components for any leakage. Engine oil, also known as engine lubricant, serves the following functions: 1. Lubrication and friction reduction; 2. Auxiliary cooling; 3. Sealing and leak prevention; 4. Rust and corrosion prevention; 5. Shock absorption and cushioning. Engine oil consists of two main components: base oil and additives, with the base oil being the primary constituent of the lubricant.
I've been driving for almost twenty years, and changing engine oil is something I never take lightly. First, you must choose the right oil grade—check the vehicle manual for the recommended viscosity, and don't guess or use the wrong oil. The oil temperature should be moderate; let the engine warm up a bit but not too hot before draining the old oil. When changing the oil, replace the oil filter as well, and apply a bit of oil to the new filter's seal to prevent leaks. Don't pour all the new oil at once; leave some space, start the engine and let it run for a minute, then check the dipstick and top up to the middle mark. Proper disposal of old oil is crucial—I store it in a container and take it to a waste oil recycling point to avoid polluting the environment. Change the oil regularly every 5,000 kilometers or six months, and don't slack off—this keeps the engine running smoothly and lasting longer. For safety, wear gloves and goggles to avoid oil splashing on your skin. Finally, check the ground for any oil leaks and note the maintenance time.
