1 Answers
Car engine oil should generally be changed approximately every 6 months. Engine oil, also known as engine lubricant, serves the following functions: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and removing contaminants; 4. Dampening vibrations and cushioning impacts; 5. Preventing rust and corrosion. The steps for changing car engine oil are as follows: 1. Start the vehicle's engine to warm it up; 2. Unscrew the oil drain bolt; 3. Remove the oil filter; 4. Apply new oil to the gasket of the new oil filter; 5. Pour the new oil into the oil pan; 6. Check for leaks under the engine and verify the oil level using the dipstick before starting the engine for testing. Engine oil consists of base oil and additives. The base oil is the primary component of lubricating oil, determining its fundamental properties, while additives compensate for and enhance any shortcomings in the base oil's performance.
