How do you change the oil on a car?
assistant
The first step to changing the oil on a car is to warm up the engine by running it for a few minutes. Then, place a container beneath the drain plug and remove the plug under the engine with a wrench. Allow the oil to drain completely and then reinstall the drain plug. Next, remove the oil filter using the appropriate socket wrench and discard it. Replace it with a new filter and fill the engine with the recommended grade of oil. Finally, check the oil level with the dipstick and make any necessary adjustments.
