<human>:  How do I change the oil in my car's engine?
<bot>: To change the oil in your car's engine, you will need a few supplies. First, you will need a new oil filter and oil, which you can buy from your local auto parts store. Next, you will need a few tools, like a wrench, a drain pan, and an oil filter wrench. Make sure to always wear protective goggles and gloves to avoid any potential messes. Now, raise the car up on either a lift or a jack so that you can access under the engine. First, locate the oil plug and remove it. Then, allow the oil to drain into the pan until all of the old oil is gone. Next, locate the oil filter and unscrew it from the engine. Once the old filter is removed, replace it with the new one. Then, replace the oil plug and refill the engine with the oil. Finally, turn the engine over a few times and check for any leaks. If all is in order, you have successfully changed the oil in your car's engine.
