<human>:  Can you walk me through how to change my car oil at home?
<bot>: First, you will need to determine what type and weight of oil your car requires. The owner's manual should provide the specifications. You will then need a few tools, such as an oil filter wrench, an oil drain pan, an oil filter, and an oil pump. Once you have gathered the necessary materials, you can begin. Start by parking the car on a level surface and engaging the parking brake. Locate the oil fill/dipstick and unscrew it. Place a drain pan beneath the engine and find the oil drain plug. Unscrew the plug and allow the oil to drain completely. Replace the plug when finished and secure it with the wrench. Next, take out the oil filter and replace it with a new one. Re-attach the oil fill/dipstick and unscrew it to create a vacuum. Finally, slowly pour in the new oil, reference the owner's manual for the recommended amount. Once finished, replace the dipstick and start the engine to check for any oil leaks.
