Lower your car and locate the oil fill cap on top of the engine. Add the correct amount of new oil, as specified in your owner's manual. Check the oil level with the dipstick and add more oil if needed. Start the engine and let it run for a few minutes, then check for any leaks around the drain plug and oil filter. Finally, reset your oil life indicator if your car has one. Dispose of the old oil and filter properly. Changing your oil is a fundamental maintenance task that you can handle yourself, helping you save money and keeping your Honda Civic ES or ET in top condition. This is an important step in making sure you are taking care of your car properly, and it's something that most owners can accomplish.
