I want to change the oil in my car.

It is generally a good idea to have the oil in your car changed every few thousand miles, or every six months, in order to ensure optimal performance. However, checking your car's owner's manual is the best way to confirm how often oil changes are necessary. Generally, most cars should have their oil changed every 3,000 miles, although some vehicles need more frequent oil changes, and some can go 5,000 miles or more between oil changes. If it has been awhile since your last oil change, or you are unsure how often yours needs to be done, consider having a qualified mechanic check it for you. They should be able to check the current condition of your oil and advise you on the best course of action for your specific car.
