when you change the oil should u have to change the oil plug every time. when i had the oil changed at the oil change place they said you have to change the plug every time because of the alumium oil pan
alumium oil pan on 2006 Ford Taurus
It's good practice to change the oil plug gasket when you change the oil. This depends on the specific vehicle design. How much is the item in question? Have you called the Ford dealership and asked them what is included in their oil change for your car?
