Review on Pack of 20 Prime Ave Oil Drain Plug Washer Gaskets for Mazda Part# 9956-41-400 - Compatible and Sealed by Billy Stull

These connectors work well and fit well. I can't trust oil change shops anymore because these washers are never replaced or thrown away. I started changing my oil to maximize service quality. If you don't want to change the oil yourself, you can at least buy one and request an oil change place to use it after you put the drain plug back in place.
