Parts Desk Insights: Always replace the drain screw gasket on every oil change — reusing a compressed gasket is a leading cause of slow oil seeps at the drain plug. If you need a single-use or smaller quantity option, see the Sierra Oil Drain Screw Gasket 47-4698 (single). For a complete oil change solution, consider pairing with a Sierra Oil Change Kit. Verify fitment against your engine's service manual before ordering.
