  • Once the oil has drained, replace the drain plug and tighten it securely.

  • Locate the oil filter, typically accessible from the top or side of the engine, and remove it using an oil filter wrench.

  • Apply a thin coat of new oil to the gasket of the new oil filter and screw it on until it's snug.
