    • If the oil level is low, add the recommended oil type (check the owner’s manual).
    • Run the engine and check the oil level again, topping off as necessary.

  2. Oil Change

    • If the oil is dirty or old, perform an oil change.
    • Tools Required: Oil filter wrench, socket set, oil catch pan, funnel, new oil, new oil filter.
    • Instructions:

      • Place the oil catch pan under the oil pan and remove the drain plug to let the old oil drain out.
      • Replace the oil filter using the oil filter wrench.
      • Install a new drain plug and torque it to specification.
