2. Change Engine Oil

  1. Drain the Old Oil:

    • Install the new oil filter by hand until snug, then tighten slightly more with the wrench.

    • Replace the drain plug and torque to manufacturer specifications (typically 20-25 ft-lbs).
    • Pour the recommended type and amount of new engine oil (typically 0W-20 for Honda Accord) into the engine via the oil filler cap.
