Drain Old Engine Oil

What happens here

Position a waste oil bucket directly beneath the engine's drain plug. Carefully remove the drain plug, allowing the old engine oil to drain completely. Observe the color and consistency of the oil; black oil is expected, but check for any metal shavings, which could indicate internal engine wear. Once drained, reinstall and tighten the drain plug.

Goal: Remove old, potentially degraded engine oil from the excavator.
