Check Fluid Levels and Quality

What happens here

Open the engine compartment and check the engine oil dipstick. Observe the oil level, color (new oil may look dark quickly in diesel engines, but burnt smell or metallic sheen is bad), and smell. A burnt smell can indicate overheating or excessive wear. Also, check for leaks around the engine. The video shows that the oil in one machine is already black despite a recent change, which isn't necessarily bad for a diesel but could signal an older, higher-hour engine. You can also inspect the coolant, hydraulic fluid, and fuel for proper levels and contamination. Consistent fluid maintenance is key to long-term reliability in any condition.

Goal: Check engine oil and other fluid levels and quality (color, smell) to assess the machine's maintenance history and potential engine issues.
