If the engine oil is used in the BEAR Power Unit is is 15W-40 then it would get drained and refilled during which scheduled inspection

• A. 400 hour
• B. 100 hour
• C. 800 hour
• D. 2000 hour

Answer: (A)

Regular engine oil changes are scheduled at a specific inspection so lubrication stays effective and contaminants don’t build up. For the BEAR Power Unit using 15W-40 oil, the drain-and-refill is done at the maintenance interval designated for that oil grade, which is the middle-range inspection in the given schedule. This keeps wear protection solid without adding unnecessary downtime, and it avoids oil degradation that could occur if the interval were too long. In short, the oil change occurs at the standard mid-range inspection. For the exact hour value, refer to the BEAR Power Unit maintenance manual.
