• oil filter

What is the purpose of a lubricant in a diesel engine?

• To reduce engine performance.

• To improve fuel efficiency.

• To reduce friction and prevent wear and tear.

• To increase friction and promote wear and tear.

What are the signs of a lubrication system problem in a diesel engine?

• Low oil pressure, decreased engine noise, coolant leaks, and increased engine temperature.

• High oil pressure, decreased engine noise, oil leaks, and increased engine temperature.

• Low oil pressure, excessive engine noise, oil leaks, and increased engine temperature.

• High oil pressure, decreased engine noise, coolant leaks, and decreased engine temperature.

How can low oil pressure affect a diesel engine?

• Low oil pressure can lead to increased fuel consumption, decreased fuel efficiency, and increased emissions.

• Low oil pressure can result in excessive engine noise, decreased engine power, and increased engine temperature.

• Low oil pressure can cause oil leaks, decreased lubrication, and increased engine wear.

• Low oil pressure can cause engine damage, reduced performance, and potential engine failure.

What are some preventive maintenance measures for a diesel engine lubrication system?

• Not inspecting for leaks or damage

• Regular oil changes, using high-quality oil and filters, monitoring oil levels and pressure, inspecting for leaks or damage, and ensuring proper cooling and ventilation.

• Using low-quality oil and filters

• Neglecting to monitor oil levels and pressure
