Q

What is the BEST indication that a diesel engine full-flow lubricating oil filter must be serviced?

🔍 Key Concepts

• Full-flow lubricating oil filter function in a diesel engine • Relationship between filter clogging and pressure drop across the filter • Effect of filter condition on pump discharge pressure vs. manifold (downstream) pressure

💭 Think About

• If a full-flow filter starts to plug, what happens to the pressure on the inlet side of the filter compared to the outlet side? • Which gauge or reading would change FIRST and most clearly tell you that the filter itself (not the pump) is the problem? • How would a clean filter vs. a dirty filter affect the pressure difference across the filter element?

✅ Before You Answer

• Verify how pressure drop across a filter is defined (which side minus which side). • Think about which condition indicates the filter is restricting flow, not just that system pressure is low for any reason. • Check which choice points directly to a change in differential pressure across the filter, rather than a general system pressure change.
