Q

Which of the following conditions can cause excessive lube oil consumption in a diesel engine?

🔍 Key Concepts

• Relationship between lube oil temperature and oil viscosity (thickness) • How lube oil pressure and flow affect bearing protection vs. oil burning • What a dirty lube oil strainer usually causes in a system

💭 Think About

• Think about which condition is most likely to make oil thin enough to pass piston rings and valve guides and get burned in the cylinders. • Ask yourself: which condition tends to reduce oil FLOW, and which tends to change how easily oil can leak past clearances? • Consider what happens to oil behavior when it is too cold versus when it is too hot inside a running diesel engine.

✅ Before You Answer

• Identify which option would most likely reduce oil viscosity and make it easier for oil to be carried into the combustion space. • Eliminate any options that would mainly cause starvation or restriction rather than increased consumption. • Confirm in your mind what a dirty lube oil strainer does to pressure and flow in the system.
