🔍 Key Concepts

• Viscosity and what happens to it when a liquid is heated or thinned • How fuel dilution affects lubricating oil properties in diesel engines • Difference between changing flow rate and actually changing the oil’s chemical/physical composition

💭 Think About

• Which option would actually CHANGE the oil’s thickness, not just its temperature or circulation rate? • In real engine casualties, what contamination do engineers worry about when lube oil starts to get too thin? • Does adding a heavier grade oil (like SAE 70) make the mixture thicker or thinner overall?

✅ Before You Answer

• Identify which choice directly thins or dilutes the oil, instead of only cooling or circulating it • Think about which condition is a known engine casualty that raises concern for bearing damage due to low viscosity • Eliminate any option that would logically make the oil more viscous (thicker) rather than less
