🔍 Key Concepts

• Oil viscosity vs. temperature in engine lubrication systems • Relationship between engine speed/load and lube oil pressure • Effect of fuel dilution in lube oil on pressure and viscosity

💭 Think About

• How does oil temperature affect its thickness (viscosity), and how does that thickness influence pressure in the lube oil system? • At what combination of speed and temperature is the oil likely to be the thickest while still at normal operating conditions? • Would adding fuel to the lube oil make it thicker or thinner, and how would that change pressure readings?

✅ Before You Answer

• Compare which choice gives the coolest oil at a normal operating condition • Decide which options would make the oil thinner and reduce pressure rather than increase it • Confirm that extreme conditions (like high temperature or high fuel dilution) typically lead to lower viscosity and lower pressure
