🔍 Key Concepts

• Viscosity and how thick or thin oil affects lubrication films between moving metal parts • Differences between flash point, pour point, and TBN (Total Base Number) in lube oil properties • How lubrication quality impacts friction, wear, and oil consumption in diesel engines

💭 Think About

• Which oil property most directly controls the thickness and strength of the oil film separating moving parts? • Which listed properties mainly relate to temperature behavior or chemical neutrality rather than mechanical friction? • If an oil is too thin or too thick for engine clearances, what happens to metal-to-metal contact and oil burning/consumption?

✅ Before You Answer

• Match the property that governs oil film thickness under operating conditions with friction and wear • Eliminate properties that are primarily about temperature limits (ignition or flow) rather than lubrication performance • Confirm that the remaining property directly influences oil consumption through leakage and burning in the cylinders
