🔍 Key Concepts

• Meaning of neutralization number in lube oil testing (acid/base content) • What a precipitation number indicates about contaminants and insolubles in oil • Why color and small changes in flash point may or may not be reliable criteria for condemning oil

💭 Think About

• Which of these test results directly reflects the amount of solid contaminants, sludge, or oxidation products in the oil? • Is dark or black color alone a reliable reason to discard engine lube oil in a diesel engine? Why or why not? • Among the listed indicators, which one would most suggest that the oil can no longer properly lubricate and keep contaminants in suspension?

✅ Before You Answer

• Verify which test is specifically designed to show insoluble contaminants / sludge level in the oil. • Consider whether a low neutralization number usually means the oil is worn out or still has reserve alkalinity. • Ask yourself if marine diesel oils often turn black in normal service, and whether that alone is a discard criterion.
