Oil Analysis and Acid/Base Numbers

The video tutorial explains the significance of acid and base numbers in oil analysis, highlighting their role in preventing corrosion and optimizing oil change intervals. It covers the formation of corrosive acids and the neutralizing effect of base numbers, along with testing methods like titration. The tutorial also addresses the impact of high acid/base numbers, varnish formation, and corrective actions to maintain machinery efficiency.

What is one of the industry-specific terms used for base numbers?

• Neutralization Number

• Reserve Alkalinity

• Acid Value

• Total Acid Number

Why is it important to measure the acid number of a lubricant?

• To calculate the oil's density

• To assess the oxidation level and prevent corrosion

• To determine the color of the oil

• To measure the viscosity of the oil

What is the purpose of a base number in lubricants?

• To enhance the oil's color

• To neutralize acids formed during combustion

• To reduce the oil's density

• To increase the oil's viscosity

What is a potential side effect of having too high a base number in oil?

• Increased oil viscosity

• Formation of ash leading to engine issues

• Reduced oil density

• Decreased oil color

How is the acid number measured in oil analysis?

• By using a thermometer

• By measuring the oil's density

• By titration with an alkali

• By checking the oil's color

What is the significance of potentiometric titration in oil analysis?

• It assesses the oil's viscosity

• It uses voltage change to determine acid number

• It calculates the oil's density

• It measures the oil's temperature

What can cause a high acid number in oil?

• Low oil viscosity

• High oil density

• Overheating or overuse of lubricant

• Low oil temperature

What is a common problem associated with high acid numbers in large systems?
