Question 1 of 27070

An additive used to improve the ability of a lube oil to reduce friction in hypoid gear applications is known as a/an __________.

🔍 Key Concepts

• Hypoid gears operate under very high sliding and pressure conditions at the gear tooth surfaces • Different lube oil additives have specific purposes: dispersants, viscosity improvers, detergents, and those for high-load surfaces • Additives designed for very high loads and boundary lubrication are different from those that only change thickness or cleanliness of oil

💭 Think About

• Which additive type is specifically designed to protect metal surfaces when the oil film is squeezed very thin under very high pressure? • Which options are mainly about keeping contaminants in suspension or changing how thick the oil is with temperature, rather than handling heavy sliding loads? • In hypoid gears, do you expect gentle rolling contact or heavy sliding and scuffing at the tooth contact areas?

✅ Before You Answer

• Identify which option is associated with high-load, high-pressure tooth contact protection • Eliminate any additive types that mainly deal with cleanliness or keeping particles suspended • Eliminate any additive type that is primarily used to change viscosity vs. temperature rather than to protect against metal-to-metal contact
