Q

Lube oil contamination will increase due to normal wear of engine components as a result of _________.

🔍 Key Concepts

• Normal engine wear mechanisms in diesel and gasoline engines • How friction and high temperatures affect lubricating oil over time • Different types of contaminants in lube oil (solids, chemical byproducts, corrosion products)

💭 Think About

• When metal surfaces rub together under load and heat, what kinds of byproducts can be created that might get into the lube oil? • Think about both physical particles and chemical reactions: does normal wear produce just one type of contaminant, or several? • Which answer choice best covers the full range of what can reasonably increase in lube oil as an engine ages and parts wear?

✅ Before You Answer

• Be sure you understand that "normal wear" can mean mechanical abrasion and chemical degradation over time. • Ask yourself if each listed contaminant type (abrasive particles, metallic oxides, corrosive acids) can be a realistic result of long‑term engine operation. • Check whether any single option seems to include the others, and whether that broader option fits with how engines typically wear and contaminate their oil.
