What is a characteristic of improper lubrication in an engine?

• A. Enhanced performance
• B. Efficient fuel consumption
• C. Formation of resinous deposits
• D. Improved valve function

Answer: (C)

Improper lubrication in an engine can lead to the formation of resinous deposits, which is a key characteristic of insufficient or inadequate lubrication. When lubrication is not maintained properly, it can result in overheating and excessive wear on engine components. This overheating can cause lubricants to break down chemically, leading to the production of varnishes or resin-like substances that accumulate over time. These deposits can obstruct the flow of oil within the engine, hinder component movement, and ultimately result in engine failure. In contrast, enhanced performance, efficient fuel consumption, and improved valve function are all outcomes typically associated with proper lubrication. Properly maintained lubrication ensures that engine components move smoothly, reducing friction and wear, which in turn promotes effective engine performance and efficient fuel usage.
