Which of the following is NOT a consequence of poor engine maintenance?

• A. Increased engine durability
• B. Higher repair costs
• C. Decreased vehicle reliability
• D. Reduce fuel efficiency

Answer: (A)

The statement regarding increased engine durability is accurate because effective engine maintenance is essential for ensuring that an engine operates efficiently and lasts a long time. Proper maintenance, such as regular oil changes, filter replacements, and timely repairs, helps to prevent wear and tear, reduces the likelihood of major engine failures, and contributes to the overall longevity of the engine.

In contrast, poor engine maintenance typically leads to several negative consequences, such as higher repair costs, decreased vehicle reliability, and reduced fuel efficiency. These issues arise as neglect leads to problems such as buildup in the engine, parts wearing out prematurely, and a decline in performance. Therefore, while good maintenance promotes increased durability, poor maintenance clearly results in the opposite effect, emphasizing why increased engine durability is not a consequence of poor maintenance.
