Regular maintenance and inspections play a crucial role in prolonging engine life. This practice involves routine checks that help identify potential issues before they develop into significant problems. Regular oil changes, coolant system checks, air filter replacements, and timely servicing according to manufacturers' guidelines ensure that the engine operates smoothly. Maintenance helps maintain optimal performance, enhances fuel efficiency, and minimizes wear on engine components, which collectively contribute to a longer lifespan for the engine.

In contrast, frequent high-speed driving can lead to increased engine stress and wear, while avoiding all engine repairs can allow small problems to escalate into major failures. Running on low-quality fuel can cause improper combustion, leading to deposits that can damage engine components and reduce overall efficiency. Thus, consistent maintenance and inspections are the best recommended practice for ensuring longevity and reliability in engine performance.
