What is a common reason for engine malfunction?

Neglecting proper servicing and maintenance is a common reason for engine malfunction. Regular maintenance tasks, such as oil changes, air filter replacements, and spark plug inspections, help ensure that the engine operates efficiently and can prevent wear and tear that may lead to more significant issues. Over time, dirt, debris, and contaminants can build up in the engine, leading to poor performance or even breakdowns if not addressed. Proper servicing is essential to catch minor issues before they escalate into serious problems that can cause engine failure.

In contrast, using high-quality fuel generally contributes to better engine performance and longevity. Excessive speed use can be detrimental but is often a result of other factors such as operator error or equipment limitations rather than routine malfunction. Short operating hours typically do not lead to engine issues and, in some cases, can keep an engine in better condition since it experiences less wear.
