Which factors can degrade engine performance over time?

Neglecting maintenance and using inferior fuel are significant factors that can degrade engine performance over time. Regular maintenance is crucial for ensuring that all components of the engine work efficiently. This includes changing the oil regularly, replacing air and fuel filters, and checking ignition components. Neglecting these maintenance tasks can lead to the buildup of sludge, decreased lubrication, and eventually, engine wear or failure.

Using inferior fuel can cause problems as well; lower-quality fuels may contain contaminants or additives that can lead to carbon buildup in the combustion chamber and on fuel injectors, negatively affecting combustion efficiency and power output. Overall, maintaining the engine and using the right fuel type are vital to preserving performance and longevity.
