Which statement regarding engine maintenance is correct?

Regular oil changes promote engine health is accurate because oil plays a vital role in lubricating the moving parts of an engine, reducing friction, and preventing wear. Over time, oil can become contaminated with dirt, debris, and combustion by-products, which diminishes its effectiveness. Fresh oil ensures that all parts of the engine are well-lubricated, which not only enhances performance but also extends the life of the engine.

Neglecting oil changes can lead to sludge buildup and increased wear on engine components, ultimately resulting in costly repairs or even engine failure. Therefore, adhering to a consistent schedule for oil changes, as recommended by the manufacturer, is crucial for maintaining a healthy engine.

The other statements suggest misconceptions about engine maintenance. New engines still require proper maintenance practices to ensure optimal performance over their lifespan and to prevent issues from developing. Professional help is not always necessary; many maintenance tasks, including oil changes, can be performed by knowledgeable owners. Additionally, while filters are important and should be changed periodically, comprehensive engine maintenance involves more than just changing filters. Regular oil changes are a key component of an effective maintenance routine.
