Keeping Your Engine Clean

The key to maintaining engine longevity is simple: frequent oil changes. The oil and filter should be changed regularly for maximum engine performance.

The role of oil in a car's engine is to protect internal parts and provide lubrication against wear. The oil continually circulates throughout the engine, and over time it breaks down. During that time the oil accumulates substances such as dust, metallic shavings, unburned fuel, and even antifreeze that can damage internal engine parts.

The oil filter works to trap and remove debris and other contaminants. When the oil filter becomes saturated, the oil is no longer "cleaned" and the risks posed by contaminants intensify. Oil pressure can also suffer once the filter becomes clogged. As a result, fuel economy decreases and the risk of emissions increases along with the potential for engine failure.

Change your oil and oil filter according to the recommendations in your owner's manual or follow the "every 3 months or 3000 miles" rule of thumb for getting an oil change.
