This lack of lubrication leads to increased friction between moving parts, causing accelerated wear and tear on the engine over time. As a result, the engine's overall efficiency decreases, and it may start consuming more fuel than usual.

One of the primary reasons for this is the presence of contaminants such as dirt, water, and other foreign particles. These contaminants can enter the oil system through various means, including improper maintenance, aging seals, or even the combustion process. When the oil becomes contaminated, it can no longer effectively suspend these particles, leading to increased wear on engine components like the pistons, valves, and cylinder walls.

The increased friction and wear caused by contaminated oil result in higher energy losses within the engine. This energy loss manifests as increased heat generation and reduced efficiency in the combustion process. As a consequence, the engine requires more fuel to achieve the same level of performance, leading to higher fuel consumption. Over time, this can significantly impact your vehicle's fuel economy, often resulting in noticeable increases in fuel usage.

Regular oil changes and proper maintenance are crucial to preventing engine contamination. By ensuring that your oil is clean and free of contaminants, you can maintain optimal engine performance and fuel efficiency.
