What happens during an engine oil change?

During an engine oil change, the primary objective is to maintain the engine's proper lubrication system, which is critical for its longevity and performance. The correct procedure involves several key steps. First, the old oil is drained from the engine to remove contaminants and breakdown products that accumulate over time. Simply draining the old oil does not address the filtering aspect, which is crucial for optimal performance.

Replacing the oil filter is a vital part of the procedure. The oil filter removes particulates and contaminants from the oil before it circulates through the engine. A clogged or dirty oil filter can lead to reduced oil flow and inadequate lubrication, potentially causing engine damage.

After the old oil is drained and the oil filter is replaced, fresh oil is added to refill the engine’s lubrication system. This fresh oil helps ensure that all moving parts of the engine are properly lubricated, allowing for efficient operation and reducing wear.

In summary, the correct answer encompasses all necessary steps for an engine oil change, promoting better engine health and performance.
