Which component is typically checked during an oil change?

The oil filter is a crucial component that is typically checked during an oil change. Its primary purpose is to remove contaminants from the engine oil, preventing them from circulating in the engine. When an oil change is performed, it is standard practice to replace the old oil filter with a new one to ensure that the new oil remains clean and free of debris. This maintenance step helps to prolong the life of the engine and maintain optimal performance.

On the other hand, while brake pads, battery condition, and windshield wipers are all important aspects of vehicle maintenance, they are not directly related to the oil change process. Brake pads are associated with the braking system, the battery's condition pertains to the vehicle's electrical system, and windshield wipers deal with visibility during rain or snow. Thus, these components are typically checked during separate maintenance or inspection services rather than during an oil change.
