Regular service parts encompass consumable items required for preventative maintenance to ensure optimal vehicle function. These components include fluids like engine oil, coolant, brake fluid, and transmission fluid, alongside filters such as oil, air, cabin, and fuel filters. Spark plugs, belts, and hoses are also included, addressing critical engine and drivetrain systems. Technical specifications center on fluid viscosity/type, filter micron ratings, and material composition for durability and compatibility. Replacement intervals are dictated by manufacturer recommendations based on mileage or time, maintaining warranty compliance and preventing component failure.
