Your Mazda 5's combustion process is the main process of what makes your car drive. The Oil Separator helps decrease the amount of oil lost during the combustion process. It helps separate the oil from the vapor released from the crankcase that goes towards the combustion process. The vapor that is released contains trace amounts of oil, fuel and water. The oil separator helps separate the oil, and it helps prevent any damage to internal engine parts.
