When fuel burns to be converted into the energy that runs your engine, there are chemical byproducts from that process. These byproducts greatly resemble ash and stick to the walls of your engine’s cylinders. So, when oil circulates through these areas, it picks up that ash and ends up deposited on your oil filter. This is the primary cause of dirty oil.
