Abstract
A reusable oil filter adapted to filter oil used in an engine includes a housing operatively connected to the engine, filter media disposed within the housing, a singular backwashing inlet operatively connected on the housing and an oil drain operatively connected with the housing. Pressurized air delivered through the backwashing inlet forces filtered oil to backflow through the filter media displacing contaminated oil from the filter media and creates an air-oil foam for further cleaning the filter media while the housing remains connected to the engine.
