I have seen a lot of videos and discussions about Seafoam on Cooper S but would it work as well on a base or is it even necessary? How do you properly use that liquid on the base engine? Just dump 1/3 on the gas, 1/3 on the oil and 1/3 on the vacuum line which by the one I want to confirm if it is this one....


I think this picture from Pelicanparts is showing a Cooper S.
