ABSTRACT:
A lubricant filter for internal combustion engines, comprising a cup-shaped member containing one or preferably two cylindrical crown-shaped filter cartridges. The opening of the cup-shaped member is closed by a cover from which a tubular member extends into the inner space of the filter cartridges. A container containing a mixture of additives for the lubricant is accommodated in the tubular member and has at least one opening closed by a diaphragm made of a material soluble in the hot lubricant. The cover has an eccentric inlet opening for the lubricant to be filtered and an axial outlet opening for the filtered lubricant and may further have a second eccentric outlet opening for part of the filtered lubricant.
