ABSTRACT:
An oil filter for an internal combustion engine lubrication system has an anti-drainback valve that is temporarily held open with a quantity of special grease during the initial filling of the engine's oil lubrication system with oil, and then passively melts or dissipates upon contact with the oil so as to allow the anti-drainback valve to thereafter close.
