One key element is understanding how to properly hot drain an oil filter. According to the Filter Manufacturers Council, you should remove the filter from the engine while warm, then immediately drain the free-flowing oil. Next, puncture the filter dome and invert the filter to drain into the appropriate container at a temperature above 60° F for at least 12 hours.
Sage Oil Vac offers a product that can simplify draining of filters. The Filter Stinger is used to pierce a used oil filter, then vacuum out the oil. "The Filter Stinger and the Used Filter Receptacle cut down on many spills, because the used oil is vacuumed from the filter before it is spun off," Sage explains. This also decreases the burn hazards to the technicians, since they are not handling the hot oil.
