I would use standard motor oil before STP. It only takes enough to wet a q tip. Heat the mold up. (Make sure to degrease teh mold well before using it. I boiled mine in soapy water for a few minutes before rinsing with clean water. I then let it dry well.) Lube the contact points. Your mold should have a picture showing where to put the lube. Also lube the bottom of the sprue plate. It helps a lot.
