I oil! I greased a screw drive once and when the temperature got real
cold, even in the garage, the opener would not function properly. Not
knowing what to do, I had called in a repairman. He said never to use
grease. I even oil the torsion springs. The even make a special spray
oil for the rollers, chains, etc. The repainman gave me a can.
