Schaeffer's Moly Ultra Grease NLGI #2 is an aluminum complex, good all-purpose, waterproof grease formulated for heavy-duty automotive, construction, mining, farming and industrial equipment. Schaeffer's Moly Ultra EP Grease quickly lubricates metal surfaces, offering solid, durable protection that lasts longer than conventional greases. Even during periods of excessive pressure, increased heat and high shock loads, this extreme pressure grease resists breaking down. Fortified with Moly for extra protection, Moly Ultra EP significantly reduces friction, which reduces wear and contact area temperature. Can also be used on electric motor applications.
