I use this stuff below on my Edison Big Gears and Mainsprings....It's also excellent on Victor and Columbia Disc Machines as well which I rarely work on.. It is Castrol GTX Brown Bearing Grease in a Tub... Sold at any Wal-Mart...or any Autoparts store.. Been using it for years with very high success.. Everything else gets Sewing Machine oil....especially on small gears..
