T23962—ISO 68 Moly-D Machine Oil, 5 gal. T23963—ISO 32 Moly-D Machine Oil, 5 gal. Moly-D oils are some of the best we've found for maintaining the critical components of machinery because they tend to resist run-off and maintain their lubricity under a variety of conditions—as well as reduce chatter or slip. Buy in bulk and save with 5-gallon quantities.
