Hi.
I was sold on Molybdenum Disulphide nigh on 30 years ago. Working for what was then a publicly owned electricity supply and distribution system.
The CEGB ( Central Electricity Generation Board ) were decommissioning many of the smaller lower efficiency power stations, as a consequence they chose a turbine and alternator to destruction test lubricants. Raw MS was administered to the main bearings and then run, under load, without the usual flow of oil through the bearing boxes. Believe it or not the set lasted 8 hours before the Bronzes picked up and total destruction followed.
A single application had coated the surfaces sufficiently to make a long lived near frictionless environment.
I've been using MS 3 grease for just about everything since.
Cheers Graham.
