WS2 Powder - Tungstan DiSulfide

[WhyMe]

Have any of the engine builders or performance shop guy's heard of this? A friend saw my new 2SS today and told me about it. He has a 2003 Chevy HD pick up and the shop where all of his work is done told him about it several years ago. They told him to add 1/2 ounce to his oil for the next 5 oil changes. His fuel mileage went from 12.7mpg to 14.2mpg. It's a type of powder with Nano particles that adhere to any metal surface that rubs against another metal surface. Before adding it based on their word he researched the product including reading many college research papers that all backed up the shops statements. He said an easy way to think of it was to slide on a wood floor in your socks, pretty slippery but then throw a couple of decks of playing cards on the floor and slide again. Much slippery as the friction is reduced. He started using it at 45k miles and now has over 100k miles. Also uses it in the rear end as well as the radiator to lube the water pump. They recommended it for the manual transmission but against using it in the auto.
