Tungsten disulfide or WS2

Hi,

Iam searching ways to reduce friction and my race mate suggested to try this WS2. They use it in their Formula 3 race cars in all bearings and gears. Effect can be seen immediately when you apply it if you two new bearings and you put it on the other.

I will try this in my Lupo, but where is still unknown. It can be mixed even to oil but I am trying to find more data on that from the internet. Here they say can be mixed to oil. My friend said if you put too much you engine will blow so gotta be careful not to put too much. Thats why I want more data. If you can help to find more data would help a lot. Specially to the oil mixing case.

Lower Friction

"Pur-Tungsten Powder can be mixed with synthetic oil at a ratio of about 1% or about 1 tablespoon per 5 quarts oil. Our results show the mixed protective film makes the tungsten disulfide motor oil display excellent antiwear, antifriction and extreme pressure properties, and this kind of motor oil can reduce the exhaust emission and oil wastage, enhance the fuel economy and improve the environment, so it is a kind of environment-protective and energy-saving motor oil."
