Tungsten Disulfide

[S4-Casa]

Anybody know about this stuff?

Tungsten Disulfide... its a dry lubricant and can be bonded to any metal material. It places a coat on anything on the motor -
I heard there was a vid out there that has a bare block Not coated but everything else was coated ie pistons rods crank blah.. and made another 90 hp at the wheels.
As I look at this... lets say the motor will get 0 HP difference, but provides protection up to 1000 degrees... would this help the chra and journals.
I am thinking about the oil being the suspension for the journals and the tungsten disulfide as the heat lubricant. Now its a dry lubricant, so there is no need for external oiling. Its nano technology... just kind of guess what it would do. Also its below 3 microns so it will even pass through the oil filter - its that small...
let the discussion begin...

I've been wondering this myself for sometime. I am not sure if you could completely rule out oiling since the oil is not only used for antiwear/friction reduction.

Current engine oils that contain organic molybdenum disulfide and/or tungsten disulfide actually do deposit themselves on engine surfaces. So you would have a nano-layer of MoS2/WS2 on the engine. Despite performing better than MoS2, the problem with organotungstates is that they are somewhat annoying to make commercially compared to organomolybdates.

I did want to totally rule out the oil, but it would be a great additive for oils. Full Synthetic plus a couple of oz of WS2 would make it not perform better but last longer. But I know it takes a while to coat the whole motor. I just dont know how much WS2 is for a oil change and if the motor is completely covered with it...

[teknorpi]

Usually a good number is anywhere around 500 to 1000 ppm Tungsten (or Molybdenum) in the form of an sulfurized-organic molecule.

I am not aware of a fully formulated motor oil that contains organic-Tungsten yet. Quite a few patents on organic-tungstates have been popping up lately - however, none of these patents show any friction benefits (organic molybdates are still better). I am sure they are coming though - it all depends on who gets the interlectual property first. ;)

Also, if you find a non-approved motor oil that contains WS2, I wouldn't throw it into your Audi. Some motor oils can wreak havoc on your viton seals.

So I ended up seeing the WS2 in powder form and in .5 microns. This stuff is slick as heck. Acutally so slick that when oil drop was placed on it, the oil actually beaded off it.
So its doing its duty. I am going to place a teaspoon or two or three in another vehicle I have to see if it actually does what it claims to do. I do not have a doubt that it will but the suspension on it is what I am interested in. Will it settle overnight. I have that test going on now and I will write about it later.. but definitley interesting stuff...

where did you find it?

[Unispeed]

powder eh? Any chance this will plug up oil lines?

[S4-Casa]

dyancron has it also there is a company in canada - lowerfriction.com - 45 bucks for a pound. Plug up oil lines dont think so, because it is soo small the oil is usually coked on the oil lines and this stuff is smaller and gets into cracks that oil will not fill. Since the oil actually beads on this then the oil cannot coke as fast. Also the temperature rating on it is -300f to +1000F and oil is ALOT lower. Sythentic is like -70F to +500F. Also the oil filter will not capture it at all since is so small. Now the test. It did not settle at all overnight and I am going to see what happens in a week now.
Tried in a Jeep 5.9L and dont know if its a head shot but the motor does sound more peppy.. more to come..

How much of this do you put per quart? Is there a US distributor?

nobody answered the question I posed in post 9...

Casa,

Yeah, WS2 is pretty slick stuff, it has some of the lowest coefficient of friction of any solid material.

I know people have been selling solid PTFE (Teflon) powders to put in motor oil for decades (mostly snake oil) and more recently as sub-micron PTFE powders. I think WS2 powder has more of chance to work as the molecules should embed themselves into the metal surfaces that see friction or wear.

I don't know if you have done this yet, but keeping the solid suspending might be a problem if the car sits idle for any amount of time. If you are going to add it, I would do it before you go driving for a while. As you drive, the WS2 should impregnate itself on to areas that see high friction.

A gram or two per quart would be good. Around 1000 ppm Tungsten.

[S4-Casa]

The only distributor I know is in Canada and Chicago. Canadians are their importer so I would just go to them.
lowerfriction.com is the site...cheap at 45 for a 1lb..
