Tungsten Disulfide (WS2) lube additive

Postby Trevorski » Fri Nov 25, 2016 2:01 am

Around late July 2016, I was doing a complete change of engine/ transmission/ FD fluids, and (at about 4200km on the bike) decided to put in some Tungsten Disulfide (WS2), a nanoparticle of a material that (like the more common Molybdenum Disulfide found in many greases and other lubes) "plates into" metal moving parts to reduce friction. Like "Moly' the principle is that the particles of WS2 adhere into the pores in the steel and create a smoother surface with less friction.

I'd deliberately _not_ done the WS2 at lower km because I did not want to stunt the natural 'bedding in' of parts during earlier break-in.

Source for the WS2 was
http://www.lowerfriction.com/product-pa ... tegoryID=1
and at 0.6 microns, it should flow through rather than clog oil filters.

I added some WS2 for the new fluids for the engine, transmission, and FD; at the moment as I am writing this, I forget the ratio of WS2 but I followed recommendations. It needs to be mixed into the old (I did this by shaking), and since it is a very heavy, dense compound that will be prone to settling out, I put in the WS2/new lube at a time when I could take the bike for an immediate ride, and chose a route that allowed for a lot of running at different loads/gears/speeds to try to keep the WS2 particles circulating and distributed over as many surfaces as possible.

Observations- adverse- none to date

Observations- favorable: my transmission, which had already been smoothing gradually up over the accumulating kms, smoothed WAY up during that first ride with the WS2 and has remained smooth and shifts better than at any point prior to the WS2. Engine smoothness and responsiveness have continued to increase, but I am unable to separate how much of that is the WS2 and how much of it is just that the rig's moving parts are getting more and more broken in...

Interesting read Trevorski! Thanks.
I wonder how it'd compare to motor oil with ZDDP additive, which some motorheads recommend on flat tappet engines.
Please keep us posted on your real world testing of this additive. Laboratory testing is nice but real world application, to me, is more relevant. Lots of variables in real world testing events vs controlled testing in a laboratory environment. I've been exposed to both, lab tests are educational but actual application is when the "rubber meets the road". :mrgreen:

I was thinking exactly the same thing.

I often wonder how much of any improvment after a change like this is real and how much is imagined. When I was younger, I swore that my bikes and cars ran better after I'd w@$#ed and w@*ed them. :wink:

I run a 10% mix of molyslip (Molybdenum disulphide based) and SAE 90 in my diffs and FDs. Not in gearbox or engines of my Dneprs.

The problem I see with an additive like this in anything other than a gearbox or FD is that it settles out. So, when you park the bike, think of all the places it can settle out. My concern would be things like oil galleries and in our case slingers would get packed rather rapidly. A crank could possibly even be taken out of balance by it settling in the slingers when stopped.

The only way I would put this in the engine would be to add the oil mixture containing WS2 then go for a long long ride so the WS2 could get into the pores and then change the oil and filter as soon as I got home. In theory the excess WS2 would be removed.
