Read up on the WS2 and let me know your comment

Oh WS2, I read about these IF tungsten disulphide a couple years ago but back then, no product was ever used using this powder or solid lubricant. So casual users like us have very little or no data on it. Heard it used to be very expensive thus although its an excellent lubricant but cost is not practical then.
Not sure abt the current tech tho.
WS2 is a solid-based or originally powder-based addictive mixed with other oils (probably mineral or high grade minerals) with very high lubrication capabilities with its IF nano particles that can adhere to surface and fill in gaps (excellent), it might bond very well onto the engine parts which is a good thing to protect the parts.
However as with all other solid addictive, my main worry is when over long term, these bonded film might also accumulate sediments from the engine oils over a long period of time especially when constantly used near 10K mileage in our humid and dusty driving environments.
I'm not sure if it might eventually clogs the valve and pipeline of the engines over long period of its usage. Unless the brands also produced engine oil THAT you used along with this addictive (which guaranteed compatibility of addictive used), nobody can be sure that these addictive might cause any adverse chemical reaction with other brands addictive. Maybe the nano thingy helps hold sediments in suspension and not sticking to it.
Will this add. addictive chemical reaction cancelling each other out or make its worse or better, nobody can fully testified to its long term effect due to the variety of different engine oils quality used out there.
GOOD quality engine oils are usually formulated to provide very balanced addictive performance between its anti-wear and lubrication properties. Adding of external addictive might unbalanced these formulas and produce adverse effect.
I have to say, its all only in theory as no one can 100% guarantee it will work or not work with certain engine formulas, thus my adverse reaction to extra addictive not of the same brand as engine oil used. Unsure here does not mean addictive is no good, as a matter of fact, many has testified certain addictive working very well above stock oil properties and I can't rebuke that coz it might as well be true.
However due to my old-school thinking, with so many elements of "uncertain" long term performance and durability (no solid data backup yet) I usually avoid such addictive (although they might be highly effective especially with improved tech nowadays) and keep to proven GOOD engine oil / optimal change period schedule that has PROVEN to usually maintain a vehicle in tip top performance over a long period of time.
It is only my 2 cents and I might have been ENTIRELY WRONG ABOUT IT. A lot of other sifu probably can input in detail MUCH better than me coz I usually only know the overview and can likely KICK my ass again for bullshitting.
My view does not apply to racing kaki tho, these guys know what addictive to use to fine-tune boost their engine (albeit shorter life or not), so to give those extra oomph and performance by seconds.
Final conclusion of WS2 : I know nuts about it.....hahahahaha

Cabut again....

ps..since I type so long since I very free now, bound to have a lot of mistake but I make sure no gear ratio was mention...ya...but other mistake I' don't know....if found, that is old Cavino with jiken comes alive typing, screw him...
