I hope not, I have some coming in the mail..
Supposedly not..
Moly click here
Engineers and scientists have tried for years to use Moly in motor oils but they had been unsuccessful because they could not find a way to keep Moly in suspension. Once Moly was put into suspension it would gradually settle out. It was easy to see it come out of suspension because a black sludge would collect on the bottom of the oil containers. In engines it would settle to the bottom of the crankcase or clog oil pathways and filters.
Engineers have overcome these obstacles. They have developed a process that keeps Moly in suspension and isn’t filtered out. Since that time theproduct has undergone extensive independent testing in labs and in the field for many years to insure that the product stands up to the rigorous needs of today’s engines. With the plating action of Moly reducing friction which reduces heat, this helps keep rings free from carbon buildup, prevents blow-by, decreases emission, and extends oil life.
The moly doesn't get filtered out, however MOS2 will fall out of suspension in engines that aren't used everyday. Case in point, Trav had posted MOS2 settled in the bottom of an oil pan in one of his vehicles that wasn't driven on a daily basis, [it sat for weeks sometimes months at a time]. Several other respected members had posted similar observations over the years which is why I stopped using the product. There are better moly choices than MOS2 for moly as part of an ad pack that oil makers use for that very reason.
I recall a discussion I had with Trav about Ceratec falling out of suspension in a compressor he tried it in as well.
