You can buy a pound for about $50 from a wholesale supplier, and 6 oz. for less than $30 from a shooting supply store.
I'm genuinely curious to hear others' thoughts on this.
I spent several hours yesterday scouring sporting goods stores for powdered moly for just this purpose, but was completely unable to find some. I did find some on eBay pretty inexpensively at roughly $18 shipped for 4oz of ultra fine 98.8% pure powder. I want to use it in some gear oil, so I plan to mix a tablespoon of it into a quart of 75w-140 to see if it will settle out or stay in suspension. If it stays mixed for at least a couple of days, I intend to use some in my rear differential, as well as my power transfer unit. I will also use it for an inexpensive replacement for Lubro Moly MoS2 because of its insane price increase.
Google Rosemill Industries. While its not cheap you can buy ultra fine grade moly which won't get trapped by an oil filter, sold by the pound. I bought it for coating bullets and have also mixed it with MMO or oil for treating engines. I bought it long before the popularity of LM MoS2 on this board, I'm pretty sure its gone up in price, but might still be worth it for you. HTH
I just checked - Rosemill has a pound of 1.5-micron moly powder for $48.50 plus shipping.
I found 6 ounces of Lyman Super Moly "Superfine" (1.5 micron) powder at the Lyman Products web site for $24 plus shipping.
Back of the envelope calculations get me 600 ppm of moly with about 0.5g of MOS2 powder per quart of oil, if the oil has no moly in its add pack. For my applications, that's a shade less than 2g per OCI in the xB and about 2.2g in the wife's Ody.
I don't shoot, and I won't use more than about 2.2g per OCI in my current vehicles. So, 6 oz is enough to last me about 17 years, assuming similar sump sizes in future vehicles. A pound would last me almost 45 years, and I doubt I'll do my own oil changes when I'm 89. I think I'll pay the additional dollar an ounce for a quantity I'm more likely to use.
Lyman on order.
