I have decades of experience with moly additive and love the stuff. Most who only try it for a while won'tn notice, it takes years to really see the difference, unless it's a small displacement engine, then it's apparent after a few hundred miles.
First noticed it in all of the military & government specs for my designs. Then started seeing it in extreme application stuff. The mechanical engineers & phyisicists through the years have all confirmed the properties after they searched and read up. For dry lub applications (zero gravity and neg gravity) we used oil/grease with moly and tungston carbide coated (Diversified Dry Lub out of Tulsa OK).
The place I used to purchase from went out of business and am looking for a new source. Bought 5 gallons of the stuff before they were bought out. Don't know the name of the new firm. They advertised partical size 3-5 microns, well below most filter particulate size spec.
Basicly only need to apply one time, but where it's really needed, it does burn/wear off (cylinderwall towards TDC).
On small displacement engines the percentage loss due to friction is much higher ratio to output. In a large displacement it is lost in the noise. After 3K miles and fresh oil/fiter/moly additive and a few hundred miles later will see that the coolent temp will be noticably lower (usually 10-15deg). Only change is moly additive.
Know this sound like a snake oil pitch, but I serious. Take a look at the "speical" break in grease for high pressure spots on high output engine rebuilds. It's all moly based grease. Look at any good extreme application grease, it'll most likely have moly as a component. If you are a shooter, the latest thing is moly coated bullets (been using moly in my adult air guns for years).
