“Prevents mechanical loss of engine power and reduces mechanical noise. Even with racing engines built with highly precise components, moving parts such as valves and pistons cannot escape from friction loss. Molybdenum, which is a major ingredient of MT105, quickly penetrates into the metal friction surface. This makes a smooth metal surface by forming a strong lubricating layer, which in turn reduces friction resistance and minimizes loss of engine power. By holding the increase of metal surface friction temperature it stabilizes oil temperature, reduces metal friction noise, and improves engine durability.”
I ran this product by the experts at my favourite oil site a while back. Firstly oils with moly in it tend to be very good, moly is a great anti wear additive. However the type of moly which is good is molydithcarbonate (excuse my spelling if I spelled it wrong ?), commonly found in oils such as Redline, Mobil1, Castrol, and some Penzoils. This moly plates up on metal surfaces with use and remains on the metal surface helping prevent metal to metal contact. You can see engines uptake this moly during oil use. A product such as Mobil1 may contain 60 ppm of moly, at the end of an oil interval you may find 30-40 ppm as the engine has absorbed a portion of the moly which plates up on the metal parts.
This Mugen treatment is Molydisulfide, which is not very good in engine oil, I forget the reasons but its the wrong type of moly, very similar to the Molyslip product which is also no good. This product does not plate up on metal products and reacts poorly with oil by-products.
I was very disappointed to hear that as I expected more from Mugen than that.
Schaeffers Oil makes a great moly additive which works very well, which is used in small quantities with each oil change to boost the antiwear qualities of oils. It is the right type of moly. If anyone is interested I can find a link.

Joey, thanks for that bit of information. I remember running across something about “Moly” additives on http://theoildrop.server101.com I was going to ask you what would be a good brand additive. Now I know.
anti-friction coatings use molybdenum disulfide - I think www.bobistheoilguy.com has a page explaining how it isn't very soluble in oil - as far as the performance goes, I'm not sure the additives will help much if you're running good oil, but who knows? - that blurb about Mobil 1 was interesting, it'd be nice to see the concentrations in other oils
Mobil1 uses about 60-80 ppm of moly, Redline uses over 600 ppm of moly, Castrol GTX uses about 40 ppm of moly, Schaeffers oils use about 120 ppm of moly, some Penzoil oils use about 40-60 ppm of moly. Honda break in (factory fill ) oil has around 400 ppm of moly. Some of these new 5w-20 and 0w-20 oils are using higher concentrations of moly, Castrol's 5w-20 uses 200 ppms, Honda's 5w-20 uses 200 ppms as well. Seems like they need a bit more margin of safety given the thin viscosity , to reduce wear when the oil shears and you get metal to metal contact.
Strangely enough Amsoil does not use moly but it tests very well on its own, often wondered how Amsoil would do with a bit of moly , should be an outstanding combination IMO.

good stuff! read the link on the Schaeffers moly additive, if it really does help decrease oil consumption, I'm probably going to use it with some Amsoil 0w30 - which works great, but there does seem to be significant burn off (minor complaint)
good info and just to think i was going to buy the mugen stuff..
