It does not have mos2, but it has ceramic particles. It coats everything that is exposed to oil. It will reduce valve chain chatter, improve mpg, lower engine temperature and wear on an engine. The car is quieter and no more tinny sound when first starting which lasts about 5 to 10 seconds depending on outside temperature.

It idles much smoother when the engine is hot now. It does not make up for lost bearing material. It is suitable for use on motorbikes with wet clutches.
