It is frequently used as a break-in additive for new engines or as a long-term protection solution for equipment subjected to severe operational stresses. For surface treatments, such as protecting stored engines, a thin film can be applied directly to components before assembly.

Applications in Engine Break-In One of the most common uses of moly oil is during the break-in period of a new or rebuilt engine. This makes it a preferred choice for racing engines, classic cars, and industrial machinery that operate outside standard temperature ranges.
Many engine builders recommend a break-in oil containing moly to achieve optimal seating of piston rings and to extend the longevity of the freshly machined components. Its long-lasting properties mean that fewer oil changes may be required, indirectly contributing to reduced waste.

While molybdenum compounds are generally considered low in toxicity, prolonged skin contact or inhalation of concentrated dust should be avoided. It is typically added directly to the crankcase before an oil change, allowing it to mix thoroughly with the new base oil.
