There are lots of aftermarket lubricant additives with claims of enhancing the performance of your industrial grease or oil. How true are these claims? And what makes after market lubricant additives special?
The claims of these additives improving lubricant performance are largely unsupported. If you visit an automotive store and look at the data sheets for their additive products, you will find that almost all are identical. Most of the supposedly special aftermarket lubricant additives use SAE 50 base oil and the typical additives found in your standard lubricant packages. An exemption are the lubricant additives that use polytetrafluoroethylene or PTFE.
However, PTFE has been found out over and over to have no beneficial effects. PTFE was designed more than five decades ago. The company behind the compound stated it offers no advantage as an active ingredient in lubricant additives and oil packages for internal combustion engines.
PTFE lubricant additives have also been tested by NASA. Their tests revealed that the products offer no improvement in the performance of the lubricant. In some cases, the use of the additives had negative effects. The solids in the additives had the tendency to gather at inlets or paths, preventing the passage of oil and depriving parts of lubricant.
Simply put, there are no trustworthy studies that support the claims of these aftermarket additives. There is a reason why there are a lot of fines and legal actions being taken against companies that produce these additives. There is also a reason why machine and car manufacturers don’t recommended these sort of products.
