There are many aftermarket lubricant additives that claim a multitude of things, improving the performance of industrial grease and oils. If you visit any automotive or hardware store, you will see multiple brands and varieties of these products. Some of the claimed benefits of using these products are reduction of wear on mechanical components, increased horsepower and improved fuel economy of engines. But what makes aftermarket lubricant additives special? Do they really have benefits?
If you look at the product data sheets of the additive products, all are very similar. Most products are made of SAE 50 as the base oil with standard additives, which is very similar to your standard lubricant package. An exception is the PTFE or polytetrafluoroethylene.
PTFE was invented more than five decades ago and the company behind it claims that it is not useful as an ingredient in oil additives or as oil for internal combustion engine. The PTFE has also been tested by renowned institutions, one of which is NASA.
According to NASA, their tests revealed that oil additives containing PTFE offer no benefits. In some cases, the effect was detrimental. The solids in the oil had the tendency to accumulate at inlets or passageways, preventing oil from entering and depriving parts of the lubricant.
Truth be told, there are no credible studies that back the claims of these additive products. There is a reason why there are so many fines and lawsuits levied against aftermarket additives companies. Have you ever wondered why no car or equipment manufacturer recommend the use of these aftermarket additives?
