Oil additive

Oil additives are chemical compounds that improve lubricating performance of base oil (or "base stock" oil). Many different oil manufacturers can use the same basic stock for each formulation and can choose different additives for each specific application. The additives comprise up to 5% by weight of some oils.

Almost all commercial motor oils contain additives, either synthetic or petroleum-based oils. Basically, only the American Petroleum Institute (API) Service SA motor oil has no additives, and therefore they are not able to protect modern machines. The choice of additive is determined by the application, e.g. oil for diesel engines with direct injection in pickup trucks (API Service CJ-4) has different additives from oils used on small gasoline-powered outboard motors (2-cycle engine oil).

Although motor oil is produced with many additives, aftermarket oil additives also exist. The striking inconsistency of the mass marketed lubricant additives is that they often use additives that are foreign to motor oil. On the other hand, commercial additives are also sold which are designed for extended dewatering intervals (to replace spent additives in waste oil) or to formulate in situ oils (to make special motor oil from the base stock). Commercial additives are identical to additives found in off-the-shelf motor oil, while mass-marketed additives have several of each.

Some of the mass-market oil additives, especially those containing PTFE/Teflon (eg Slick 50) and chlorinated paraffins (eg Dura Lube), have caused considerable reaction by consumers and the US Federal Trade Commission investigating many mass-market machine oil additives. in the late 1990s.

While there is no reason to say that all of the oil additives used in packaged machine oil are good and all the aftermarket oil additives are bad, there is a tendency in the aftermarket industry to make unfounded claims regarding the efficacy of their oil additives. These unfounded claims have led consumers lured to add a bottle of chemicals to their engines that do not reduce emissions, increase wear resistance, lower temperatures, increase efficiency, or extend engine life more than oil (much cheaper). Many consumers believe that aftermarket oil additives work, but many consumers believe they are not working and in fact harm the machine. This topic is hotly debated on the Internet.

Although PTFE, which is solid, is used in some aftermarket oil additives, users suspect that PTFE clumps together, clogging filters. Certain people in the 1990s have reported that this is corroborated by NASA and US universities. One thing to note, in the defense of PTFE, is that if the particles were smaller than what appeared to be used in the 1980s and 1990s, then PTFE could be an effective lubricant in suspension. The particle size and many other interrelated components of the lubricant make it difficult to make statements about whether PTFE is useful or harmful. Although PTFE has been called " the most slick substance known to man ", it is almost useless to remain in the oil filter.
