From oil to power: Why are only a few oil products free of additives?
In the world of modern internal combustion engines, the performance of an oil does not only rely on its base oil, but also requires the synergistic effect of various additives. The presence of these additives improves the performance of the lubricant and ensures long-term operation of the engine. Therefore, almost all commercial motor oils on the market contain additives, except for a few American Petroleum Institute (API) service SA models. These oils lack the additives to protect modern engines, which makes one wonder: Why are these additives so important?
Oil additives are chemical compounds that improve the lubricating properties of base oils.
Types of Additives in Oils
Oil additives are vital in lubrication and extending engine oil life. Different types of additives can meet specific operating needs, such as lubrication requirements under extreme conditions such as high temperature and pressure. Here are some key types of additives:
Additives to control chemical degradation
Detergent additives, such as magnesium sulfonate, can effectively remove impurities from the oil and prevent the formation of sludge. In addition, anti-corrosion and antioxidant additives slow down the oxidation of metals, protecting the stability and operating efficiency of engine parts.
Typical antioxidant additives include organic amines and phenolic substances.
Viscosity Adjusting Additives
Viscosity improvers increase the viscosity index of an oil, ensuring it does not become too thin at high temperatures. They also improve low-temperature fluidity, properties that are essential for many motor oils.
Lubricity Additives
Friction modifiers, such as molybdenum disulfide, are effective in reducing friction and improving fuel economy. Extreme pressure agents can keep metal surfaces isolated under high pressure, thus avoiding direct collision and wear.
The development of nanoparticle technology can improve lubricity and achieve superlubricity.
Pollution Control Additives
Dispersants keep contaminants suspended in the oil and prevent them from agglomerating, while anti-foaming agents help reduce the formation of bubbles during operation, thereby reducing the risk of loss of lubrication effectiveness.
Other special functional additives
The sealant swells the seal to reduce oil leakage, which is especially common in high-mileage engine oils.
Aftermarket Additives and Controversy
In addition to the additives in original motor oil, there are many aftermarket additives on the market. However, most popular aftermarket additives often use additives that are incompatible with motor oil. This has caused confusion among consumers, with some users believing that aftermarket additives may not necessarily improve the performance of their engines.
ConclusionThe effectiveness of aftermarket additives has become a hotly debated topic as many consumers disagree.
All in all, pig additives play a vital role in keeping motor oil running efficiently, extending its life and protecting your engine. While a wide variety of oils and additives exist on the market, consumers should choose carefully to ensure their vehicles receive the best protection and performance. What effects do so many additives have on different oils? Is this still a thought-provoking question?
