What the meanig of «Additives»?
Additives are chemical compounds that are added to oils and greases in small amounts to improve their performance. Additives can change the physical and chemical properties of a base oil to improve its performance in certain conditions or environments.
The most common types of additives are:
– Anti-wear additives form a protective film on surfaces, reducing friction and wear between parts.
– Detergent additives help keep engine components clean by preventing the formation of sludge and deposits.
– Dispersants help prevent formation of harmful deposits and sludge by suspending contaminants in the oil itself, allowing them to be removed from the engine lube system with the oil during oil changes.
– Antioxidant additives help prevent oil from oxidizing and thickening over time.
– Viscosity modifiers help maintain oil viscosity over a wide temperature range, improving its ability to lubricate and protect engine components.
– Friction modifiers reduce friction between moving parts, improving fuel efficiency and reducing engine wear.
– Low pour point additives help prevent oil thickening and loss of fluidity at low temperatures, improving cold weather performance.
By adding these and other types of additives to oils and lubricants, lubricant manufacturers can tailor their products to the specific needs of different engines and operating conditions. The right combination of additives can help improve engine performance, extend engine life and reduce maintenance costs.
