Engine oil consists of 2 main components: base oil and additives. Base oil has many properties of the finished oil but is incomplete, so additive addition is necessary for the best performance. Join SK ZIC for more details and additives used in lubricants!

The role of the additive: an additive makes up only about 20% of the finished oil, but has many important benefits such as:

• Enhances the essential features that the base oil currently has.
• Remove unwanted base oil properties.
• Adds new features to base oils.
• Depending on the purpose and application, the additive is selected and added in reasonable amounts.

Several types of additives are common in lubricants:

• Friction regulator (FM):

When two surfaces of the workpiece are in contact with each other, there will appear a drag, which is friction. Friction causes abrasion, abrasion and reduces equipment's performance. To reduce this friction, use appropriate lubricants. Friction regulator enhances the lubricant's friction reduction and surface protection properties.

• Viscosity index enhancer:

Viscosity is an important property of a lubricant that largely determines the efficiency of the lubrication process. Viscosity is affected by temperature, the temperature increases, the viscosity decreases, and vice versa. Viscosity index (VI) is a quantity that characterizes the oil's ability to change viscosity with temperature. The higher the index the less the viscosity change and the better. Adding the additive VM helps to stabilize the oil and increase the viscosity index.

• Antioxidant Additive (AO):

Working oil exposed to oxygen for a long time will discolor, decrease quality and create a humus residue. When the oil works at a high temperature, the quality reduction process will accelerate many times. Anti-oxidant additives help prevent the effects of oxygen on the oil, prolonging its performance.

• Cleaning additives

Lubricant after a period of use will contain a lot of dirt. This residue is caused by the equipment in operation, by dirt from the air, and by variations in the oil. Cleaning additive works to pull dirt off the metal surface, convert harmful by-products to oil into harmless substances, prolong oil life.

*Conclude:

• After a period of use, the additives in the oil will gradually deteriorate and lose their function. Therefore, the oil needs to be changed on time to protect equipment.
• Lubricants made from high quality Group III, IV base oils that are more durable and provide many features without the need for many additives
