Engine Oil
The lubricating oils used in various kinds of internal combustion engines (automobiles, boat, airplanes, grass cutter, mist blower, water pump, etc) are generally referred to as engine oils (or motor oils). One of the most important properties of engine oil is its viscosity, where it must be high enough to form an effective lubricating film, but low enough to be able to coat the engine parts properly under all conditions. Engine oils with different viscosity ranges are generally divided into single- or multi-grade, categorised by SAE numbers. Engine oils are further categorised by other standards (API, ILSAC, etc) based on their performances, in terms of anti-oxidation, anti-wear, detergence, foaming and other properties.


Greases are commonly used where the lubricant is required to stick to the contacting surfaces, or where high pressure is present. Many types of greases are available. They range from the calcium-based for general use, to the lithium-based for applications that require better moisture resistance and higher temperature, and the molybdenum-based for extreme conditions.


Slideway Oil
The use of water soluble coolant in modern automated machine tools, especially the CNC machines, is growing rapidly. These coolants are normally delivered at high pressure and flow rate. It is hence important for the slideway oil used to provide a film with excellent lubrication characteristics to minimise the ¡°stick-slip¡± problem, and yet exhibit good adhesion property to minimise the ¡°wash-off¡± effect. It is also desired for slideway oil to have rapid demulsification ability which allows tramp oil to be easily skimmed off for extended coolant life. Other important properties of slideway oil are excellent anti-corrosion and anti-wear.


Gear Oil
Gear oil is specially designed for use in transmissions, differentials and transfer cases. Its viscosity is typically higher because most of these devices do not have pumps for transferring the oil. The higher viscosity ensures that the lubricant from the lower portion of the gears bathed in the oil sump to be carried and transfer throughout the gear train when the gears rotate. EP and anti-wear additives are common ingredients to provide good protection for the gears.


Hydraulic Oil
Hydraulic systems are designed based on the principle of Pascal¡¯s law, where energy can be transferred from one point to another through the hydraulic fluid. Selecting a fluid with the right viscosity is therefore important in a hydraulic system, which depends on fluid flow for energy transmission. Hydraulic oil is also required to lubricate and protect the internal component of the hydraulic system, requiring the oil be formulated with good anti-wear and anti-corrosion properties.


Compressor Oil
Compressors are machinery that elevates the pressure of a compressible medium, normally air, and other types of gases. The most common compressors are the reciprocating and rotary types. In most of the applications, petroleum-based lubricants which exhibit high level of oxidation stability, wear protection and demulsification ability are excellent choices.


Auto Transmission Oil
The designs of automatic transmission systems are under continuous improvement for increased durability and efficiency. These changes would require the transmission oil to operate under tougher conditions such as elevated temperature. It is imperative that the auto transmission oil is required to possess superior thermal, chemical and oxidation stability. The two most common categories of auto transmission oils used today are classified under Dexron and Mercon.


Cutting Oil
Cutting oil, or commonly known as coolant, is used to lubricate and cool the cutting tools and the pieces they are operating on. In order to achieve the increased requirements of high production yield, and to address the safety and environment issues, the use of water soluble cutting oils is gaining popularity.
