Engine Oil

Engine Oil
Engine lubricant, also known as engine oil, is composed of base oil and additives, with base oil serving as its main component, Lubricant is featured by its multiple engine-benefiting effects, such as lubrication, abrasion reduction, auxiliary cooling, sealing, rust resistance, corrosion prevention, shock absorption and buffering.

Functions:
1.Lubrication: Engine lubricant forms an oil film between piston and cylinder, and thereby separates the fiction surfaces of both components to reduce friction, which is its most significant function.
2.Detergency: Engine lubricant can bring carbon deposits, oily filth and abraded metal particles from engine components to the oil pan by circulating in the lubrication system.
3.Sealing: Engine lubricant forms an oil film on the friction surfaces of engine components and plays a role in sealing, thereby reducing gas emission and oil leakage, and keeping external pollutants away from entering the engine
4.Rust resistance and corrosion prevention: The oil film can adhere to component surfaces, thus prevent water, air, acids and harmful gases from contacting those components and avoid oxidative corrosion.
5.Cooling: Engine operation will generate high temperature. Engine lubricant reaches the operating part, absorb the heat and then take it away. Some of the heat from the operating engine is brought back to the lubricant tank and then dissipated away through circulation in the engine lubricant system.
6.Shock absorption and buffering: An starting engine will drive up the cylinder port pressure sharply, and thus increase the load upon piston, piston pin, connecting rod and crankshaft bearing suddenly. As such load is transferred via lubricant, the shock is absorbed and the vibration is reduced by the lubricant that works as buffer.

Classification:

Automobile engine lubricants are mainly divided into two kinds, namely mineral lubricants and synthetic engine lubricants; the synthetic engine lubricants can be further divided into fully synthetic engine lubricants and semi-synthetic engine lubricants.

From the perspective of composition, fully synthetic engine lubricant contains no mineral lubricants while semi-synthetic engine lubricant contains a small amount of mineral lubricants. Mineral lubricants are reined from petroleum and then mixed with additives, boasting their low costs. Synthetic engine lubricants are synthesized through chemical methods. Despite their high costs, they present a better high-and-low temperature performance and a longer service life than mineral lubricants.

Engine Lubricant SN Series

Lubricants of SN grade are divided into fully synthetic and semi-synthetic types: The fully synthetic lubricant is featured by its high antioxidant stability, high abrasion resistance, low phosphorus and zinc contents, and reduced three-way catalytic converter loss. SN engine lubricant is mainly improved regarding its high temperature detergency, SN requires an oil ring blockage rate no more than 15% and therefore particularly applies to turbocharged engine. The semi-synthetic lubricant of SN grade is featured by its excellent low-temperature fluidity and effectively reduced cold-starting abrasion; its low evaporation formula technology can effectively reduce engine lubricant consumption, thus presenting a better cost-efficient performance than that of fully synthetic lubricant.
