Motor oil, Engin oil, or engine lubricant is any of various well-developed lubricants (comprising oil enhanced with additives, for example, in many cases, extreme pressure additives) that are used for lubrication of internal combustion engines. The main function of these lubricants is to reduce wear on moving parts; they also clean, inhibit corrosion, improve sealing, and cool the engine by carrying heat away from moving parts.


Characteristics :

Best quality world wide.

Excellent oxidation stability, low temprature startability.

Great capability of cleaning.

Excellent oxidation stability, low temperature startability.

Great capability of cleaning and dispersing, which lowers sediment generating, as long as the wear of engine.

Great capability of anti-*wear, which prolongs engine working life, lowers consumption of fuel.


Description :

Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stok derived from crude oil, with additives to improve certain properties. The bulk of typical motor oil motor oil consist of hydrocarbons with between *8 and *4 carbon atoms per molecule. one of the most important properties of motor oil in maintaining a lubricating film between moving part is its viscosity. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics. SAE viscosity gradings include the following, from low to high viscosity : 0, 5, *0, *5, *0, *5, *0, *0, *0 or *0. The numbers 0, 5, *0, *5 and *5 are suffixed with the letter W, designating they are "winter" (not "weight") or cold-star viscosity, at lower temprature. The number *0 comes with or without a W, depending on whether it is being used to denote a cold or hot viscosity grade.


Other Applications :

Motor oils are recommended for all four-stroke gasoline engines used in passenger cars, light trucks, power boats, motorcycles, and other mobile and stationary equipment. They are excellent for high revving engines in small cars and light trucks. All grades are specially formulated for using in trubocharged engines.
