Automotive
At the time machine working, friction occurs repeatedly antar komponen machine. This can lead to wear and tear on the surface. Lubricating oil would create a slippery surface, so that direct friction antar komponen machine can be prevented. The amount of friction can cause the engine to run into over-heat until jam or cause damage to the cylinder and piston, such as irregularities oil pump, oil leakage on the channel, and could also be because of incorrect use of type of oil itself. For that, it's good to follow tips as noted, the following, to use a lubricating oil.
* Type of Oil (Lubricants)
Based on raw materials there are three types of oil circulating in the market, namely mineral, semi synthetic, and synthetic. Mineral lubricant, the material is essentially oil, which is processed into lubricating oils. If then the processed results coupled with other synthetic materials to achieve a better quality standards, then the product is called a semi-synthetic lubricants. Higher quality synthetic lubricant called.
* Standard Viscosity Oil
Oil can be classified from viscosity or viscosity levels. In containers of oil, commonly found code letters and numbers that show it. For example SAE 40, SAE 50, SAE 90, and so on. SAE stands for Society of Automotive Engineers or the Association of Automotive Engineers, which sets the standard viscosity at a temperature of 100 oC. Behind the numbers indicate the level of consistency.
Code numbers such as multi-grade 10W-50 is a viscosity which can change according to temperature in the vicinity. W letter behind the number 10 stands for Winter (winter). So lube it means to have an equivalent level of viscosity SAE 10 (in the cold), but when the hot air viscosity equal to SAE 50.
* Classification of Oil Quality
Classification is determined by the quality of lubricating oil of API (American Petroleum Institute). Classification of the quality of an oil marked with code letters on the packaging, there are usually two parts separated by a slash, eg API Service SG / CD, SH + / CE +, and so on. Code with the letter S is an abbreviation of service (or spark which means spark), is a specification for gasoline engine oil usage. The letter C is an abbreviation of commerce (or compression because the combustion occurs at a higher air pressure), is the specification of the use of oil for diesel engines. Then for the second letter in the code is the level of quality in accordance with the sequence of alphabet letters. The closer the letter Z, the higher or better quality.
* Choose The Right and Qualified
Follow the vehicle owner's manual instructions that we use. If advised to use SAE 20W-50, then do not buy oil with different viscosity standards. Moreover, because the reason is cheaper and so on. For performance and character of its own engine oil specifications require.
* Beware of Oil Asphalt. Purchase or sale of oil in place of the formal workshop.
