The base of motor oils, referred to as mineral oils or minerals, is crude oil, which turns into complex products for final consumption in cars. Of course, in recent years, apart from the type of mineral, the engine oil is also divided into two types of semi-synthetic and all-synthesized, which in fact are kinds of engineered oil. The duties that lubricant oils drive in the car are briefly:
A: Lubrication: Minimizes friction and wear between parts during operation
B - Heat transfer: Remove the heat generated in the engine and cool off the moving parts
C-Sealing: By forming a layer of oil between the piston and the cylinder in the internal combustion engine in order to prevent the escape of dense gases.
D-Blow-up: absorbing some of the vibrations and blows during mechanical operations on the parts
E) Material Transfer: The transfer of particles caused by the wear of parts as well as the combustion of oil and fuel decomposition
Most of the tasks above are the additives that are added to the base oil. At the same time, these materials darken the color of the oil, but do not expose it. In order to always have a cool car, we should do the following to hair.
1. Oil alone is not a suitable criterion for determining the quality of engine oil, and only experts can comment on the quality of the oil to some extent by examining the appearance and, finally, carrying out the relevant tests. The additives used in engine oil usually darken its color. The quality of lubricated motor oils is darkened by the absorption of metals from the wear and tear of parts on each other, soot from combustion, dust and other pollutants. But the difference is that the oil is unbleached in their transparency, so that the oil has a special, clear, slightly dark additives. But the oil worked in addition to being dark, is also cloudy, and the blackness of the oil paint oil during operation does not indicate a loss in oil quality, but indicates the proper functioning of the engine oil and gradual consumption of engine oil additives, and therefore blackening The color of the engine oil does not indicate the time of its replacement, and the recommended mileage of the automaker and the company producing the motor oil will be effective. So, if the oil does not change after a while, it is a sign of the inability to convey waste and sediment from the portions of the parts and, consequently, inappropriately.
2. The type of engine oil used must be appropriate to the type of motor vehicle. In this case it is necessary to refer to the vehicle's manual and consider the manufacturer's recommendation.
3. The engine oil should have adequate knowledge of the quality level standard and the actual engine oil scanner.
4. It is more reliable to use the oils of the manufacturer's manufacturer, which is included on their packaging, the relevant specifications, including the quality level and the appropriate kilometers of operation.
5. Adjustment of the engine is necessary in order to prevent additional pressure on the parts and also to check the condition of the engine oil.
6. Operating conditions of the engine, such as operating time, load, temperature, humidity and other environmental factors, have a direct impact on the performance and quality of the engine oil.
7. Replacing timely air and oil filters, as well as washing the body of the engine, increases the life of the oil.
8. The quality of the tires and its wind setting will reduce the load on the engine and delay the time of engine oil change.
9. The stagnation of oil inside the engine is not a reason to maintain its quality, but after four to six months for low-quality oils and six to 12 months for high-quality lubricants, oil has to be replaced. . To determine the exact time, you should consider the manufacturer's recommendations.
10. The oil level indicated on the measuring rod, located in the oil tank, must always be between the two letters L and H. In general, if it is closer to the lower line or L, it is better to reach H or the upper line.
11. If the amount of oil is reduced, the added amount should be of the same type.
12. Proper viscosity or viscosity is an important characteristic of the engine oil. Further depreciation, engine heat buildup, higher fuel consumption, and late cold-air cooling are among the disadvantages of not choosing the right viscous oil with viscosity.
13. In order to ensure proper functioning, it is better to use multi-degree or multi-grade oils, which are also said to be quaternary.
14. Conditions such as high or long-term driving, high temperatures, steep slopes, very short distances, alternating engine exits and turns, traffic in heavy urban traffic and high sulfur content (in diesel engines). Increases engine oil, reduces its quality and longevity.
