As the weather turns cold, ordinary lubricating oils will become thicker at low temperatures and fluidity will be reduced, making the vehicle less easy to start and wear. Therefore, owners of ordinary lubricants must not forget to change their oil.
General lubricants are preferred
Lubricants should be selected based on the requirements of the engine. It is not possible to use excessively high-grade engine oils on less demanding engines, nor to use lower-grade engine oils on more demanding engines. The choice of lubricating oil can be increased by one level on the basis of manufacturer's recommendation, or the performance of synthetic oil can be better.
In addition, there are common oils for winter and summer on the market. Universal oil can maintain a stable lubrication performance regardless of temperature changes, and plays a better protective role for the engine. Therefore, this oil is the best choice.
If the engine is new or in good condition, use less viscous oils such as 0W-40, 5W-40, and 10W-40 as much as possible to make the oil flow faster and reduce wear on startup. If it is in the hot season or the engine has been worn to a certain extent, we must use high-viscosity oil, such as 15W-50, which is conducive to the formation of a thick film, maintain the pressure of the oil, and reduce oil consumption.
No additives in lubricants
Experts said that it is generally not recommended to add additives to lubricants. Because the lubricant itself is composed of a base oil and additives, its formulation has been tested and screened. The addition of additives may be counterproductive, which not only reduces the original cleansing and antiwear properties of the lubricating oil, but also increases the sludge and carbon deposition, which affects the performance and service life of the engine.
Professionals advise that at the same time when replacing lubricants, lubricant filters generally need to be replaced, so that new replacement lubricants can perform better. The lubricant products of different brands cannot be mixed.
There are tricks to identify good and bad
There are many fake products on the market, many owners can not identify the quality of lubricants, and now teach you a few tips. The first thing to observe. If the oil is clear and yellow-brown, the quality is better; if the color is cloudy or emulsified, it means that there is more water; if the oil has a burning odor, it indicates that it is oxidized prematurely or mixed with other oils. The second is to see if there are sediments, sediments are not good oil. Third, the oil can be dropped on the iron plate or exhaust pipe above 110°C. If there is a popping sound, it means that the oil contains water.
In fact, the safest way is to go to a designated dealer, a big brand gas station or a repair shop to buy or change oil.
LED Household Heat Sink FEATURES:
We use Cold chamber die-casting machine to cast the LED Heat Sink. Its integrated structure and thin fin could maximize the thermal dissipation area. Both Aluminum and Zinc are acceptable.
However, the height of Heat Sink in this process and the shape are limited.â— To get very thin/ dense/ high fins to gain max area to dissipate heat in a limited area.
â— Reduced thermal resistance - no more additional material is required
â— Long-lasting durability for frequent use
â— Creating excellent surface for heat dissipation
