Use of lubricants: 1ã€Changing or using oil is an economical choice Using good oil and changing diligence is a good choice, but many times it does not meet the economical choice of the owner. As a result, choosing between a good oil use of a long time or choosing an ordinary oil for quicker replacement has become a problem that has plagued many car owners. Experts suggest that if economic considerations are concerned, semi-synthetic oils can be selected for ordinary mid-range cars and economical cars, and they should be replaced at about 8,000 km, or full-synthetic oil can be considered and replaced at 15,000 km. Are more economical choices, such as semi-synthetic oil, you can choose Vina's 10-W40, Shell's extraordinary Heineken (blue shell), in the case of all synthetic oil, you can choose Singapore Petroleum's Xinwei 5-W40 It is worth noting that, although it is very cheap, mineral oil should not be among the choices. 2, 4S shop oil combined, proficient in oil owners can choose 4S oil is more expensive. Is it suitable to change the oil in the 4S shop? This should be a problem that is more difficult to answer for 4S stores and car owners because it also involves a warranty issue. The first thing to confirm is that the engine oil provided by the 4S shop must be a qualified engine oil. For those owners who are not familiar with the engine oil, especially the owners of vehicles under the warranty period, if they are not particularly proficient in oil products, the experts suggest that they choose to go to the 4S shop to replace them. Engine oil. Of course, owners who are proficient in automobiles and oil products can make more appropriate choices based on actual conditions. 3, the turbine must use fully synthetic high-viscosity oil Turbine lubricants not only take on engine lubrication and heat dissipation, but also play a role in the lubrication and heat dissipation of the turbine. Due to the effect of the turbocharger, the quality and volume of air entering the combustion chamber are greatly improved, and the engine structure is improved. Compact, higher machining accuracy, more stringent assembly technology requirements. All of these factors determine the high temperature, high speed, high power, high torque, and low emissions of the turbocharged engine. At the same time it also determines the internal parts of the engine to withstand higher temperatures and greater impact, compression, and shear forces. Therefore, in the use of oil, it needs special attention, in the choice of lubricating oil, there are two points that need special attention, the point is to choose high-quality lubricants, we recommend at least the choice of full synthetic oil, the best choice for all synthetic oil, In order to provide adequate protection, the other is to choose a more viscous motor oil, 0-W30 is absolutely the killer of the turbo car, in the high temperature, almost can not provide any effective protection, we recommend the choice of 5-W50 or 10W-50 product. In the turbo car, you can choose Singapore Petroleum's Seiwei 5-W50 full-fat synthetic oil, MOTUL 300V 10-W50 full-lipid synthetic oil, Xinhui full power F1-A 10-W60, to remind that these High-viscosity lubricating oils are not suitable for ordinary street cars. If ordinary street cars with conditions also want to use these high-quality racing oils, they must choose products with lower viscosity levels. Inflatable Toys High Frequency Welding Machine Inflatable Toys High Frequency Welding Machine is a high frequency device, whose self-exited oscillator of the electron tube can produce high frequency electromagnetic field. And the plastic to be processed is in the high frequency electromagnetic field between the upper and low electrode. When its interior molecules are polarized and produce heat automatically by mutual movement and friction, it will be welded with the pressure of the die.
