Many consumers regard the price factor as the primary consideration when purchasing lubricants. They only want the price to be cheap, but ignore the identification of the authenticity of the product. This is easy to give counterfeit and inferior oil a chance.

    The correct approach: The lubricating oils currently on the market vary from good to bad, and it is a more intuitive way to identify the authenticity of lubricating oil by price. Due to the differences in purchase channels, rental costs, etc., when the difference is lower than about 20%, you should be wary of whether it is fake. In addition, check whether the product packaging is clean and beautiful, without oil stains, whether the seal is a disposable lid, whether there is a manufacturer's anti-counterfeiting mark on the sealing foil, whether the oil is transparent, without impurities, no suspended matter, and no sediment, and whether the fluidity is good when shaking. Whether the temperature is mild, etc. are also some simple ways to identify the authenticity.

Misunderstanding 2: "Preferring" foreign oil

    Some car users regard the brand as the primary criterion for choosing lubricants. Some of them said that they only recognize the brands of "Shell", "Mobil" and "Total", but do not trust the quality of other lubricant manufacturers.

    Correct approach: It is not advisable to regard the brand as the oil selection standard. The oil selection mainly depends on the oil grade. At present, it is generally classified according to the quality standards of the American Petroleum Institute in the world. According to the working ability of the lubricant, the oil products are divided into SA to SN grade letters, which means that the quality is one level higher. At present, domestic well-known brand lubricants such as Great Wall, Kunlun, Uni-President, Hafle, Compton, Longpan, Zhonghua, and Zero Kilometer have passed the SN standard API certification. Therefore, for the same grade of lubricants, the brand performance is similar, so the choice of lubricants is diversified.

Misunderstanding 3: The thicker the better

    Some consumers say that in order to achieve better lubrication effect, they usually choose oils with a higher viscosity than the applicable grades when choosing lubricating oils.

Correct approach: Too low oil viscosity can easily cause poor lubrication. In order to avoid this situation, some riders believe that the more viscous the oil, the better. This is actually an outdated view. In the past, lubricating oil was lubricated by an oil film. The thickness of the oil film determines the strength of lubrication. Because the higher the viscosity, the thicker the oil film, so the thicker the lubricating oil, the better the lubrication effect.

Today's lubricants mainly rely on additives for lubrication, instead of relying on thick oil films. Therefore, the view of "the thicker the better" is no longer applicable. Moreover, the lower the oil viscosity, the lower the resistance, the easier it is to start, and the lower the energy consumption. Therefore, under the premise of meeting the lubrication requirements, low-viscosity lubricating oil is now more and more admired for the purpose of energy saving. In addition, the low-temperature start-up type and pumpability of high-viscosity lubricating oil are poor, and the oiling speed after start-up is slow. The correct way is to choose lubricating oil with appropriate viscosity.
