The Use Of Lubricating Oil Should Not Blindly Pursue High Viscosity

The viscosity level of lubricating oil is very important for the normal operation of the engine. In order to prevent the wear of the contact surface between the moving parts of the engine, the lubricating oil should have sufficient viscosity so that the oil film can be formed between the moving parts at various operating temperatures, so as to make the smooth operation of the automobile engine. But there are some drawbacks to using excessively viscous lubricants.

Today for you to introduce in detail the use of annual excessive lubricating oil what harm?

One: may cause wear and tear

When the engine is too high to start Chengdu, it is likely to cause serious wear when the engine starts. Because the viscosity of lubricating oil is too large, the flow is slow, and the oil pressure is reported, but the amount of lubricating oil through is not much, and it can not be timely added to the friction surface. Some cycles also slow down, and cooling and heat dissipation become poor, leading to overheating of the engine. Because the lubricating oil circulation speed is slow, the number of times through the lubricating oil filter is less, so it is difficult to timely wear down the metal chips, carbon particles, dust from the friction surface cleaning out.

Two: Energy consumption

Because the viscosity is too large, the friction between the friction surfaces of the machine increases. In order to overcome the increased friction, more fuel will be consumed, resulting in a huge waste of energy. Although there is no mandatory requirement for energy saving of domestic lubricating oil, low viscosity will be the development trend of lubricating oil in the future.

Therefore, in the alternating seasons, the driver must pay attention to the viscosity of lubricating oil, and will often check the quantity of lubricating oil, oil quality, and timely replacement, at the same time, different brands of lubricating oil ** do not mix. It is recommended that the owner use the best lubricating oil additives, regular use, can ensure that the engine as far as possible to avoid overhaul, prolong its life.
