Avoid wrong way of car maintenance

Wrong way of maintenance 1: hot sun rushing car

Many car owners in the relatively high temperature, afraid of the car because of the high temperature of direct sunlight damage, and use cold water to wash the car, in fact, this behavior can not really do to care for the car, for the car to cool down, but instead of thermal expansion and contraction of the reason will make the car paint surface damage. After exposure to the sun and driving, the surface of the paint and the engine temperature is very high. At this time you want to come to a rinse inside and outside, good guy, the paint surface will be able to make do with your torture, at best, is the future loss of a piece of paint and so on, but the engine will immediately strike, do not let you break the cost of a thousand or so by no means back to work.

Wrong way to maintain 2: add mushroom head

Many car owners feel that the car engine after a certain period of time driving, running is not strong enough as a matter of course, directly in the air intake to add the "mushroom head". "Mushroom head" is called high-flow style, is a high-performance air filter, from the theory that can really increase the air flow in the engine, so that the engine compartment combustion is more adequate, power performance has been improved. But for the northern air containing a lot of fine sand and dust, increasing air intake also brings more fine sand and dust into the cylinder, causing early engine wear and tear, rather than affecting the engine's power performance.

Wrong way of maintenance 3: car mess put fragrance agent

Many car owners because of the bad air quality in the car, there is a bad smell and choose to add air freshener. According to experts, air freshener is synthesized by a variety of chemical components, it does not decompose harmful gases, just by emitting aroma to cover the odor, by confusing the human sense of smell to "lighten" the odor. These substances in the air after the chemical decomposition of the gas itself is an air pollutant, but exacerbated the degree of air pollution in the car. Long-term use of the human body will produce adverse stimulation, poor quality aromatherapy will also be harmful to the human nervous system.

The wrong way to maintain 4: the more oil you add, the better

The role of oil is mostly used for machine lubrication, and many car owners in order to save time and money as much as possible on a one-time oil, but more than a good thing. If the oil is too much, it will increase the internal workload of the engine, the engine in the work of the crankshaft handle and connecting rods will produce violent churning, not only to increase the internal power loss of the engine, but also increase fuel consumption. The resulting increase in oil splashed on the cylinder wall, easy to produce oil burning, resulting in poor engine lubrication. The amount of oil should be controlled in the appropriate range, between the upper and lower scales of the oil scale.
