Oil is an indispensable lubricant for vehicles, especially for trucks. If improper use of oil, not only easy to lead to high fuel consumption, burning oil, but also may directly cause engine failure. Here we take inventory, change the oil several common errors, to the majority of card friends to wake up!

Wrong engine oil turns black

A lot of experience is not enough rich card friends, see the oil turned black, it is necessary to change the new oil, but in fact, this judgment is not accurate. Because the oil itself has clean effect, dissolve the carbon in the oil inside the engine, so even the replacement of oil, working for a period of time in the engine will also change, especially the mileage already long vehicles, oil blackened faster, but is not meant to be replaced immediately. So judging the replacement of Baotou northern Benz parts oil time, or to replace the mileage and time of oil is the standard.

Error two oil thinner the better

The viscosity level is a very important index of oil viscosity is too high, will cause the vehicle to bad lubrication wear degree increased, with many brands have launched a low viscosity and high film strength and more durable oil, many owners mistakenly believe that the oil viscosity is as low as possible. This is not so. The new engine internal processing accuracy is relatively high, and the old model or longer mileage of the engine, in the choice of oil is completely different. In addition, the choice of engine oil is different depending on the temperature of the region and the environment. When the user selects the engine oil, or to refer to their own conditions and the status of the engine, accurate lubrication will keep the engine in the best state of operation.

Error three oil only add not change

In the use of oil, due to wear, oxidation, cleaning and other reasons, the oil consumption in the performance will also decline. There are individual car owners will use spare oil supplement from time to time, in order to avoid changing the oil, but this can only make up for the lack of oil, and can not restore oil lubrication performance loss. In addition, the oil work needs to be filtered through the machine filter, if the statutory retirement age without changing the filter, only to supplement the oil will also cause other faults.

Misunderstanding four change additives without permission

The oil factory is composed of base oil and different additives. High quality engine oil not only has lubricity, but also has many additives in the formula, such as antifriction agent, and it also provides many protection functions to the engine. However, if the user without changing the additive components in oil, the oil component destroyed the balance, not only to the vehicle to bring extra protection, but easy to react with chemical substances in the oil, resulting in a decline in overall performance of engine oil.

Misunderstanding five preferring to add more, not less

Some drivers find their cars burning oil, so in the replacement of Baotou northern Benz parts oil, deliberately add points, but in fact, this approach is more dangerous. The oil in the crankcase is added too much, the oil is easy to flow through the push rod sleeve into the valve chamber, and then enters the combustion chamber between the valve rod and the valve guide, and the combustion will form carbon deposition. These carbon deposition will increase the engine compression ratio and increase the probability of knock. At the same time, too much oil will increase the resistance of the crankshaft connecting rod, resulting in increased fuel consumption. In addition, it will lead to the increase of the internal pressure of the Mercedes Benz parts engine in northern Baotou, resulting in the oil leakage of the engine seal. So add the oil or to add according to the specified amount.
