Engine oil is the engine's "blood", not only to protect the engine, to make the engine life longer, but also to reduce the probability of engine failure, and save fuel costs.
If used improperly, will also cause the failure of the vehicle resulted in increased fuel consumption, short service life. This "improper" method of use, generally derived from the car friend on the five kinds of errors.
Mistake one: oil turns black and then changes
The engine oil cleans the carbon and oxide inside the engine and dissolves it, and the black matter we see in the engine oil is the product of carbon deposition and oxidation in the engine. So, no matter how transparent oil, as long as the engine to join the work for a period of time will be black, this is the oil in the play of its cleaning role, not black, you have to change.
Misunderstanding two: oil often add not change
It is correct to check the engine oil regularly, but only replacing and replacing can only make up for the deficiency of the oil quantity, but can not fully compensate for the loss of lubricating oil performance. In the use of oil, due to pollution, oxidation and other reasons, the performance will gradually decline, but there will be some consumption, so that the number of reduced.
Misunderstanding three: the role of oil additives
High quality engine oil is a finished product with a variety of engine protection functions. The formulation contains a variety of additives, including anti-wear agents, and the balance of the best formula to ensure the full performance of various properties. Proper use of additives may help the car, excessive words not only can not protect, but easy to react with the chemicals in the oil, resulting in the decline in the overall performance of the engine oil.
Error four: the thinner the oil, the better
The viscosity of high-end oil is relatively low, many owners will think that the lower the viscosity of the oil, the better. In fact, the choice of oil viscosity or reference manuals, only the appropriate to achieve the best results. Of course, also need to refer to the actual conditions of the engine, viscosity is too low or too high, will lead to poor lubrication or running resistance is too large.
Mistake five: oil should be added more but not less
The amount of oil should be controlled between the upper and lower scales of the oil dipstick. Because the oil is too much, it will break into the combustion chamber from the gap between the cylinder and piston to form coke. These deposits will increase the compression ratio of the engine, increase the chance to produce knock again, extra oil will make the engine internal pressure increase, easily lead to engine seal oil leakage.
