The engine oil is the "blood", to reduce friction, lubrication, cleaning, sealing, rust proof effect, so choose a suitable oil to keep the good condition and has great relation to prolong the service life of the engine. However, some novice for oil and its effect is not very understanding, and even the existence of misunderstanding.
<strong> Misunderstanding 1</strong>
You can not change the oil
The first mistake is the most serious, the oil is certainly need to be replaced! Had a case, BMW is a female owner, she opened a BMW for 3 years, never to change the car oil, until the car finally stopped. Because in her understanding, BMW is a good car, do not need to replace the oil.
The oil is mainly divided into: mineral oil, synthetic, semi synthetic oil, mineral oil and the replacement cycle is generally semi synthetic oil is 5000-7500 km, synthetic oils can reach 8000-15000 km, in the replacement of oil needs to replace the filter (filter). If your car is a new car, the 4S staff will remind you of how many kilometers first maintenance. If your car is the second-hand car we recommend you buy after the timely replacement of oil.
<strong> Misunderstanding 2</strong>
The oil viscosity is high / low.
Some owners believe that the lubricating oil with high viscosity can protect the engine, and some owners believe that the use of low viscosity oil can be fuel-efficient, these ideas are some misunderstanding. In order to prevent the internal friction parts of the engine, the oil must have sufficient viscosity, otherwise it is impossible to form oil film protection enough in operation temperature. However, the use of high viscosity oil, the oil will lead to slow, the internal flow resistance increases, fuel consumption increased, reducing the power output of the engine.
The use of low viscosity oil, while ensuring liquidity, but the operation temperature is difficult to form oil film protection is good, will cause the damage to the engine, and will cause the loss of power. Therefore, only the correct use of oil viscosity, so the car can reach the best state.
At present, Castrol pole supporting synthetic oils can be seen in the maintenance shop, there are 4 kinds of viscosity grade, are: 0W-40, 5W-40, 5W-30, 10W-60, the most versatile is the viscosity of 0W-40. The latest pole support not only in the United States (API) standard SN grade, but also to meet the more demanding European Automobile Manufacturers Association (ACEA) A3/B3, A3/B4 grade. The new pole support not only has excellent flow properties, and integration of technology to strengthen the titanium fluid, the oil film strength to about 20% than ordinary oil, high oil film strength.
The Department of European and German models of the engine due to the high compression ratio engine, and turbocharged engine side, under normal circumstances unless it is used in winter in the northeast, we recommend 5W-40 or 10W-40 viscosity oil, because it can take into account the engine cold start performance, also highlighted the good protection of the engine the.
Japanese cars dominated by 5W-30, the high-end car even recommended by 5W-20 oil. Castrol support there is a 10W-60 of the viscosity of the oil, the viscosity of the oil is mainly used in the super car engine, the oil resistant ability (super run the engine speed is higher at high engine speeds, not because of the high temperature causes the oil viscosity decrease). The viscosity of the oil while ordinary cars can use, but also because of the higher viscosity, will reduce the phenomenon of burning oil in some models, but will lead to increased fuel consumption.
<strong> Misunderstanding 3</strong>
Oil filling quantity is too much or too little
Filling oil, should not be too much, should be in the position of the central line of the oil foot, if the oil shortage will lead to insufficient hydraulic pressure, too much will cause the crankshaft running resistance increases, accelerate the combustion chamber carbon formation.
<strong> Misunderstanding 4</strong>
Black oil is bad
Black oil does not mean oil deterioration. This is because the clean engine is one of the very important function of oil, oil clean dispersant will not fully capture the product of combustion of fuel, or other deposits, which dispersed in the oil, then the oil color will turn black. When the oil is black, this is its role in the performance of clean oil.
<strong> Misunderstanding 5</strong>
The oil can be mixed with different
Some consumers in the car during the oil less, then went to the other models are mixed, this is the wrong way. We generally do not recommend oil mix. Different brands of engine oil, additive system used is also different. In order to avoid conflict between the additives, resulting in a decline in oil performance, without access to professional advice, please carefully mixed use.
<strong> Misunderstanding 6</strong>
The indiscriminate use of oil additives
Let's take a look at what ABB says. (Note: A=Audi, B=BMW, B=Benz. )
VAG (VW, Audi, SEATt, Skoda, Volkswagen, Audi) "the use of additional additives in the engine is not allowed, all caused by the use of additional additives in loss of quality assurance in the list".
BMW (BMW) "does not assume any liability for any other additives caused by".
MercedceBenz (Benz) "there is no reason to add additional additives, we do not agree with the use of these additives in our vehicles and engines".
Any lubricating oil product is composed of a complex, balanced formula system, their mutual cooperation, jointly undertake and complete lubrication for engine protection. Any additional additives are likely to break the formula for the balance of the system, causing unexpected damage to the engine.
Therefore, suggest that you: please carefully use additional lubrication additives.
The above is easy to be ignored and neglected by the novice, the hope can give in the car maintenance is not aware of the users some help, and is willing to play to the best of your car.
