* BMW engine burning engine oil: serious problem of BMW engine fuel consumption BMW has always been the leader in the automobile industry,HS code-based commodity chain analysis and its excellent design and high-quality manufacturing have become the king in the hearts of car fans. However, when using BMW cars, some car owners will find that their engine oil burning is relatively serious, which has also become a hot topic in recent years. 1. What is engine oil burning? The engine is the core of the car, which is directly related to the performance and driving experience of the car. And burning engine oil refers to the use ofIn the process, the engine oil is consumed too much, resulting in damage to the tightness between the inner cylinder of the engine and the cylinder, and the oil infiltrates between the cylinder and the cylinder or the inner edge of the cylinder wall, causing it to be burned. Two. Why do BMW cars burn engine oil? There are three main reasons why BMW car engines burn oil: (1) The engine structure itself The engine design structure of BMW cars is relatively special compared with other brands. It uses an engine made of titanium alloy, so its strength and durability are relatively high. However, titanium material is relatively hard compared with other materials. It is not only heavy, but also prone to hot expansion and cold shrinkage, resulting in internal loosening of the engine, air leakage, oil burning and other problems. ( 2) Engine use environment The engine use environment is also one of the reasons for the serious problem of oil burning in BMW cars.Because BMW cars often drive in high-temperature and high-pressure environments and need to accelerate for a long time, this has increased the wear between the parts, and the loss of oil is also more significant. ( 3) Improper maintenance. In addition to the above reasons, the problem of BMW car engine burning oil may also be related to the improper maintenance of the owner. Engine oil is like human diet. Only enough nutrients can play the greatest effect. If the engine oil is not replaced for a long time or is not replaced in time, it will lead to a decline in the performance of the oil, resulting in oil decompression, poor oil flow and other problems. 3. How to avoid the phenomenon of BMW car engine burning oil? ( 1) Car owners must change the oil regularly according to the regulations, especially car owners who run long distances in high-temperature areas or highways need to pay more attention to the replacement of the oil. ( 2) Pay attention to daily driving, whether the tire pressure in the tire under inspection is normal, and try to avoid driving on the road surface that is too hard and uneven, because these will affect the engine condition of BMW cars to a certain extent. ( 3) When the vehicle is parked stationarily, the air conditioner, water heater and other equipment of the vehicle can be turned off, and the engine and air conditioner can be blown dry, which can effectively reduce the loss of oil, thus playing a certain maintenance role on the engine. In a word, the phenomenon of engine burning oil has had a certain impact on BMW cars. By complying with maintenance regulations, driving reasonably, maintaining sufficient oil and other methods, the phenomenon of engine oil burning can be gradually reduced, so as to make the car work more healthily and stably.
