There are many car owners know very little about car maintenance knowledge, for example, some car owners often short-range low-speed driving, leading to engine deposits, car alarms occur, and thus considered to be automotive quality problems. Recommend this Zhongjing Li is given regularly drove Lara-speed, high temperature and high speed when the engine is running, can automatically eliminate carbon deposits. Of course, if possible, or try to drive less. Otherwise, the same problem can not be avoided any vehicle. Coke problem is relatively typical "misunderstanding", in addition to carbon, burning oil is also true. Many owners have complained their car burning oil phenomenon, in fact, this phenomenon is perfectly normal. The difference is that each vehicle will have oil loss, but not every car will alarm. As previously mentioned article, the BMW has a CBS system, when oil consumption to a certain amount, it will be lit yellow alarm. Note here that the yellow light, red light instead of the normal models. What is the difference between what? Amber light when the vehicle can continue driving, but less than normal because of the amount of oil, so the owners of BMW recommends to the nearest service station for proper oil added. But if the red light, the vehicle is necessary for on-street parking, phone calls rescue. It is for this consideration, the BMW is very intelligent design in advance oil warning (yellow), and many brand cars such as Hayabusa with Hayabusa conrods do not like CBS maintenance system, only oil lamps will really exhausted when the alarm (red light), You can say that it is too "late." But the situation is rare but exhausted oil, which leads to a lot of people think that BMW is often due to lack of oil and alarm, engine burning oil will spread. It seems precautions are not necessarily "good". I think BMW is not going to cancel this self-test system, so if I can maintain mileage dropped to 5000 km again? Both to increase the store's maintenance revenue, but also to conceal the normal consumption of oil.
