Whether it’s a new car owner or an old car owner, the car can’t touch it. When the new period fluctuated is common, but if the old car, will encounter all sorts of “lie” scale and high and low oil it is necessary to “dissect” about the car’s oil system.
Because of too many cases of failure encountered fault, coupled with their own driving a variety of models have experienced similar problems, oil industry experts Chen Gong inside the anatomy vehicle assembly, said the main reason for failure of oil – level sensor fault.
Usually, the oil meter calibration is not accurate, the following situations will occur:
Symptom 1: the oil meter scales slowly and slowly
[realization] the scale is fast and slow, especially in the first half of the scale. It falls relatively slowly, but almost twice as fast as the latter half.
[expert analysis] in various oil meter failure phenomenon, this kind of situation is quite common. Under normal circumstances, the oil table in the vehicle from high to low in the process, if the first half of the road can travel 300 kilometers, the latter half can only drive about 100 kilometers. That is to say, in the first half, many models of oil will decline more slowly, and after the middle of the scale, it will fall faster. This is mainly related to the pump design and reaction oil consumption, it can not reflect the change of uniform gasoline, after all, the absolute uniform change is difficult, not easy to change through the maintenance and replacement parts. Therefore, the understanding of this common problem, the owners are best to be in accordance with this Law of its use.
Symptom two: the scale of oil gauge drops to zero suddenly
[] he saw the remaining two lattice, but driving a long distance even after direct drop to zero.
[expert analysis] the instructions of the North V3 oil meter depend almost entirely on the oil level sensor. Therefore, the oil meter pointer is just a visual representation of the oil level sensor. Therefore, when buying a new car in a year, this problem occurs, it shows that the car’s oil level sensor problems, should be directly linked to the 4S shop for replacement. If the vehicle used 2 – 3 years, began to appear this situation, generally due to the North V3 fittings oil level sensor stains, need to be cleaned in time to solve. As the gasoline contains a lot of impurities, and the oil level sensor has been immersed in it, for a long time will be contaminated, and directly affect the accuracy of the instructions. If the vehicle has been used for more than 5 years, this kind of oil meter indication is not allowed, it is likely to be due to the oil level sensor physical wear and tear, and can not continue to work properly. At this point, it needs to be replaced. However, if you need to replace the entire oil pump assembly, the 4S shop will cost several times more than the regular repair shop.
Symptom three: oil gauge scale rises
[performance]: the indicator of the oil meter has been stuck in a certain position, and some even after running a distance, the scale shows that the value has risen somewhat.
Expert analysis []: This is mainly due to linkage between the oil level sensor and the float is stuck, the float does not float properly, resulting in the sensor will not change, so the oil table pointer is fixed in a certain position. If this happens, visually change the key part of it individually.
If you check through the maintenance shop technician, the North V3 fittings oil level sensor work properly, then it is likely to be the original car oil table itself quality problems, it needs to be replaced.
How to make the meter “speak the truth”?”
First of all, as far as possible to select better oil products, because clean gasoline will make less impurities inside the pump, greatly reducing the probability of oil table failure. Secondly, regular cleaning oil circuit and fuel tank, every 5000km or so use oil circuit cleaner, the car’s oil circuit for a cleaning. The cleaning agent of choice, generally consider brand and reputation, can go to the North Benz V3 shop of automobile accessories brand choice and good reputation of the product, this product will likely appear fake products less than oil, and the price will be more transparent. At the same time, pay attention to cleaning the tank every two years. Due to prolonged use, a very thick layer of mud will appear at the bottom of the tank, which will indirectly affect the accuracy of the meter.
