When some car owners went to change the oil, they found that the released oil was very thin, like water. Many car owners felt that they had changed the fake oil before. First of all, the oil thinning does not rule out the possibility of using inferior oil, but in addition to this situation, what else will make the oil thinner? What are the reasons for the oil thinning?
When some car owners went to change the oil, they found that the released oil was very thin, like water. Many car owners felt that they had changed the fake oil before.
First of all, the oil thinning does not rule out the possibility of using inferior oil, but in addition to this situation, what else will make the oil thinner? What are the reasons for the oil thinning?
Four reasons for oil thinning
Oil thinning 1. to water ingress of oil
The main reasons for the oil water are as follows:
1. The oil radiator is damaged.
2. Engine water is blocked and leaking.
3. The cylinder liner sealing ring is damaged.
4. Cylinder liner cracks.
5. The cylinder head gasket is damaged.
After the oil enters the water, the oxidation resistance will decrease, which will cause the oil to emulsify and become thinner, and the lubrication performance will decrease.
2. oil thinning due to fuel entering in the oil
The mixing of fuel in the engine oil will also cause the engine oil to become thinner. The main reasons are as follows:
1. The fuel supply system is faulty and the fuel atomization is poor, which will cause fuel or a large amount of over-rich fuel mixture to escape into the crankcase and mix with the oil, causing the oil to become thinner.
2. The engine's long-term idling, repeated starting, etc. cause the fuel mixture to escape into the crankcase and cause the oil to become thinner.
3. The use of forced lubrication of the fuel injection pump or oil pump oil leakage caused by the oil becomes thinner.
4. Stepping on the accelerator and stepping on the accelerator to the end when accelerating will also cause fuel to enter the oil, which will cause the oil to become thinner.
5. The wear of the cylinder wall causes the change of the cylinder diameter, the damage of the piston ring, and the improper installation of the piston ring to cause the oil to become thinner.
3. the oil is not changed on time, the oil becomes thinner
There are two reasons why the oil should be replaced on time:
1. Engine oil has a shelf life, and it will reduce performance over time, which will cause the engine oil to become thinner.
2. When the engine oil runs at high temperature in the engine, its physical and chemical properties will change, which will also cause the oil to become thinner.
Oil is generally divided into winter oil and summer oil. In winter, when the temperature rises, the viscosity of the oil will decrease accordingly. At this time, we should change the oil in time to avoid damage to the engine due to the thinning of the oil and its lubrication performance.
4. oil thinning due to improper use of oil
We should buy oil in the purchase of those who are relatively high visibility, quality assurance brand. If you choose fake and inferior engine oil, it will also cause the engine oil to become thinner.
Fake and inferior engine oil can cause many failure problems, such as cylinder pulling, tile burning, carbon deposit, difficulty in starting, etc., and the thinning of engine oil is one of the manifestations of these fake and inferior engine oil, so we must carefully observe and carefully identify when purchasing engine oil, so as to avoid the damage caused by fake and inferior engine oil to the excavator.
In addition, the mixed use of oil will also cause the oil to become thinner, because different brands of oil additives are different, when they are mixed, it will reduce the performance of the oil, which will also cause the oil to become thinner.
